-Firstly in terms of structure, there is no particular concept of “Core developers” in the sense of privileged people.

As such there are repository “maintainers” who are responsible for merging pull requests as well as a “lead maintainer” who is responsible for the release cycle, overall merging, moderation and appointment of maintainers.

 Pull Request Philosophy
 -----------------------
 
-Patchsets should always be focused. For example, a pull request could add a feature, fix a bug, or refactor code; but not a mixture. Please also avoid super pull requests which attempt to do too much, are overly large, or overly complex as this makes review difficult.

-When adding a new feature, thought must be given to the long term technical debt and maintenance that feature may require after inclusion. Before proposing a new feature that will require maintenance, please consider if you are willing to maintain it (including bug fixing). If features get orphaned with no maintainer in the future, they may be removed by the Repository Maintainer.

-Patches that change Bitcoin consensus rules are considerably more involved than normal because they affect the entire ecosystem and so must be preceded by extensive mailing list discussions and have a numbered BIP. While each case will be different, one should be prepared to expend more time and effort than for other kinds of patches because of increased peer review and consensus building requirements.

-###Peer Review
+### Peer Review
 
-Anyone may participate in peer review which is expressed by comments in the pull request. Typically reviewers will review the code for obvious errors, as well as test out the patch set and opine on the technical merits of the patch. Project maintainers take into account the peer review when determining if there is consensus to merge a pull request (remember that discussions may have been spread out over github, mailing list and IRC discussions). The following language is used within pull-request comments:

+maintainers take into account the peer review when determining if there is
+consensus to merge a pull request (remember that discussions may have been
+spread out over GitHub, mailing list and IRC discussions). The following
+language is used within pull-request comments:
 
   - ACK means "I have tested the code and I agree it should be merged";
-  - NACK means "I disagree this should be merged", and must be accompanied by sound technical justification. NACKs without accompanying reasoning may be disregarded;
-  - utACK means "I have not tested the code, but I have reviewed it and it looks OK, I agree it can be merged";
+  - NACK means "I disagree this should be merged", and must be accompanied by
+    sound technical justification (or in certain cases of copyright/patent/licensing
+    issues, legal justification). NACKs without accompanying reasoning may be
+    disregarded;
+  - utACK means "I have not tested the code, but I have reviewed it and it looks
+    OK, I agree it can be merged";
   - Concept ACK means "I agree in the general principle of this pull request";
   - Nit refers to trivial, often non-blocking issues.
 
 Reviewers should include the commit hash which they reviewed in their comments.
 
-Project maintainers reserve the right to weigh the opinions of peer reviewers using common sense judgement and also may weight based on meritocracy: Those that have demonstrated a deeper commitment and understanding towards the project (over time) or have clear domain expertise may naturally have more weight, as one would expect in all walks of life.

-Where a patch set affects consensus critical code, the bar will be set much higher in terms of discussion and peer review requirements, keeping in mind that mistakes could be very costly to the wider community. This includes refactoring of consensus critical code.
-
-Where a patch set proposes to change the Bitcoin consensus, it must have been discussed extensively on the mailing list and IRC, be accompanied by a widely discussed BIP and have a generally widely perceived technical consensus of being a worthwhile change based on the judgement of the maintainers.

+discussed extensively on the mailing list and IRC, be accompanied by a widely
+discussed BIP and have a generally widely perceived technical consensus of being
+a worthwhile change based on the judgement of the maintainers.
+
+### Finding Reviewers
+
+As most reviewers are themselves developers with their own projects, the review
+process can be quite lengthy, and some amount of patience is required. If you find
+that you've been waiting for a pull request to be given attention for several
+months, there may be a number of reasons for this, some of which you can do something
+about:
+
+  - It may be because of a feature freeze due to an upcoming release. During this time,
+    only bug fixes are taken into consideration. If your pull request is a new feature,
+    it will not be prioritized until the release is over. Wait for release.
+  - It may be because the changes you are suggesting do not appeal to people. Rather than
+    nits and critique, which require effort and means they care enough to spend time on your
+    contribution, thundering silence is a good sign of widespread (mild) dislike of a given change
+    (because people don't assume *others* won't actually like the proposal). Don't take
+    that personally, though! Instead, take another critical look at what you are suggesting
+    and see if it: changes too much, is too broad, doesn't adhere to the
+    [developer notes](doc/developer-notes.md), is dangerous or insecure, is messily written, etc.
+    Identify and address any of the issues you find. Then ask e.g. on IRC if someone could give
+    their opinion on the concept itself.
+  - It may be because your code is too complex for all but a few people. And those people
+    may not have realized your pull request even exists. A great way to find people who
+    are qualified and care about the code you are touching is the
+    [Git Blame feature](https://help.github.com/articles/tracing-changes-in-a-file/). Simply
+    find the person touching the code you are touching before you and see if you can find
+    them and give them a nudge. Don't be incessant about the nudging though.
+  - Finally, if all else fails, ask on IRC or elsewhere for someone to give your pull request
+    a look. If you think you've been waiting an unreasonably long amount of time (month+) for
+    no particular reason (few lines changed, etc), this is totally fine. Try to return the favor
+    when someone else is asking for feedback on their code, and universe balances out.

-All command-line options (except for '\-conf') may be specified in a configuration file, and all configuration file options may also be specified on the command line. Command-line options override values set in the configuration file.
-.TP
-The configuration file is a list of 'setting=value' pairs, one per line, with optional comments starting with the '#' character. Please refer to bitcoind(1) for a up to date list of valid options.
-.TP
-The configuration file is not automatically created; you can create it using your favorite plain-text editor. By default, bitcoind(1) will look for a file named bitcoin.conf(5) in the bitcoin data directory, but both the data directory and the configuration file path may be changed using the '\-datadir' and '\-conf' command-line arguments.

+====================
 
-Every year newly updated files need to have its copyright headers updated to reflect the current year.
-If you run this script from the root folder it will automatically update the year on the copyright header for all
-source files if these have a git commit from the current year.
+Provides utilities for managing copyright headers of `The Bitcoin Core
+developers` in repository source files. It has three subcommands:
 
-For example a file changed in 2015 (with 2015 being the current year):
+```
+$ ./copyright_header.py report <base_directory> [verbose]
+$ ./copyright_header.py update <base_directory>
+$ ./copyright_header.py insert <file>
+```
+Running these subcommands without arguments displays a usage string.
 
-```// Copyright (c) 2009-2013 The Bitcoin Core developers```
+copyright\_header.py report \<base\_directory\> [verbose]
+---------------------------------------------------------
 
-would be changed to:
+Produces a report of all copyright header notices found inside the source files
+of a repository. Useful to quickly visualize the state of the headers.
+Specifying `verbose` will list the full filenames of files of each category.
+
+copyright\_header.py update \<base\_directory\> [verbose]
+---------------------------------------------------------
+Updates all the copyright headers of `The Bitcoin Core developers` which were
+changed in a year more recent than is listed. For example:
+```
+// Copyright (c) <firstYear>-<lastYear> The Bitcoin Core developers
+```
+will be updated to:
+```
+// Copyright (c) <firstYear>-<lastModifiedYear> The Bitcoin Core developers
+```
+where `<lastModifiedYear>` is obtained from the `git log` history.
+
+This subcommand also handles copyright headers that have only a single year. In
+those cases:
+```
+// Copyright (c) <year> The Bitcoin Core developers
+```
+will be updated to:
+```
+// Copyright (c) <year>-<lastModifiedYear> The Bitcoin Core developers
+```
+where the update is appropriate.
+
+copyright\_header.py insert \<file\>
+------------------------------------
+Inserts a copyright header for `The Bitcoin Core developers` at the top of the
+file in either Python or C++ style as determined by the file extension. If the
+file is a Python file and it has  `#!` starting the first line, the header is
+inserted in the line below it.
+
+The copyright dates will be set to be `<year_introduced>-<current_year>` where
+`<year_introduced>` is according to the `git log` history. If
+`<year_introduced>` is equal to `<current_year>`, it will be set as a single
+year rather than two hyphenated years.
+
+If the file already has a copyright for `The Bitcoin Core developers`, the
+script will exit.

+Usage: $scriptName [-c|u|v|b|s|B|o|h|j|m|] signer version
+
+Run this script from the directory containing the bitcoin, gitian-builder, gitian.sigs, and bitcoin-detached-sigs.
+
+Arguments:
+signer          GPG signer to sign each build assert file
+version		Version number, commit, or branch to build. If building a commit or branch, the -c option must be specified
+
+Options:
+-c|--commit	Indicate that the version argument is for a commit or branch
+-u|--url	Specify the URL of the repository. Default is https://github.com/bitcoin/bitcoin
+-v|--verify 	Verify the gitian build
+-b|--build	Do a gitian build
+-s|--sign	Make signed binaries for Windows and Mac OSX
+-B|--buildsign	Build both signed and unsigned binaries
+-o|--os		Specify which Operating Systems the build is for. Default is lwx. l for linux, w for windows, x for osx
+-j		Number of processes to use. Default 2
+-m		Memory to allocate in MiB. Default 2000
+--kvm           Use KVM instead of LXC
+--setup         Setup the gitian building environment. Uses KVM. If you want to use lxc, use the --lxc option. Only works on Debian-based systems (Ubuntu, Debian)
+--detach-sign   Create the assert file for detached signing. Will not commit anything.
+--no-commit     Do not commit anything to git
+-h|--help	Print this help message

+* RPC: `port`  (Default: `8332`)
+* Blockchain: `min_height`, `max_height`
+* `rev_hash_bytes`: If true, the written block hash list will be
+byte-reversed. (In other words, the hash returned by getblockhash will have its
+bytes reversed.) False by default. Intended for generation of
+standalone hash lists but safe to use with linearize-data.py, which will output
+the same data no matter which byte format is chosen.
+
+The `linearize-hashes` script requires a connection, local or remote, to a
+JSON-RPC server. Running `bitcoind` or `bitcoin-qt -server` will be sufficient.
 
 ## Step 2: Copy local block data
 
     $ ./linearize-data.py linearize.cfg
 
 Required configuration file settings:
-* "input": bitcoind blocks/ directory containing blkNNNNN.dat
-* "hashlist": text file containing list of block hashes, linearized-hashes.py
-output.
-* "output_file": bootstrap.dat
+* `output_file`: The file that will contain the final blockchain.
       or
-* "output": output directory for linearized blocks/blkNNNNN.dat output
+* `output`: Output directory for linearized `blocks/blkNNNNN.dat` output.
 
 Optional config file setting for linearize-data:
-* "netmagic": network magic number
-* "max_out_sz": maximum output file size (default `1000*1000*1000`)
-* "split_timestamp": Split files when a new month is first seen, in addition to
-reaching a maximum file size.
-* "file_timestamp": Set each file's last-modified time to that of the
-most recent block in that file.
+* `debug_output`: Some printouts may not always be desired. If true, such output
+will be printed.
+* `file_timestamp`: Set each file's last-accessed and last-modified times,
+respectively, to the current time and to the timestamp of the most recent block
+written to the script's blockchain.
+* `genesis`: The hash of the genesis block in the blockchain.
+* `input`: bitcoind blocks/ directory containing blkNNNNN.dat
+* `hashlist`: text file containing list of block hashes created by
+linearize-hashes.py.
+* `max_out_sz`: Maximum size for files created by the `output_file` option.
+(Default: `1000*1000*1000 bytes`)
+* `netmagic`: Network magic number.
+* `out_of_order_cache_sz`: If out-of-order blocks are being read, the block can
+be written to a cache so that the blockchain doesn't have to be seeked again.
+This option specifies the cache size. (Default: `100*1000*1000 bytes`)
+* `rev_hash_bytes`: If true, the block hash list written by linearize-hashes.py
+will be byte-reversed when read by linearize-data.py. See the linearize-hashes
+entry for more information.
+* `split_timestamp`: Split blockchain files when a new month is first seen, in
+addition to reaching a maximum file size (`max_out_sz`).

-### SpendFrom ###
-
-Use the raw transactions API to send coins received on a particular
-address (or addresses). 
-
-### Usage: ###
-Depends on [jsonrpc](http://json-rpc.org/).
-
-	spendfrom.py --from=FROMADDRESS1[,FROMADDRESS2] --to=TOADDRESS --amount=amount \
-	             --fee=fee --datadir=/path/to/.bitcoin --testnet --dry_run
-
-With no arguments, outputs a list of amounts associated with addresses.
-
-With arguments, sends coins received by the `FROMADDRESS` addresses to the `TOADDRESS`.
-
-### Notes ###
-
-- You may explicitly specify how much fee to pay (a fee more than 1% of the amount
-will fail,  though, to prevent bitcoin-losing accidents). Spendfrom may fail if
-it thinks the transaction would never be confirmed (if the amount being sent is
-too small, or if the transaction is too many bytes for the fee).
-
-- If a change output needs to be created, the change will be sent to the last
-`FROMADDRESS` (if you specify just one `FROMADDRESS`, change will go back to it).
-
-- If `--datadir` is not specified, the default datadir is used.
-
-- The `--dry_run` option will just create and sign the transaction and print
-the transaction data (as hexadecimal), instead of broadcasting it.
-
-- If the transaction is created and broadcast successfully, a transaction id
-is printed.
-
-- If this was a tool for end-users and not programmers, it would have much friendlier
-error-handling.

 ### Verify Binaries
+
+#### Preparation:
+
+Make sure you obtain the proper release signing key and verify the fingerprint with several independent sources.
+
+```sh
+$ gpg --fingerprint "Bitcoin Core binary release signing key"
+pub   4096R/36C2E964 2015-06-24 [expires: 2017-02-13]
+      Key fingerprint = 01EA 5486 DE18 A882 D4C2  6845 90C8 019E 36C2 E964
+uid                  Wladimir J. van der Laan (Bitcoin Core binary release signing key) <laanwj@gmail.com>
+```
+
+#### Usage:
+
 This script attempts to download the signature file `SHA256SUMS.asc` from https://bitcoin.org.
 
 It first checks if the signature passes, and then downloads the files specified in the file, and checks if the hashes of these files match those that are specified in the signature file.
 
 The script returns 0 if everything passes the checks. It returns 1 if either the signature check or the hash check doesn't pass. If an error occurs the return value is 2.
 
-Usage:
 
 ```sh
 ./verify.sh bitcoin-core-0.11.2
 ./verify.sh bitcoin-core-0.12.0
+./verify.sh bitcoin-core-0.13.0-rc3
+```
+
+If you do not want to keep the downloaded binaries, specify anything as the second parameter.
+
+```sh
+./verify.sh bitcoin-core-0.13.0 delete
 ```

 WINDOWS BUILD NOTES
 ====================
 
-Some notes on how to build Bitcoin Core for Windows.
+Below are some notes on how to build Bitcoin Core for Windows.
 
 Most developers use cross-compilation from Ubuntu to build executables for
 Windows. This is also used to build the release binaries.
 
-Building on Windows itself is possible (for example using msys / mingw-w64),
-but no one documented the steps to do this. If you are doing this, please contribute them.
+While there are potentially a number of ways to build on Windows (for example using msys / mingw-w64),
+using the Windows Subsystem For Linux is the most straightforward. If you are building with
+another method, please contribute the instructions here for others who are running versions
+of Windows that are not compatible with the Windows Subsystem for Linux.
+
+Compiling with Windows Subsystem For Linux
+-------------------------------------------
+
+With Windows 10, Microsoft has released a new feature named the [Windows
+Subsystem for Linux](https://msdn.microsoft.com/commandline/wsl/about). This
+feature allows you to run a bash shell directly on Windows in an Ubuntu-based
+environment. Within this environment you can cross compile for Windows without
+the need for a separate Linux VM or server.
+
+This feature is not supported in versions of Windows prior to Windows 10 or on
+Windows Server SKUs. In addition, it is available [only for 64-bit versions of
+Windows](https://msdn.microsoft.com/en-us/commandline/wsl/install_guide).
+
+To get the bash shell, you must first activate the feature in Windows.
+
+1. Turn on Developer Mode
+  * Open Settings -> Update and Security -> For developers
+  * Select the Developer Mode radio button
+  * Restart if necessary
+2. Enable the Windows Subsystem for Linux feature
+  * From Start, search for "Turn Windows features on or off" (type 'turn')
+  * Select Windows Subsystem for Linux (beta)

+----------
+
+Several parts of the repository are subtrees of software maintained elsewhere.
+
+Some of these are maintained by active developers of Bitcoin Core, in which case changes should probably go
+directly upstream without being PRed directly against the project.  They will be merged back in the next
+subtree merge.
+
+Others are external projects without a tight relationship with our project.  Changes to these should also
+be sent upstream but bugfixes may also be prudent to PR against Bitcoin Core so that they can be integrated
+quickly.  Cosmetic changes should be purely taken upstream.
+
+There is a tool in contrib/devtools/git-subtree-check.sh to check a subtree directory for consistency with
+its upstream repository.
+
+Current subtrees include:

+
+RPC interface guidelines
+--------------------------
+
+A few guidelines for introducing and reviewing new RPC interfaces:
+
+- Method naming: use consecutive lower-case names such as `getrawtransaction` and `submitblock`
+
+  - *Rationale*: Consistency with existing interface.
+
+- Argument naming: use snake case `fee_delta` (and not, e.g. camel case `feeDelta`)
+
+  - *Rationale*: Consistency with existing interface.
+
+- Use the JSON parser for parsing, don't manually parse integers or strings from
+  arguments unless absolutely necessary.
+
+  - *Rationale*: Introduces hand-rolled string manipulation code at both the caller and callee sites,
+    which is error prone, and it is easy to get things such as escaping wrong.
+    JSON already supports nested data structures, no need to re-invent the wheel.
+
+  - *Exception*: AmountToValue can parse amounts as string. This was introduced because many JSON
+    parsers and formatters hard-code handling decimal numbers as floating point
+    values, resulting in potential loss of precision. This is unacceptable for
+    monetary values. **Always** use `AmountToValue` and `ValueToAmount` when
+    inputting or outputting monetary values. The only exceptions to this are
+    `prioritisetransaction` and `getblocktemplate` because their interface
+    is specified as-is in BIP22.
+
+- Missing arguments and 'null' should be treated the same: as default values. If there is no
+  default value, both cases should fail in the same way.
+
+  - *Rationale*: Avoids surprises when switching to name-based arguments. Missing name-based arguments
+  are passed as 'null'.
+
+  - *Exception*: Many legacy exceptions to this exist, one of the worst ones is
+    `getbalance` which follows a completely different code path based on the
+    number of arguments. We are still in the process of cleaning these up. Do not introduce
+    new ones.
+
+- Try not to overload methods on argument type. E.g. don't make `getblock(true)` and `getblock("hash")`
+  do different things.
+
+  - *Rationale*: This is impossible to use with `bitcoin-cli`, and can be surprising to users.
+
+  - *Exception*: Some RPC calls can take both an `int` and `bool`, most notably when a bool was switched
+    to a multi-value, or due to other historical reasons. **Always** have false map to 0 and
+    true to 1 in this case.
+
+- Don't forget to fill in the argument names correctly in the RPC command table.
+
+  - *Rationale*: If not, the call can not be used with name-based arguments.
+
+- Set okSafeMode in the RPC command table to a sensible value: safe mode is when the
+  blockchain is regarded to be in a confused state, and the client deems it unsafe to
+  do anything irreversible such as send. Anything that just queries should be permitted.
+
+  - *Rationale*: Troubleshooting a node in safe mode is difficult if half the
+    RPCs don't work.
+
+- Add every non-string RPC argument `(method, idx, name)` to the table `vRPCConvertParams` in `rpc/client.cpp`.
+
+  - *Rationale*: `bitcoin-cli` and the GUI debug console use this table to determine how to
+    convert a plaintext command line to JSON. If the types don't match, the method can be unusable
+    from there.
+
+- A RPC method must either be a wallet method or a non-wallet method. Do not
+  introduce new methods such as `getinfo` and `signrawtransaction` that differ
+  in behavior based on presence of a wallet.
+
+  - *Rationale*: as well as complicating the implementation and interfering
+    with the introduction of multi-wallet, wallet and non-wallet code should be
+    separated to avoid introducing circular dependencies between code units.

+Fuzz-testing Bitcoin Core
+==========================
+
+A special test harness `test_bitcoin_fuzzy` is provided to provide an easy
+entry point for fuzzers and the like. In this document we'll describe how to
+use it with AFL.
+
+Building AFL
+-------------
+
+It is recommended to always use the latest version of afl:
+```
+wget http://lcamtuf.coredump.cx/afl/releases/afl-latest.tgz
+tar -zxvf afl-latest.tgz
+cd afl-<version>
+make
+export AFLPATH=$PWD
+```
+
+Instrumentation
+----------------
+
+To build Bitcoin Core using AFL instrumentation (this assumes that the
+`AFLPATH` was set as above):
+```
+./configure --disable-ccache --disable-shared --enable-tests CC=${AFLPATH}/afl-gcc CXX=${AFLPATH}/afl-g++
+export AFL_HARDEN=1
+cd src/
+make test/test_bitcoin_fuzzy
+```
+We disable ccache because we don't want to pollute the ccache with instrumented
+objects, and similarly don't want to use non-instrumented cached objects linked
+in.
+
+Preparing fuzzing
+------------------
+
+AFL needs an input directory with examples, and an output directory where it
+will place examples that it found. These can be anywhere in the file system,
+we'll define environment variables to make it easy to reference them.
+
+```
+mkdir inputs
+AFLIN=$PWD/inputs
+mkdir outputs
+AFLOUT=$PWD/outputs
+```
+
+Example inputs are available from:
+
+- https://download.visucore.com/bitcoin/bitcoin_fuzzy_in.tar.xz
+- http://strateman.ninja/fuzzing.tar.xz
+
+Extract these (or other starting inputs) into the `inputs` directory before starting fuzzing.
+
+Fuzzing
+--------
+
+To start the actual fuzzing use:
+```
+$AFLPATH/afl-fuzz -i ${AFLIN} -o ${AFLOUT} -m52 -- test/test_bitcoin_fuzzy
+```
+
+You may have to change a few kernel parameters to test optimally - `afl-fuzz`
+will print an error and suggestion if so.

-Multiwallet Qt Development and Integration Strategy
-===================================================
-
-In order to support loading of multiple wallets in bitcoin-qt, a few changes in the UI architecture will be needed.
-Fortunately, only four of the files in the existing project are affected by this change.
-
-Two new classes have been implemented in two new .h/.cpp file pairs, with much of the functionality that was previously
-implemented in the BitcoinGUI class moved over to these new classes.
-
-The two existing files most affected, by far, are bitcoingui.h and bitcoingui.cpp, as the BitcoinGUI class will require
-some major retrofitting.
-
-Only requiring some minor changes is bitcoin.cpp.
-
-Finally, two new headers and source files will have to be added to bitcoin-qt.pro.
-
-Changes to class BitcoinGUI
----------------------------
-The principal change to the BitcoinGUI class concerns the QStackedWidget instance called centralWidget.
-This widget owns five page views: overviewPage, transactionsPage, addressBookPage, receiveCoinsPage, and sendCoinsPage.
-
-A new class called *WalletView* inheriting from QStackedWidget has been written to handle all renderings and updates of
-these page views. In addition to owning these five page views, a WalletView also has a pointer to a WalletModel instance.
-This allows the construction of multiple WalletView objects, each rendering a distinct wallet.
-
-A second class called *WalletFrame* inheriting from QFrame has been written as a container for embedding all wallet-related
-controls into BitcoinGUI. At present it contains the WalletView instances for the wallets and does little more than passing on messages
-from BitcoinGUI to the currently selected WalletView. It is a WalletFrame instance
-that takes the place of what used to be centralWidget in BitcoinGUI. The purpose of this class is to allow future
-refinements of the wallet controls with minimal need for further modifications to BitcoinGUI, thus greatly simplifying
-merges while reducing the risk of breaking top-level stuff.
-
-Changes to bitcoin.cpp
-----------------------
-bitcoin.cpp is the entry point into bitcoin-qt, and as such, will require some minor modifications to provide hooks for
-multiple wallet support. Most importantly will be the way it instantiates WalletModels and passes them to the
-singleton BitcoinGUI instance called window. Formerly, BitcoinGUI kept a pointer to a single instance of a WalletModel.
-The initial change required is very simple: rather than calling `window.setWalletModel(&walletModel);` we perform the
-following two steps:
-
-	window.addWallet("~Default", &walletModel);
-	window.setCurrentWallet("~Default");
-
-The string parameter is just an arbitrary name given to the default wallet. It's been prepended with a tilde to avoid name collisions in the future with additional wallets.
-
-The shutdown call `window.setWalletModel(0)` has also been removed. In its place is now:
-
-window.removeAllWallets();

-updates will be released anymore. Without security updates, using a bitcoin
-wallet on a XP machine is irresponsible at least.
+Bitcoin Core is extensively tested on multiple operating systems using

-In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
-randomly crashing on Windows XP. It is [not clear](https://github.com/bitcoin/bitcoin/issues/7681#issuecomment-217439891)
-what the source of these crashes is, but it is likely that upstream

 Notable changes
 ===============
 
-Database cache memory increased
---------------------------------
-
-As a result of growth of the UTXO set, performance with the prior default
-database cache of 100 MiB has suffered.
-For this reason the default was changed to 300 MiB in this release.
-
-For nodes on low-memory systems, the database cache can be changed back to
-100 MiB (or to another value) by either:
-
-- Adding `dbcache=100` in bitcoin.conf
-- Changing it in the GUI under `Options → Size of database cache`
-
-Note that the database cache setting has the most performance impact
-during initial sync of a node, and when catching up after downtime.
-
-bitcoin-cli: arguments privacy
---------------------------------
-
-The RPC command line client gained a new argument, `-stdin`
-to read extra arguments from standard input, one per line until EOF/Ctrl-D.
-For example:
-
-    $ echo -e "mysecretcode\n120" | src/bitcoin-cli -stdin walletpassphrase
-
-It is recommended to use this for sensitive information such as wallet
-passphrases, as command-line arguments can usually be read from the process
-table by any user on the system.
-
-RPC low-level changes
-----------------------
-
-- `gettxoutsetinfo` UTXO hash (`hash_serialized`) has changed. There was a divergence between
-  32-bit and 64-bit platforms, and the txids were missing in the hashed data. This has been
-  fixed, but this means that the output will be different than from previous versions.
-
-- Full UTF-8 support in the RPC API. Non-ASCII characters in, for example,
-  wallet labels have always been malformed because they weren't taken into account
-  properly in JSON RPC processing. This is no longer the case. This also affects
-  the GUI debug console.
-
-C++11 and Python 3
--------------------
-
-Various code modernizations have been done. The Bitcoin Core code base has
-started using C++11. This means that a C++11-capable compiler is now needed for
-building. Effectively this means GCC 4.7 or higher, or Clang 3.3 or higher.
-
-When cross-compiling for a target that doesn't have C++11 libraries, configure with
-`./configure --enable-glibc-back-compat ... LDFLAGS=-static-libstdc++`.
-
-For running the functional tests in `qa/rpc-tests`, Python3.4 or higher is now
-required.
-
-Linux ARM builds
-------------------
-
-Due to popular request, Linux ARM builds have been added to the uploaded
-executables.
-
-The following extra files can be found in the download directory or torrent:
-
-- `bitcoin-${VERSION}-arm-linux-gnueabihf.tar.gz`: Linux binaries for the most
-  common 32-bit ARM architecture.
-- `bitcoin-${VERSION}-aarch64-linux-gnu.tar.gz`: Linux binaries for the most
-  common 64-bit ARM architecture.
-
-ARM builds are still experimental. If you have problems on a certain device or
-Linux distribution combination please report them on the bug tracker, it may be
-possible to resolve them.
-
-Note that Android is not considered ARM Linux in this context. The executables
-are not expected to work out of the box on Android.
-
-0.13.0 Change log
-=================
-
-Detailed release notes follow. This overview includes changes that affect
-behavior, not code moves, refactors and string updates. For convenience in locating
-the code changes and accompanying discussion, both the pull request and
-git merge commit are mentioned.
-
-### RPC and REST
-
-Asm script outputs replacements for OP_NOP2 and OP_NOP3
--------------------------------------------------------
-
-OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by [BIP 
-65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki)
-
-OP_NOP3 has been renamed to OP_CHECKSEQUENCEVERIFY by [BIP 
-112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki)
-
-The following outputs are affected by this change:
-- RPC `getrawtransaction` (in verbose mode)
-- RPC `decoderawtransaction`
-- RPC `decodescript`
-- REST `/rest/tx/` (JSON format)
-- REST `/rest/block/` (JSON format when including extended tx details)
-- `bitcoin-tx -json`
-
-New mempool information RPC calls
----------------------------------
-
-RPC calls have been added to output detailed statistics for individual mempool
-entries, as well as to calculate the in-mempool ancestors or descendants of a
-transaction: see `getmempoolentry`, `getmempoolancestors`, `getmempooldescendants`.
-
-### ZMQ
-
-Each ZMQ notification now contains an up-counting sequence number that allows
-listeners to detect lost notifications.
-The sequence number is always the last element in a multi-part ZMQ notification and
-therefore backward compatible.
-Each message type has its own counter.
-(https://github.com/bitcoin/bitcoin/pull/7762)
-
-### Configuration and command-line options
-
-### Block and transaction handling
-
-### P2P protocol and network code
-
-The p2p alert system has been removed in #7692 and the 'alert' message is no longer supported.
-
-
-Fee filtering of invs (BIP 133)
-------------------------------------
-
-The optional new p2p message "feefilter" is implemented and the protocol
-version is bumped to 70013. Upon receiving a feefilter message from a peer,
-a node will not send invs for any transactions which do not meet the filter
-feerate. [BIP 133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki)
-
-### Validation
-
-### Build system
-
-### Wallet
-
-Hierarchical Deterministic Key Generation
------------------------------------------
-Newly created wallets will use hierarchical deterministic key generation
-according to BIP32 (keypath m/0'/0'/k').
-Existing wallets will still use traditional key generation.
-
-Backups of HD wallets, regardless of when they have been created, can
-therefore be used to re-generate all possible private keys, even the
-ones which haven't already been generated during the time of the backup.
-
-HD key generation for new wallets can be disabled by `-usehd=0`. Keep in
-mind that this flag only has affect on newly created wallets.
-You can't disable HD key generation once you have created a HD wallet.
-
-There is no distinction between internal (change) and external keys.

+Upgrading and downgrading
+=========================
+
+How to Upgrade
+--------------
+
+If you are running an older version, shut it down. Wait until it has completely
+shut down (which might take a few minutes for older versions), then run the
+installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
+bitcoind/bitcoin-qt (on Linux).
+
+Downgrade warning
+-----------------
+
+### Downgrade to a version < 0.12.0
+
+Because release 0.12.0 and later will obfuscate the chainstate on every
+fresh sync or reindex, the chainstate is not backwards-compatible with
+pre-0.12 versions of Bitcoin Core or other software.
+
+If you want to downgrade after you have done a reindex with 0.12.0 or later,
+you will need to reindex when you first start Bitcoin Core version 0.11 or
+earlier.
+
+Notable changes
+===============
+
+First version bits BIP9 softfork deployment
+-------------------------------------------
+
+This release includes a soft fork deployment to enforce [BIP68][],
+[BIP112][] and [BIP113][] using the [BIP9][] deployment mechanism.
+
+The deployment sets the block version number to 0x20000001 between
+midnight 1st May 2016 and midnight 1st May 2017 to signal readiness for 
+deployment. The version number consists of 0x20000000 to indicate version
+bits together with setting bit 0 to indicate support for this combined
+deployment, shown as "csv" in the `getblockchaininfo` RPC call.
+
+For more information about the soft forking change, please see
+<https://github.com/bitcoin/bitcoin/pull/7648>
+
+This specific backport pull-request can be viewed at
+<https://github.com/bitcoin/bitcoin/pull/7543>
+
+[BIP9]: https://github.com/bitcoin/bips/blob/master/bip-0009.mediawiki
+[BIP68]: https://github.com/bitcoin/bips/blob/master/bip-0068.mediawiki
+[BIP112]: https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki
+[BIP113]: https://github.com/bitcoin/bips/blob/master/bip-0113.mediawiki
+
+BIP68 soft fork to enforce sequence locks for relative locktime
+---------------------------------------------------------------
+
+[BIP68][] introduces relative lock-time consensus-enforced semantics of
+the sequence number field to enable a signed transaction input to remain
+invalid for a defined period of time after confirmation of its corresponding
+outpoint.
+
+For more information about the implementation, see
+<https://github.com/bitcoin/bitcoin/pull/7184>
+
+BIP112 soft fork to enforce OP_CHECKSEQUENCEVERIFY
+--------------------------------------------------
+
+[BIP112][] redefines the existing OP_NOP3 as OP_CHECKSEQUENCEVERIFY (CSV)
+for a new opcode in the Bitcoin scripting system that in combination with
+[BIP68][] allows execution pathways of a script to be restricted based
+on the age of the output being spent.
+
+For more information about the implementation, see
+<https://github.com/bitcoin/bitcoin/pull/7524>
+
+BIP113 locktime enforcement soft fork
+-------------------------------------
+
+Bitcoin Core 0.11.2 previously introduced mempool-only locktime
+enforcement using GetMedianTimePast(). This release seeks to
+consensus enforce the rule.
+
+Bitcoin transactions currently may specify a locktime indicating when
+they may be added to a valid block.  Current consensus rules require
+that blocks have a block header time greater than the locktime specified
+in any transaction in that block.
+
+Miners get to choose what time they use for their header time, with the
+consensus rule being that no node will accept a block whose time is more
+than two hours in the future.  This creates a incentive for miners to
+set their header times to future values in order to include locktimed
+transactions which weren't supposed to be included for up to two more
+hours.
+
+The consensus rules also specify that valid blocks may have a header
+time greater than that of the median of the 11 previous blocks.  This
+GetMedianTimePast() time has a key feature we generally associate with
+time: it can't go backwards.
+
+[BIP113][] specifies a soft fork enforced in this release that
+weakens this perverse incentive for individual miners to use a future
+time by requiring that valid blocks have a computed GetMedianTimePast()
+greater than the locktime specified in any transaction in that block.
+
+Mempool inclusion rules currently require transactions to be valid for
+immediate inclusion in a block in order to be accepted into the mempool.
+This release begins applying the BIP113 rule to received transactions,
+so transaction whose time is greater than the GetMedianTimePast() will
+no longer be accepted into the mempool.
+
+**Implication for miners:** you will begin rejecting transactions that
+would not be valid under BIP113, which will prevent you from producing
+invalid blocks when BIP113 is enforced on the network. Any
+transactions which are valid under the current rules but not yet valid
+under the BIP113 rules will either be mined by other miners or delayed
+until they are valid under BIP113. Note, however, that time-based
+locktime transactions are more or less unseen on the network currently.
+
+**Implication for users:** GetMedianTimePast() always trails behind the
+current time, so a transaction locktime set to the present time will be
+rejected by nodes running this release until the median time moves
+forward. To compensate, subtract one hour (3,600 seconds) from your
+locktimes to allow those transactions to be included in mempools at
+approximately the expected time.
+
+For more information about the implementation, see
+<https://github.com/bitcoin/bitcoin/pull/6566>

+Bitcoin Core version 0.13.0 is now available from:
+
+  <https://bitcoin.org/bin/bitcoin-core-0.13.0/>
+
+This is a new major version release, including new features, various bugfixes
+and performance improvements, as well as updated translations.
+
+Please report bugs using the issue tracker at github:
+
+  <https://github.com/bitcoin/bitcoin/issues>

+
+Compatibility
+==============
+
+Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support),
+an OS initially released in 2001. This means that not even critical security
+updates will be released anymore. Without security updates, using a bitcoin
+wallet on a XP machine is irresponsible at least.
+
+In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
+randomly crashing on Windows XP. It is [not clear](https://github.com/bitcoin/bitcoin/issues/7681#issuecomment-217439891)
+what the source of these crashes is, but it is likely that upstream
+libraries such as Qt are no longer being tested on XP.
+
+We do not have time nor resources to provide support for an OS that is
+end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are
+suggested to upgrade to a newer verion of Windows, or install an alternative OS
+that is supported.
+
+No attempt is made to prevent installing or running the software on Windows XP,
+you can still do so at your own risk, but do not expect it to work: do not
+report issues about Windows XP to the issue tracker.
+
+Notable changes
+===============
+
+Database cache memory increased
+--------------------------------
+
+As a result of growth of the UTXO set, performance with the prior default
+database cache of 100 MiB has suffered.
+For this reason the default was changed to 300 MiB in this release.
+
+For nodes on low-memory systems, the database cache can be changed back to
+100 MiB (or to another value) by either:
+
+- Adding `dbcache=100` in bitcoin.conf
+- Changing it in the GUI under `Options → Size of database cache`
+
+Note that the database cache setting has the most performance impact
+during initial sync of a node, and when catching up after downtime.
+
+
+bitcoin-cli: arguments privacy
+------------------------------
+
+The RPC command line client gained a new argument, `-stdin`
+to read extra arguments from standard input, one per line until EOF/Ctrl-D.
+For example:
+
+    $ src/bitcoin-cli -stdin walletpassphrase
+    mysecretcode
+    120
+    ..... press Ctrl-D here to end input
+    $
+
+It is recommended to use this for sensitive information such as wallet
+passphrases, as command-line arguments can usually be read from the process
+table by any user on the system.
+
+
+C++11 and Python 3
+------------------
+
+Various code modernizations have been done. The Bitcoin Core code base has
+started using C++11. This means that a C++11-capable compiler is now needed for
+building. Effectively this means GCC 4.7 or higher, or Clang 3.3 or higher.
+
+When cross-compiling for a target that doesn't have C++11 libraries, configure with
+`./configure --enable-glibc-back-compat ... LDFLAGS=-static-libstdc++`.
+
+For running the functional tests in `qa/rpc-tests`, Python3.4 or higher is now
+required.
+
+
+Linux ARM builds
+----------------
+
+Due to popular request, Linux ARM builds have been added to the uploaded
+executables.
+
+The following extra files can be found in the download directory or torrent:
+
+- `bitcoin-${VERSION}-arm-linux-gnueabihf.tar.gz`: Linux binaries targeting
+  the 32-bit ARMv7-A architecture.
+- `bitcoin-${VERSION}-aarch64-linux-gnu.tar.gz`: Linux binaries targeting
+  the 64-bit ARMv8-A architecture.
+
+ARM builds are still experimental. If you have problems on a certain device or
+Linux distribution combination please report them on the bug tracker, it may be
+possible to resolve them. Note that the device you use must be (backward)
+compatible with the architecture targeted by the binary that you use.
+For example, a Raspberry Pi 2 Model B or Raspberry Pi 3 Model B (in its 32-bit
+execution state) device, can run the 32-bit ARMv7-A targeted binary. However,
+no model of Raspberry Pi 1 device can run either binary because they are all
+ARMv6 architecture devices that are not compatible with ARMv7-A or ARMv8-A.
+
+Note that Android is not considered ARM Linux in this context. The executables
+are not expected to work out of the box on Android.
+
+
+Compact Block support (BIP 152)
+-------------------------------
+
+Support for block relay using the Compact Blocks protocol has been implemented
+in PR 8068.
+
+The primary goal is reducing the bandwidth spikes at relay time, though in many
+cases it also reduces propagation delay. It is automatically enabled between
+compatible peers.
+[BIP 152](https://github.com/bitcoin/bips/blob/master/bip-0152.mediawiki)
+
+As a side-effect, ordinary non-mining nodes will download and upload blocks
+faster if those blocks were produced by miners using similar transaction
+filtering policies. This means that a miner who produces a block with many
+transactions discouraged by your node will be relayed slower than one with
+only transactions already in your memory pool. The overall effect of such
+relay differences on the network may result in blocks which include widely-
+discouraged transactions losing a stale block race, and therefore miners may
+wish to configure their node to take common relay policies into consideration.
+
+
+Hierarchical Deterministic Key Generation
+-----------------------------------------
+Newly created wallets will use hierarchical deterministic key generation
+according to BIP32 (keypath m/0'/0'/k').
+Existing wallets will still use traditional key generation.
+
+Backups of HD wallets, regardless of when they have been created, can
+therefore be used to re-generate all possible private keys, even the
+ones which haven't already been generated during the time of the backup.
+**Attention:** Encrypting the wallet will create a new seed which requires
+a new backup!
+
+Wallet dumps (created using the `dumpwallet` RPC) will contain the deterministic
+seed. This is expected to allow future versions to import the seed and all
+associated funds, but this is not yet implemented.
+
+HD key generation for new wallets can be disabled by `-usehd=0`. Keep in
+mind that this flag only has affect on newly created wallets.
+You can't disable HD key generation once you have created a HD wallet.
+
+There is no distinction between internal (change) and external keys.
+
+HD wallets are incompatible with older versions of Bitcoin Core.

+[Pull request](https://github.com/bitcoin/bitcoin/pull/8035/files), [BIP 32](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki)
+
+
+Segregated Witness
+------------------
+
+The code preparations for Segregated Witness ("segwit"), as described in [BIP
+141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki), [BIP
+143](https://github.com/bitcoin/bips/blob/master/bip-0143.mediawiki), [BIP
+144](https://github.com/bitcoin/bips/blob/master/bip-0144.mediawiki), and [BIP
+145](https://github.com/bitcoin/bips/blob/master/bip-0145.mediawiki) are
+finished and included in this release.  However, BIP 141 does not yet specify
+activation parameters on mainnet, and so this release does not support segwit
+use on mainnet.  Testnet use is supported, and after BIP 141 is updated with
+proposed parameters, a future release of Bitcoin Core is expected that
+implements those parameters for mainnet.
+
+Furthermore, because segwit activation is not yet specified for mainnet,
+version 0.13.0 will behave similarly as other pre-segwit releases even after a
+future activation of BIP 141 on the network.  Upgrading from 0.13.0 will be
+required in order to utilize segwit-related features on mainnet (such as signal
+BIP 141 activation, mine segwit blocks, fully validate segwit blocks, relay
+segwit blocks to other segwit nodes, and use segwit transactions in the
+wallet, etc).
+
+
+Mining transaction selection ("Child Pays For Parent")
+------------------------------------------------------
+
+The mining transaction selection algorithm has been replaced with an algorithm
+that selects transactions based on their feerate inclusive of unconfirmed
+ancestor transactions.  This means that a low-fee transaction can become more
+likely to be selected if a high-fee transaction that spends its outputs is
+relayed.
+
+With this change, the `-blockminsize` command line option has been removed.
+
+The command line option `-blockmaxsize` remains an option to specify the
+maximum number of serialized bytes in a generated block.  In addition, the new
+command line option `-blockmaxweight` has been added, which specifies the
+maximum "block weight" of a generated block, as defined by [BIP 141 (Segregated
+Witness)] (https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki).
+
+In preparation for Segregated Witness, the mining algorithm has been modified
+to optimize transaction selection for a given block weight, rather than a given
+number of serialized bytes in a block.  In this release, transaction selection
+is unaffected by this distinction (as BIP 141 activation is not supported on
+mainnet in this release, see above), but in future releases and after BIP 141
+activation, these calculations would be expected to differ.
+
+For optimal runtime performance, miners using this release should specify
+`-blockmaxweight` on the command line, and not specify `-blockmaxsize`.
+Additionally (or only) specifying `-blockmaxsize`, or relying on default
+settings for both, may result in performance degradation, as the logic to
+support `-blockmaxsize` performs additional computation to ensure that
+constraint is met.  (Note that for mainnet, in this release, the equivalent
+parameter for `-blockmaxweight` would be four times the desired
+`-blockmaxsize`.  See [BIP 141]
+(https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki) for additional
+details.)
+
+In the future, the `-blockmaxsize` option may be removed, as block creation is
+no longer optimized for this metric.  Feedback is requested on whether to
+deprecate or keep this command line option in future releases.
+
+
+Reindexing changes
+------------------
+
+In earlier versions, reindexing did validation while reading through the block
+files on disk. These two have now been split up, so that all blocks are known
+before validation starts. This was necessary to make certain optimizations that
+are available during normal synchronizations also available during reindexing.
+
+The two phases are distinct in the Bitcoin-Qt GUI. During the first one,
+"Reindexing blocks on disk" is shown. During the second (slower) one,
+"Processing blocks on disk" is shown.
+
+It is possible to only redo validation now, without rebuilding the block index,
+using the command line option `-reindex-chainstate` (in addition to
+`-reindex` which does both). This new option is useful when the blocks on disk
+are assumed to be fine, but the chainstate is still corrupted. It is also
+useful for benchmarks.
+
+
+Removal of internal miner
+--------------------------
+
+As CPU mining has been useless for a long time, the internal miner has been
+removed in this release, and replaced with a simpler implementation for the
+test framework.
+
+The overall result of this is that `setgenerate` RPC call has been removed, as
+well as the `-gen` and `-genproclimit` command-line options.
+
+For testing, the `generate` call can still be used to mine a block, and a new
+RPC call `generatetoaddress` has been added to mine to a specific address. This
+works with wallet disabled.
+
+
+New bytespersigop implementation
+--------------------------------
+
+The former implementation of the bytespersigop filter accidentally broke bare
+multisig (which is meant to be controlled by the `permitbaremultisig` option),
+since the consensus protocol always counts these older transaction forms as 20
+sigops for backwards compatibility. Simply fixing this bug by counting more
+accurately would have reintroduced a vulnerability. It has therefore been
+replaced with a new implementation that rather than filter such transactions,
+instead treats them (for fee purposes only) as if they were in fact the size
+of a transaction actually using all 20 sigops.
+
+
+Low-level P2P changes
+----------------------
+
+- The optional new p2p message "feefilter" is implemented and the protocol
+  version is bumped to 70013. Upon receiving a feefilter message from a peer,
+  a node will not send invs for any transactions which do not meet the filter
+  feerate. [BIP 133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki)
+
+- The P2P alert system has been removed in PR #7692 and the `alert` P2P message
+  is no longer supported.
+
+- The transaction relay mechanism used to relay one quarter of all transactions
+  instantly, while queueing up the rest and sending them out in batch. As
+  this resulted in chains of dependent transactions being reordered, it
+  systematically hurt transaction relay. The relay code was redesigned in PRs
+  \#7840 and #8082, and now always batches transactions announcements while also
+  sorting them according to dependency order. This significantly reduces orphan
+  transactions. To compensate for the removal of instant relay, the frequency of
+  batch sending was doubled for outgoing peers.
+
+- Since PR #7840 the BIP35 `mempool` command is also subject to batch processing.
+  Also the `mempool` message is no longer handled for non-whitelisted peers when
+  `NODE_BLOOM` is disabled through `-peerbloomfilters=0`.
+
+- The maximum size of orphan transactions that are kept in memory until their
+  ancestors arrive has been raised in PR #8179 from 5000 to 99999 bytes. They
+  are now also removed from memory when they are included in a block, conflict
+  with a block, and time out after 20 minutes.
+
+- We respond at most once to a getaddr request during the lifetime of a
+  connection since PR #7856.
+
+- Connections to peers who have recently been the first one to give us a valid
+  new block or transaction are protected from disconnections since PR #8084.
+
+
+Low-level RPC changes
+----------------------
+
+- RPC calls have been added to output detailed statistics for individual mempool
+  entries, as well as to calculate the in-mempool ancestors or descendants of a
+  transaction: see `getmempoolentry`, `getmempoolancestors`, `getmempooldescendants`.
+
+- `gettxoutsetinfo` UTXO hash (`hash_serialized`) has changed. There was a divergence between
+  32-bit and 64-bit platforms, and the txids were missing in the hashed data. This has been
+  fixed, but this means that the output will be different than from previous versions.
+
+- Full UTF-8 support in the RPC API. Non-ASCII characters in, for example,
+  wallet labels have always been malformed because they weren't taken into account
+  properly in JSON RPC processing. This is no longer the case. This also affects
+  the GUI debug console.
+
+- Asm script outputs replacements for OP_NOP2 and OP_NOP3
+
+  - OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by [BIP 
+65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki)
+
+  - OP_NOP3 has been renamed to OP_CHECKSEQUENCEVERIFY by [BIP 
+112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki)
+
+  - The following outputs are affected by this change:
+
+    - RPC `getrawtransaction` (in verbose mode)
+    - RPC `decoderawtransaction`
+    - RPC `decodescript`
+    - REST `/rest/tx/` (JSON format)
+    - REST `/rest/block/` (JSON format when including extended tx details)
+    - `bitcoin-tx -json`
+
+- The sorting of the output of the `getrawmempool` output has changed.
+
+- New RPC commands: `generatetoaddress`, `importprunedfunds`, `removeprunedfunds`, `signmessagewithprivkey`,
+  `getmempoolancestors`, `getmempooldescendants`, `getmempoolentry`,
+  `createwitnessaddress`, `addwitnessaddress`.
+
+- Removed RPC commands: `setgenerate`, `getgenerate`.
+
+- New options were added to `fundrawtransaction`: `includeWatching`, `changeAddress`, `changePosition` and `feeRate`.
+
+
+Low-level ZMQ changes
+----------------------
+
+- Each ZMQ notification now contains an up-counting sequence number that allows
+  listeners to detect lost notifications.
+  The sequence number is always the last element in a multi-part ZMQ notification and
+  therefore backward compatible. Each message type has its own counter.
+  PR [#7762](https://github.com/bitcoin/bitcoin/pull/7762).

+Bitcoin Core version 0.13.1 is now available from:
+
+  <https://bitcoin.org/bin/bitcoin-core-0.13.1/>

+updated translations.
+
+Please report bugs using the issue tracker at github:

+
+Compatibility
+==============
+
+Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support),
+an OS initially released in 2001. This means that not even critical security
+updates will be released anymore. Without security updates, using a bitcoin
+wallet on a XP machine is irresponsible at least.
+
+In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
+randomly crashing on Windows XP. It is [not clear](https://github.com/bitcoin/bitcoin/issues/7681#issuecomment-217439891)
+what the source of these crashes is, but it is likely that upstream
+libraries such as Qt are no longer being tested on XP.
+
+We do not have time nor resources to provide support for an OS that is
+end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are
+suggested to upgrade to a newer version of Windows, or install an alternative OS
+that is supported.
+
+No attempt is made to prevent installing or running the software on Windows XP,
+you can still do so at your own risk, but do not expect it to work: do not
+report issues about Windows XP to the issue tracker.
+
+From 0.13.1 onwards OS X 10.7 is no longer supported. 0.13.0 was intended to work on 10.7+, 
+but severe issues with the libc++ version on 10.7.x keep it from running reliably. 
+0.13.1 now requires 10.8+, and will communicate that to 10.7 users, rather than crashing unexpectedly.
+
+Notable changes
+===============
+
+Segregated witness soft fork
+----------------------------
+
+Segregated witness (segwit) is a soft fork that, if activated, will
+allow transaction-producing software to separate (segregate) transaction
+signatures (witnesses) from the part of the data in a transaction that is
+covered by the txid. This provides several immediate benefits:
+
+- **Elimination of unwanted transaction malleability:** Segregating the witness
+  allows both existing and upgraded software to calculate the transaction
+  identifier (txid) of transactions without referencing the witness, which can
+  sometimes be changed by third-parties (such as miners) or by co-signers in a
+  multisig spend. This solves all known cases of unwanted transaction
+  malleability, which is a problem that makes programming Bitcoin wallet
+  software more difficult and which seriously complicates the design of smart
+  contracts for Bitcoin.
+
+- **Capacity increase:** Segwit transactions contain new fields that are not
+  part of the data currently used to calculate the size of a block, which
+  allows a block containing segwit transactions to hold more data than allowed
+  by the current maximum block size. Estimates based on the transactions
+  currently found in blocks indicate that if all wallets switch to using
+  segwit, the network will be able to support about 70% more transactions. The
+  network will also be able to support more of the advanced-style payments
+  (such as multisig) than it can support now because of the different weighting
+  given to different parts of a transaction after segwit activates (see the
+  following section for details).
+
+- **Weighting data based on how it affects node performance:** Some parts of
+  each Bitcoin block need to be stored by nodes in order to validate future
+  blocks; other parts of a block can be immediately forgotten (pruned) or used
+  only for helping other nodes sync their copy of the block chain.  One large
+  part of the immediately prunable data are transaction signatures (witnesses),
+  and segwit makes it possible to give a different "weight" to segregated
+  witnesses to correspond with the lower demands they place on node resources.
+  Specifically, each byte of a segregated witness is given a weight of 1, each
+  other byte in a block is given a weight of 4, and the maximum allowed weight
+  of a block is 4 million.  Weighting the data this way better aligns the most
+  profitable strategy for creating blocks with the long-term costs of block
+  validation.
+
+- **Signature covers value:** A simple improvement in the way signatures are
+  generated in segwit simplifies the design of secure signature generators
+  (such as hardware wallets), reduces the amount of data the signature
+  generator needs to download, and allows the signature generator to operate
+  more quickly.  This is made possible by having the generator sign the amount
+  of bitcoins they think they are spending, and by having full nodes refuse to
+  accept those signatures unless the amount of bitcoins being spent is exactly
+  the same as was signed.  For non-segwit transactions, wallets instead had to
+  download the complete previous transactions being spent for every payment
+  they made, which could be a slow operation on hardware wallets and in other
+  situations where bandwidth or computation speed was constrained.
+
+- **Linear scaling of sighash operations:** In 2015 a block was produced that
+  required about 25 seconds to validate on modern hardware because of the way
+  transaction signature hashes are performed.  Other similar blocks, or blocks
+  that could take even longer to validate, can still be produced today.  The
+  problem that caused this can't be fixed in a soft fork without unwanted
+  side-effects, but transactions that opt-in to using segwit will now use a
+  different signature method that doesn't suffer from this problem and doesn't
+  have any unwanted side-effects.
+
+- **Increased security for multisig:** Bitcoin addresses (both P2PKH addresses
+  that start with a '1' and P2SH addresses that start with a '3') use a hash
+  function known as RIPEMD-160.  For P2PKH addresses, this provides about 160
+  bits of security---which is beyond what cryptographers believe can be broken
+  today.  But because P2SH is more flexible, only about 80 bits of security is
+  provided per address. Although 80 bits is very strong security, it is within
+  the realm of possibility that it can be broken by a powerful adversary.
+  Segwit allows advanced transactions to use the SHA256 hash function instead,
+  which provides about 128 bits of security  (that is 281 trillion times as
+  much security as 80 bits and is equivalent to the maximum bits of security
+  believed to be provided by Bitcoin's choice of parameters for its Elliptic
+  Curve Digital Security Algorithm [ECDSA].)
+
+- **More efficient almost-full-node security** Satoshi Nakamoto's original
+  Bitcoin paper describes a method for allowing newly-started full nodes to
+  skip downloading and validating some data from historic blocks that are
+  protected by large amounts of proof of work.  Unfortunately, Nakamoto's
+  method can't guarantee that a newly-started node using this method will
+  produce an accurate copy of Bitcoin's current ledger (called the UTXO set),
+  making the node vulnerable to falling out of consensus with other nodes.
+  Although the problems with Nakamoto's method can't be fixed in a soft fork,
+  Segwit accomplishes something similar to his original proposal: it makes it
+  possible for a node to optionally skip downloading some blockchain data
+  (specifically, the segregated witnesses) while still ensuring that the node
+  can build an accurate copy of the UTXO set for the block chain with the most
+  proof of work.  Segwit enables this capability at the consensus layer, but
+  note that Bitcoin Core does not provide an option to use this capability as
+  of this 0.13.1 release.
+
+- **Script versioning:** Segwit makes it easy for future soft forks to allow
+  Bitcoin users to individually opt-in to almost any change in the Bitcoin
+  Script language when those users receive new transactions.  Features
+  currently being researched by Bitcoin Core contributors that may use this
+  capability include support for Schnorr signatures, which can improve the
+  privacy and efficiency of multisig transactions (or transactions with
+  multiple inputs), and Merklized Abstract Syntax Trees (MAST), which can
+  improve the privacy and efficiency of scripts with two or more conditions.
+  Other Bitcoin community members are studying several other improvements
+  that can be made using script versioning.
+
+Activation for the segwit soft fork is being managed using BIP9
+versionbits.  Segwit's version bit is bit 1, and nodes will begin
+tracking which blocks signal support for segwit at the beginning of the
+first retarget period after segwit's start date of 15 November 2016.  If
+95% of blocks within a 2,016-block retarget period (about two weeks)
+signal support for segwit, the soft fork will be locked in.  After
+another 2,016 blocks, segwit will activate.
+
+For more information about segwit, please see the [segwit FAQ][], the
+[segwit wallet developers guide][] or BIPs [141][BIP141], [143][BIP143],
+[144][BIP144], and [145][BIP145].  If you're a miner or mining pool
+operator, please see the [versionbits FAQ][] for information about
+signaling support for a soft fork.

+
+
+Null dummy soft fork
+-------------------
+
+Combined with the segwit soft fork is an additional change that turns a
+long-existing network relay policy into a consensus rule. The
+`OP_CHECKMULTISIG` and `OP_CHECKMULTISIGVERIFY` opcodes consume an extra
+stack element ("dummy element") after signature validation. The dummy
+element is not inspected in any manner, and could be replaced by any
+value without invalidating the script.
+
+Because any value can be used for this dummy element, it's possible for
+a third-party to insert data into other people's transactions, changing
+the transaction's txid (called transaction malleability) and possibly
+causing other problems.
+
+Since Bitcoin Core 0.10.0, nodes have defaulted to only relaying and
+mining transactions whose dummy element was a null value (0x00, also
+called OP_0).  The null dummy soft fork turns this relay rule into a
+consensus rule both for non-segwit transactions and segwit transactions,
+so that this method of mutating transactions is permanently eliminated
+from the network.
+
+Signaling for the null dummy soft fork is done by signaling support
+for segwit, and the null dummy soft fork will activate at the same time
+as segwit.
+
+For more information, please see [BIP147][].
+
+[BIP147]: https://github.com/bitcoin/bips/blob/master/bip-0147.mediawiki
+
+Low-level RPC changes
+---------------------
+
+- `importprunedfunds` only accepts two required arguments. Some versions accept
+  an optional third arg, which was always ignored. Make sure to never pass more
+  than two arguments.
+
+
+Linux ARM builds
+----------------
+
+With the 0.13.0 release, pre-built Linux ARM binaries were added to the set of
+uploaded executables. Additional detail on the ARM architecture targeted by each
+is provided below.
+
+The following extra files can be found in the download directory or torrent:
+
+- `bitcoin-${VERSION}-arm-linux-gnueabihf.tar.gz`: Linux binaries targeting
+  the 32-bit ARMv7-A architecture.
+- `bitcoin-${VERSION}-aarch64-linux-gnu.tar.gz`: Linux binaries targeting
+  the 64-bit ARMv8-A architecture.
+
+ARM builds are still experimental. If you have problems on a certain device or
+Linux distribution combination please report them on the bug tracker, it may be
+possible to resolve them. Note that the device you use must be (backward)
+compatible with the architecture targeted by the binary that you use.
+For example, a Raspberry Pi 2 Model B or Raspberry Pi 3 Model B (in its 32-bit
+execution state) device, can run the 32-bit ARMv7-A targeted binary. However,
+no model of Raspberry Pi 1 device can run either binary because they are all
+ARMv6 architecture devices that are not compatible with ARMv7-A or ARMv8-A.
+
+Note that Android is not considered ARM Linux in this context. The executables
+are not expected to work out of the box on Android.

+Bitcoin Core version 0.13.2 is now available from:

+
+Compatibility
+==============
+
+Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support),
+an OS initially released in 2001. This means that not even critical security
+updates will be released anymore. Without security updates, using a bitcoin
+wallet on a XP machine is irresponsible at least.
+
+In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
+randomly crashing on Windows XP. It is [not clear](https://github.com/bitcoin/bitcoin/issues/7681#issuecomment-217439891)
+what the source of these crashes is, but it is likely that upstream
+libraries such as Qt are no longer being tested on XP.
+
+We do not have time nor resources to provide support for an OS that is
+end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are
+suggested to upgrade to a newer version of Windows, or install an alternative OS
+that is supported.
+
+No attempt is made to prevent installing or running the software on Windows XP,
+you can still do so at your own risk, but do not expect it to work: do not
+report issues about Windows XP to the issue tracker.
+
+From 0.13.1 onwards OS X 10.7 is no longer supported. 0.13.0 was intended to work on 10.7+, 
+but severe issues with the libc++ version on 10.7.x keep it from running reliably. 
+0.13.1 now requires 10.8+, and will communicate that to 10.7 users, rather than crashing unexpectedly.
+
+Notable changes
+===============
+
+Change to wallet handling of mempool rejection
+-----------------------------------------------
+
+When a newly created transaction failed to enter the mempool due to
+the limits on chains of unconfirmed transactions the sending RPC
+calls would return an error.  The transaction would still be queued
+in the wallet and, once some of the parent transactions were
+confirmed, broadcast after the software was restarted.
+
+This behavior has been changed to return success and to reattempt
+mempool insertion at the same time transaction rebroadcast is
+attempted, avoiding a need for a restart.
+
+Transactions in the wallet which cannot be accepted into the mempool
+can be abandoned with the previously existing abandontransaction RPC
+(or in the GUI via a context menu on the transaction).
+
+

+
+Compatibility
+==============
+
+Bitcoin Core is extensively tested on multiple operating systems using
+the Linux kernel, macOS 10.8+, and Windows Vista and later.
+
+Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support),
+No attempt is made to prevent installing or running the software on Windows XP, you
+can still do so at your own risk but be aware that there are known instabilities and issues.
+Please do not report issues about Windows XP to the issue tracker.
+
+Bitcoin Core should also work on most other Unix-like systems but is not
+frequently tested on them.
+
+Notable changes
+===============
+
+Performance Improvements
+--------------
+
+Validation speed and network propagation performance have been greatly
+improved, leading to much shorter sync and initial block download times.
+
+- The script signature cache has been reimplemented as a "cuckoo cache",
+  allowing for more signatures to be cached and faster lookups.
+- Assumed-valid blocks have been introduced which allows script validation to
+  be skipped for ancestors of known-good blocks, without changing the security
+  model. See below for more details.
+- In some cases, compact blocks are now relayed before being fully validated as
+  per BIP152.
+- P2P networking has been refactored with a focus on concurrency and
+  throughput. Network operations are no longer bottlenecked by validation. As a
+  result, block fetching is several times faster than previous releases in many
+  cases.
+- The UTXO cache now claims unused mempool memory. This speeds up initial block
+  download as UTXO lookups are a major bottleneck there, and there is no use for
+  the mempool at that stage.
+
+
+Manual Pruning
+--------------
+
+Bitcoin Core has supported automatically pruning the blockchain since 0.11. Pruning
+the blockchain allows for significant storage space savings as the vast majority of
+the downloaded data can be discarded after processing so very little of it remains
+on the disk.
+
+Manual block pruning can now be enabled by setting `-prune=1`. Once that is set,
+the RPC command `pruneblockchain` can be used to prune the blockchain up to the
+specified height or timestamp.
+
+`getinfo` Deprecated
+--------------------
+
+The `getinfo` RPC command has been deprecated. Each field in the RPC call
+has been moved to another command's output with that command also giving
+additional information that `getinfo` did not provide. The following table
+shows where each field has been moved to:
+
+|`getinfo` field   | Moved to                                  |
+|------------------|-------------------------------------------|
+`"version"`	   | `getnetworkinfo()["version"]`
+`"protocolversion"`| `getnetworkinfo()["protocolversion"]`
+`"walletversion"`  | `getwalletinfo()["walletversion"]`
+`"balance"`	   | `getwalletinfo()["balance"]`
+`"blocks"`	   | `getblockchaininfo()["blocks"]`
+`"timeoffset"`	   | `getnetworkinfo()["timeoffset"]`
+`"connections"`	   | `getnetworkinfo()["connections"]`
+`"proxy"`	   | `getnetworkinfo()["networks"][0]["proxy"]`
+`"difficulty"`	   | `getblockchaininfo()["difficulty"]`
+`"testnet"`	   | `getblockchaininfo()["chain"] == "test"`
+`"keypoololdest"`  | `getwalletinfo()["keypoololdest"]`
+`"keypoolsize"`	   | `getwalletinfo()["keypoolsize"]`
+`"unlocked_until"` | `getwalletinfo()["unlocked_until"]`
+`"paytxfee"`	   | `getwalletinfo()["paytxfee"]`
+`"relayfee"`	   | `getnetworkinfo()["relayfee"]`
+`"errors"`	   | `getnetworkinfo()["warnings"]`
+
+ZMQ On Windows
+--------------
+
+Previously the ZeroMQ notification system was unavailable on Windows
+due to various issues with ZMQ. These have been fixed upstream and
+now ZMQ can be used on Windows. Please see [this document](https://github.com/bitcoin/bitcoin/blob/master/doc/zmq.md) for
+help with using ZMQ in general.
+
+Nested RPC Commands in Debug Console
+------------------------------------
+
+The ability to nest RPC commands has been added to the debug console. This
+allows users to have the output of a command become the input to another
+command without running the commands separately.
+
+The nested RPC commands use bracket syntax (i.e. `getwalletinfo()`) and can
+be nested (i.e. `getblock(getblockhash(1))`). Simple queries can be
+done with square brackets where object values are accessed with either an 
+array index or a non-quoted string (i.e. `listunspent()[0][txid]`). Both
+commas and spaces can be used to separate parameters in both the bracket syntax
+and normal RPC command syntax.
+
+Network Activity Toggle
+-----------------------
+
+A RPC command and GUI toggle have been added to enable or disable all p2p
+network activity. The network status icon in the bottom right hand corner 
+is now the GUI toggle. Clicking the icon will either enable or disable all
+p2p network activity. If network activity is disabled, the icon will 
+be grayed out with an X on top of it.
+
+Additionally the `setnetworkactive` RPC command has been added which does
+the same thing as the GUI icon. The command takes one boolean parameter,
+`true` enables networking and `false` disables it.
+
+Out-of-sync Modal Info Layer
+----------------------------
+
+When Bitcoin Core is out-of-sync on startup, a semi-transparent information
+layer will be shown over top of the normal display. This layer contains
+details about the current sync progress and estimates the amount of time
+remaining to finish syncing. This layer can also be hidden and subsequently
+unhidden by clicking on the progress bar at the bottom of the window.
+
+Support for JSON-RPC Named Arguments
+------------------------------------
+
+Commands sent over the JSON-RPC interface and through the `bitcoin-cli` binary
+can now use named arguments. This follows the [JSON-RPC specification](http://www.jsonrpc.org/specification)
+for passing parameters by-name with an object.
+
+`bitcoin-cli` has been updated to support this by parsing `name=value` arguments
+when the `-named` option is given.
+
+Some examples:
+
+    src/bitcoin-cli -named help command="help"
+    src/bitcoin-cli -named getblockhash height=0
+    src/bitcoin-cli -named getblock blockhash=000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f
+    src/bitcoin-cli -named sendtoaddress address="(snip)" amount="1.0" subtractfeefromamount=true
+
+The order of arguments doesn't matter in this case. Named arguments are also
+useful to leave out arguments that should stay at their default value. The
+rarely-used arguments `comment` and `comment_to` to `sendtoaddress`, for example, can
+be left out. However, this is not yet implemented for many RPC calls, this is
+expected to land in a later release.
+
+The RPC server remains fully backwards compatible with positional arguments.
+
+Opt into RBF When Sending
+-------------------------
+
+A new startup option, `-walletrbf`, has been added to allow users to have all
+transactions sent opt into RBF support. The default value for this option is
+currently `false`, so transactions will not opt into RBF by default. The new
+`bumpfee` RPC can be used to replace transactions that opt into RBF.
+
+Sensitive Data Is No Longer Stored In Debug Console History
+-----------------------------------------------------------
+
+The debug console maintains a history of previously entered commands that can be
+accessed by pressing the Up-arrow key so that users can easily reuse previously
+entered commands. Commands which have sensitive information such as passphrases and
+private keys will now have a `(...)` in place of the parameters when accessed through
+the history.
+
+Retaining the Mempool Across Restarts
+-------------------------------------
+
+The mempool will be saved to the data directory prior to shutdown
+to a `mempool.dat` file. This file preserves the mempool so that when the node
+restarts the mempool can be filled with transactions without waiting for new transactions
+to be created. This will also preserve any changes made to a transaction through
+commands such as `prioritisetransaction` so that those changes will not be lost.
+
+Final Alert
+-----------
+
+The Alert System was [disabled and deprecated](https://bitcoin.org/en/alert/2016-11-01-alert-retirement) in Bitcoin Core 0.12.1 and removed in 0.13.0. 
+The Alert System was retired with a maximum sequence final alert which causes any nodes
+supporting the Alert System to display a static hard-coded "Alert Key Compromised" message which also
+prevents any other alerts from overriding it. This final alert is hard-coded into this release
+so that all old nodes receive the final alert.
+
+GUI Changes
+-----------
+
+ - After resetting the options by clicking the `Reset Options` button 
+   in the options dialog or with the `-resetguioptions` startup option, 
+   the user will be prompted to choose the data directory again. This 
+   is to ensure that custom data directories will be kept after the 
+   option reset which clears the custom data directory set via the choose 
+   datadir dialog.
+
+ - Multiple peers can now be selected in the list of peers in the debug 
+   window. This allows for users to ban or disconnect multiple peers 
+   simultaneously instead of banning them one at a time.
+
+ - An indicator has been added to the bottom right hand corner of the main
+   window to indicate whether the wallet being used is a HD wallet. This
+   icon will be grayed out with an X on top of it if the wallet is not a
+   HD wallet.
+
+Low-level RPC changes
+----------------------
+
+ - `importprunedfunds` only accepts two required arguments. Some versions accept
+   an optional third arg, which was always ignored. Make sure to never pass more
+   than two arguments.
+
+ - The first boolean argument to `getaddednodeinfo` has been removed. This is 
+   an incompatible change.
+
+ - RPC command `getmininginfo` loses the "testnet" field in favor of the more
+   generic "chain" (which has been present for years).
+
+ - A new RPC command `preciousblock` has been added which marks a block as
+   precious. A precious block will be treated as if it were received earlier
+   than a competing block.
+
+ - A new RPC command `importmulti` has been added which receives an array of 
+   JSON objects representing the intention of importing a public key, a 
+   private key, an address and script/p2sh
+
+ - Use of `getrawtransaction` for retrieving confirmed transactions with unspent
+   outputs has been deprecated. For now this will still work, but in the future
+   it may change to only be able to retrieve information about transactions in
+   the mempool or if `txindex` is enabled.
+
+ - A new RPC command `getmemoryinfo` has been added which will return information
+   about the memory usage of Bitcoin Core. This was added in conjunction with
+   optimizations to memory management. See [Pull #8753](https://github.com/bitcoin/bitcoin/pull/8753)
+   for more information.
+
+ - A new RPC command `bumpfee` has been added which allows replacing an
+   unconfirmed wallet transaction that signaled RBF (see the `-walletrbf`
+   startup option above) with a new transaction that pays a higher fee, and
+   should be more likely to get confirmed quickly.
+
+HTTP REST Changes
+-----------------
+
+ - UTXO set query (`GET /rest/getutxos/<checkmempool>/<txid>-<n>/<txid>-<n>
+   /.../<txid>-<n>.<bin|hex|json>`) responses were changed to return status 
+   code `HTTP_BAD_REQUEST` (400) instead of `HTTP_INTERNAL_SERVER_ERROR` (500)
+   when requests contain invalid parameters.
+
+Minimum Fee Rate Policies
+-------------------------
+
+Since the changes in 0.12 to automatically limit the size of the mempool and improve the performance of block creation in mining code it has not been important for relay nodes or miners to set `-minrelaytxfee`. With this release the following concepts that were tied to this option have been separated out:
+- incremental relay fee used for calculating BIP 125 replacement and mempool limiting. (1000 satoshis/kB)
+- calculation of threshold for a dust output. (effectively 3 * 1000 satoshis/kB)
+- minimum fee rate of a package of transactions to be included in a block created by the mining code. If miners wish to set this minimum they can use the new `-blockmintxfee` option.  (defaults to 1000 satoshis/kB)
+
+The `-minrelaytxfee` option continues to exist but is recommended to be left unset.
+
+Fee Estimation Changes
+----------------------
+
+- Since 0.13.2 fee estimation for a confirmation target of 1 block has been
+  disabled. The fee slider will no longer be able to choose a target of 1 block.
+  This is only a minor behavior change as there was often insufficient
+  data for this target anyway. `estimatefee 1` will now always return -1 and
+  `estimatesmartfee 1` will start searching at a target of 2.
+
+- The default target for fee estimation is changed to 6 blocks in both the GUI
+  (previously 25) and for RPC calls (previously 2).
+
+Removal of Priority Estimation
+------------------------------
+
+- Estimation of "priority" needed for a transaction to be included within a target
+  number of blocks has been removed.  The RPC calls are deprecated and will either
+  return -1 or 1e24 appropriately. The format for `fee_estimates.dat` has also
+  changed to no longer save these priority estimates. It will automatically be
+  converted to the new format which is not readable by prior versions of the
+  software.
+
+- Support for "priority" (coin age) transaction sorting for mining is
+  considered deprecated in Core and will be removed in the next major version.
+  This is not to be confused with the `prioritisetransaction` RPC which will remain
+  supported by Core for adding fee deltas to transactions.
+
+P2P connection management
+--------------------------
+
+- Peers manually added through the `-addnode` option or `addnode` RPC now have their own
+  limit of eight connections which does not compete with other inbound or outbound
+  connection usage and is not subject to the limitation imposed by the `-maxconnections`
+  option.
+
+- New connections to manually added peers are performed more quickly.
+
+Introduction of assumed-valid blocks
+-------------------------------------
+
+- A significant portion of the initial block download time is spent verifying
+  scripts/signatures.  Although the verification must pass to ensure the security
+  of the system, no other result from this verification is needed: If the node
+  knew the history of a given block were valid it could skip checking scripts
+  for its ancestors.
+
+- A new configuration option 'assumevalid' is provided to express this knowledge
+  to the software.  Unlike the 'checkpoints' in the past this setting does not
+  force the use of a particular chain: chains that are consistent with it are
+  processed quicker, but other chains are still accepted if they'd otherwise
+  be chosen as best. Also unlike 'checkpoints' the user can configure which
+  block history is assumed true, this means that even outdated software can
+  sync more quickly if the setting is updated by the user.
+
+- Because the validity of a chain history is a simple objective fact it is much
+  easier to review this setting.  As a result the software ships with a default
+  value adjusted to match the current chain shortly before release.  The use
+  of this default value can be disabled by setting -assumevalid=0
+
+Fundrawtransaction change address reuse
+----------------------------------------
+
+- Before 0.14, `fundrawtransaction` was by default wallet stateless. In
+  almost all cases `fundrawtransaction` does add a change-output to the
+  outputs of the funded transaction. Before 0.14, the used keypool key was
+  never marked as change-address key and directly returned to the keypool
+  (leading to address reuse).  Before 0.14, calling `getnewaddress`
+  directly after `fundrawtransaction` did generate the same address as
+  the change-output address.
+
+- Since 0.14, fundrawtransaction does reserve the change-output-key from
+  the keypool by default (optional by setting  `reserveChangeKey`, default =
+  `true`)
+
+- Users should also consider using `getrawchangeaddress()` in conjunction
+  with `fundrawtransaction`'s `changeAddress` option.
+
+Unused mempool memory used by coincache
+----------------------------------------
+
+- Before 0.14, memory reserved for mempool (using the `-maxmempool` option)
+  went unused during initial block download, or IBD. In 0.14, the UTXO DB cache
+  (controlled with the `-dbcache` option) borrows memory from the mempool
+  when there is extra memory available. This may result in an increase in
+  memory usage during IBD for those previously relying on only the `-dbcache`
+  option to limit memory during that time.

+Bitcoin Core version 0.14.1 is now available from:
+
+  <https://bitcoin.org/bin/bitcoin-core-0.14.1/>
+
+This is a new minor version release, including various bugfixes and
+performance improvements, as well as updated translations.
+
+Please report bugs using the issue tracker at github:
+
+  <https://github.com/bitcoin/bitcoin/issues>
+
+To receive security and update notifications, please subscribe to:
+
+  <https://bitcoincore.org/en/list/announcements/join/>
+
+Compatibility
+==============
+
+Bitcoin Core is extensively tested on multiple operating systems using
+the Linux kernel, macOS 10.8+, and Windows Vista and later.
+
+Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support),
+No attempt is made to prevent installing or running the software on Windows XP, you
+can still do so at your own risk but be aware that there are known instabilities and issues.
+Please do not report issues about Windows XP to the issue tracker.
+
+Bitcoin Core should also work on most other Unix-like systems but is not
+frequently tested on them.
+
+Notable changes
+===============
+
+RPC changes
+-----------
+
+- The first positional argument of `createrawtransaction` was renamed from
+  `transactions` to `inputs`.
+
+- The argument of `disconnectnode` was renamed from `node` to `address`.
+
+These interface changes break compatibility with 0.14.0, when the named
+arguments functionality, introduced in 0.14.0, is used. Client software
+using these calls with named arguments needs to be updated.
+
+Mining
+------
+
+In previous versions, getblocktemplate required segwit support from downstream
+clients/miners once the feature activated on the network. In this version, it
+now supports non-segwit clients even after activation, by removing all segwit
+transactions from the returned block template. This allows non-segwit miners to
+continue functioning correctly even after segwit has activated.
+
+Due to the limitations in previous versions, getblocktemplate also recommended
+non-segwit clients to not signal for the segwit version-bit. Since this is no
+longer an issue, getblocktemplate now always recommends signalling segwit for
+all miners. This is safe because ability to enforce the rule is the only
+required criteria for safe activation, not actually producing segwit-enabled
+blocks.
+
+UTXO memory accounting
+----------------------
+
+Memory usage for the UTXO cache is being calculated more accurately, so that
+the configured limit (`-dbcache`) will be respected when memory usage peaks
+during cache flushes.  The memory accounting in prior releases is estimated to
+only account for half the actual peak utilization.
+
+The default `-dbcache` has also been changed in this release to 450MiB.  Users
+who currently set `-dbcache` to a high value (e.g. to keep the UTXO more fully
+cached in memory) should consider increasing this setting in order to achieve
+the same cache performance as prior releases.  Users on low-memory systems
+(such as systems with 1GB or less) should consider specifying a lower value for
+this parameter.
+
+Additional information relating to running on low-memory systems can be found
+here:
+[reducing-bitcoind-memory-usage.md](https://gist.github.com/laanwj/efe29c7661ce9b6620a7).

-leveldb: A key-value store
-Authors: Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
-
-The code under this directory implements a system for maintaining a
-persistent key/value store.
-
-See doc/index.html for more explanation.
-See doc/impl.html for a brief overview of the implementation.
-
-The public interface is in include/*.h.  Callers should not include or
-rely on the details of any other header files in this package.  Those
-internal APIs may be changed without warning.
-
-Guide to header files:
-
-include/db.h
-    Main interface to the DB: Start here
-
-include/options.h
-    Control over the behavior of an entire database, and also
-    control over the behavior of individual reads and writes.
-
-include/comparator.h
-    Abstraction for user-specified comparison function.  If you want
-    just bytewise comparison of keys, you can use the default comparator,
-    but clients can write their own comparator implementations if they
-    want custom ordering (e.g. to handle different character
-    encodings, etc.)
-
-include/iterator.h
-    Interface for iterating over data. You can get an iterator
-    from a DB object.
-
-include/write_batch.h
-    Interface for atomically applying multiple updates to a database.
-
-include/slice.h
-    A simple module for maintaining a pointer and a length into some
-    other byte array.
-
-include/status.h
-    Status is returned from many of the public interfaces and is used
-    to report success and various kinds of errors.
-
-include/env.h
-    Abstraction of the OS environment.  A posix implementation of
-    this interface is in util/env_posix.cc
-
-include/table.h
-include/table_builder.h
-    Lower-level modules that most clients probably won't use directly

   * Only a single process (possibly multi-threaded) can access a particular database at a time.

+# Contributing to the leveldb Project
+The leveldb project welcomes contributions. leveldb's primary goal is to be
+a reliable and fast key/value store. Changes that are in line with the
+features/limitations outlined above, and meet the requirements below,
+will be considered.
+
+Contribution requirements:
+
+1. **POSIX only**. We _generally_ will only accept changes that are both
+   compiled, and tested on a POSIX platform - usually Linux. Very small
+   changes will sometimes be accepted, but consider that more of an
+   exception than the rule.
+
+2. **Stable API**. We strive very hard to maintain a stable API. Changes that
+   require changes for projects using leveldb _might_ be rejected without
+   sufficient benefit to the project.
+
+3. **Tests**: All changes must be accompanied by a new (or changed) test, or
+   a sufficient explanation as to why a new (or changed) test is not required.
+
+## Submitting a Pull Request
+Before any pull request will be accepted the author must first sign a
+Contributor License Agreement (CLA) at https://cla.developers.google.com/.
+
+In order to keep the commit timeline linear
+[squash](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History#Squashing-Commits)
+your changes down to a single commit and [rebase](https://git-scm.com/docs/git-rebase)
+on google/leveldb/master. This keeps the commit timeline linear and more easily sync'ed
+with the internal repository at Google. More information at GitHub's
+[About Git rebase](https://help.github.com/articles/about-git-rebase/) page.

  * sufficiently high percentage of them were confirmed within 5 blocks and

  * within your desired 5 blocks.
  *
- * When a transaction enters the mempool or is included within a block we

  * paid in each bucket. Then we calculate how many blocks Y it took each
  * transaction to be mined and we track an array of counters in each bucket
  * for how long it to took transactions to get confirmed from 1 to a max of 25
  * and we increment all the counters from Y up to 25. This is because for any
  * number Z>=Y the transaction was successfully mined within Z blocks.  We
  * want to save a history of this information, so at any time we have a
- * counter of the total number of transactions that happened in a given fee
+ * counter of the total number of transactions that happened in a given feerate
  * bucket and the total number that were confirmed in each number 1-25 blocks
  * or less for any bucket.   We save this history by keeping an exponentially
  * decaying moving average of each one of these stats.  Furthermore we also
  * keep track of the number unmined (in mempool) transactions in each bucket
  * and for how many blocks they have been outstanding and use that to increase
- * the number of transactions we've seen in that fee bucket when calculating

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>Генерираните монети трябва да отлежат %1 блока преди да могат да бъдат похарчени. Когато генерираш блока, той се разпространява в мрежата, за да се добави в блок-веригата. Ако не успее да се добави във веригата, неговия статус  ще се стане "неприет" и няма да може да се похарчи. Това е възможно да се случи случайно, ако друг възел генерира блок няколко секунди след твоя.</translation>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>Les monedes generades han de madurar %1 blocs abans de poder ser gastades. Quan genereu aquest bloc, es farà saber a la xarxa per tal d'afegir-lo a la cadena de blocs. Si no pot fer-se lloc a la cadena, el seu estat canviarà a «no acceptat» i no es podrà gastar. Això pot passar ocasionalment si un altre node genera un bloc en un marge de segons respecte al vostre.</translation>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>Les monedes generades han de madurar %1 blocs abans de poder ser gastades. Quan genereu este bloc, es farà saber a la xarxa per tal d'afegir-lo a la cadena de blocs. Si no pot fer-se lloc a la cadena, el seu estat canviarà a «no acceptat» i no es podrà gastar. Això pot passar ocasionalment si un altre node genera un bloc en un marge de segons respecte al vostre.</translation>

This may occasionally happen if another node generates a block within a few seconds of yours.</source>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>Vygenerované mince musí čekat %1 bloků, než mohou být utraceny. Když jsi vygeneroval tenhle blok, tak byl rozposlán do sítě, aby byl přidán do řetězce bloků. Pokud se mu nepodaří dostat se do řetězce, změní se na „neakceptovaný“ a nepůjde utratit. To se občas může stát, pokud jiný uzel vygeneruje blok zhruba ve stejném okamžiku jako ty.</translation>

Dette kan ske nu og da, hvis en anden knude udvinder en blok inden for nogle få sekunder fra din.</translation>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>Erzeugte Bitcoins müssen %1 Blöcke lang reifen, bevor sie ausgegeben werden können. Als Sie diesen Block erzeugten, wurde er an das Netzwerk übertragen, um ihn der Blockkette hinzuzufügen. Falls dies fehlschlägt wird der Status in "nicht angenommen" geändert und Sie werden keine Bitcoins gutgeschrieben bekommen. Das kann gelegentlich passieren, wenn ein anderer Knoten einen Block fast zeitgleich erzeugt.</translation>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to &quot;not accepted&quot; and it won&apos;t be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>生成されたコインは使う前に%1のブロックを完成させる必要があります。あなたが生成した時、このブロックはブロック チェーンに追加されるネットワークにブロードキャストされました。チェーンに追加されるのが失敗した場合、状態が"不承認"に変更されて使えなくなるでしょう。これは、別のノードがあなたの数秒前にブロックを生成する場合に時々起こるかもしれません。</translation>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>Gegenereerde munten moeten %1 blokken rijpen voordat ze kunnen worden besteed. Toen dit blok gegenereerd werd, werd het uitgezonden naar het netwerk om aan de blokketen toegevoegd te worden. Als het niet lukt om in de keten toegevoegd te worden, zal de status te veranderen naar "niet geaccepteerd" en zal het niet besteedbaar zijn. Dit kan soms gebeuren als een ander knooppunt een blok genereert binnen een paar seconden na die van u.</translation>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>Moedas recém minerados precisam aguardar %1 blocos antes de serem gastos. Quando o bloco foi gerado, ele foi disseminado pela rede para ser adicionado à blockchain. Se ele falhar em ser inserido na cadeia, seu estado será modificado para "não aceito" e ele não poderá ser gasto. Isso pode acontecer eventualmente quando blocos são gerados quase que simultaneamente.</translation>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>Сгенерированные монеты должны подождать %1 блоков, прежде чем они могут быть потрачены. Когда вы сгенерировали этот блок, он был отправлен в сеть для добавления в цепочку блоков. Если он не попадёт в цепь, его статус изменится на "не принят", и монеты будут недействительны. Это иногда происходит в случае, если другой узел сгенерирует блок на несколько секунд раньше вас.</translation>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>Oluşturulan bitcoin'lerin harcanabilmelerinden önce %1 blok beklemeleri gerekmektedir. Bu blok, oluşturduğunuzda, blok zincirine eklenmesi için ağda yayınlandı. Zincire eklenmesi başarısız olursa, durumu "kabul edilmedi" olarak değiştirilecek ve harcanamayacaktır.

If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>

+        <source>Generated coins must mature %1 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to "not accepted" and it won't be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
+        <translation>生產出來的錢要再等 %1 個區塊生出來後才成熟可以用。當區塊生產出來時會公布到網路上，來被加進區塊鏈。如果加失敗了，狀態就會變成「不被接受」，而且不能夠花。如果在你生產出區塊的幾秒鐘內，也有其他節點生產出來的話，就有可能會發生這種情形。</translation>

+# SYNOPSIS
+#
+#   AX_JNI_INCLUDE_DIR
+#
+# DESCRIPTION
+#
+#   AX_JNI_INCLUDE_DIR finds include directories needed for compiling
+#   programs using the JNI interface.
+#
+#   JNI include directories are usually in the Java distribution. This is
+#   deduced from the value of $JAVA_HOME, $JAVAC, or the path to "javac", in
+#   that order. When this macro completes, a list of directories is left in
+#   the variable JNI_INCLUDE_DIRS.
+#
+#   Example usage follows:
+#
+#     AX_JNI_INCLUDE_DIR
+#
+#     for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
+#     do
+#             CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
+#     done
+#
+#   If you want to force a specific compiler:
+#
+#   - at the configure.in level, set JAVAC=yourcompiler before calling
+#   AX_JNI_INCLUDE_DIR
+#
+#   - at the configure level, setenv JAVAC
+#
+#   Note: This macro can work with the autoconf M4 macros for Java programs.
+#   This particular macro is not part of the original set of macros.

- * - All signers communicate their public nonces to each other (revealing your
- *   private nonce can lead to discovery of your private key, so it should be
- *   considered secret).
- * - All signers combine all the public nonces they received (excluding their
- *   own) using secp256k1_ec_pubkey_combine to obtain an
- *   Rall[i] = sum(R[0..i-1,i+1..n]).
- * - All signers produce a partial signature using
- *   secp256k1_schnorr_partial_sign, passing in their own private key x[i],
- *   their own private nonce k[i], and the sum of the others' public nonces
- *   Rall[i].
- * - All signers communicate their partial signatures to each other.
- * - Someone combines all partial signatures using
- *   secp256k1_schnorr_partial_combine, to obtain a full signature.
- * - The resulting signature is validatable using secp256k1_schnorr_verify, with
- *   public key equal to the result of secp256k1_ec_pubkey_combine of the

+# This code supports verifying group implementations which have branches
+# or conditional statements (like cmovs), by allowing each execution path
+# to independently set assumptions on input or intermediary variables.
+#
+# The general approach is:
+# * A constraint is a tuple of two sets of of symbolic expressions:
+#   the first of which are required to evaluate to zero, the second of which
+#   are required to evaluate to nonzero.
+#   - A constraint is said to be conflicting if any of its nonzero expressions
+#     is in the ideal with basis the zero expressions (in other words: when the
+#     zero expressions imply that one of the nonzero expressions are zero).
+# * There is a list of laws that describe the intended behaviour, including
+#   laws for addition and doubling. Each law is called with the symbolic point
+#   coordinates as arguments, and returns:
+#   - A constraint describing the assumptions under which it is applicable,
+#     called "assumeLaw"
+#   - A constraint describing the requirements of the law, called "require"
+# * Implementations are transliterated into functions that operate as well on
+#   algebraic input points, and are called once per combination of branches
+#   exectured. Each execution returns:
+#   - A constraint describing the assumptions this implementation requires
+#     (such as Z1=1), called "assumeFormula"
+#   - A constraint describing the assumptions this specific branch requires,
+#     but which is by construction guaranteed to cover the entire space by
+#     merging the results from all branches, called "assumeBranch"
+#   - The result of the computation
+# * All combinations of laws with implementation branches are tried, and:
+#   - If the combination of assumeLaw, assumeFormula, and assumeBranch results
+#     in a conflict, it means this law does not apply to this branch, and it is
+#     skipped.
+#   - For others, we try to prove the require constraints hold, assuming the
+#     information in assumeLaw + assumeFormula + assumeBranch, and if this does
+#     not succeed, we fail.
+#     + To prove an expression is zero, we check whether it belongs to the
+#       ideal with the assumed zero expressions as basis. This test is exact.
+#     + To prove an expression is nonzero, we check whether each of its
+#       factors is contained in the set of nonzero assumptions' factors.
+#       This test is not exact, so various combinations of original and
+#       reduced expressions' factors are tried.
+#   - If we succeed, we print out the assumptions from assumeFormula that
+#     weren't implied by assumeLaw already. Those from assumeBranch are skipped,
+#     as we assume that all constraints in it are complementary with each other.

-/**
- * Custom Schnorr-based signature scheme. They support multiparty signing, public key
- * recovery and batch validation.
- *
- * Rationale for verifying R's y coordinate:
- * In order to support batch validation and public key recovery, the full R point must
- * be known to verifiers, rather than just its x coordinate. In order to not risk
- * being more strict in batch validation than normal validation, validators must be
- * required to reject signatures with incorrect y coordinate. This is only possible
- * by including a (relatively slow) field inverse, or a field square root. However,
- * batch validation offers potentially much higher benefits than this cost.
- *
- * Rationale for having an implicit y coordinate oddness:
- * If we commit to having the full R point known to verifiers, there are two mechanism.
- * Either include its oddness in the signature, or give it an implicit fixed value.
- * As the R y coordinate can be flipped by a simple negation of the nonce, we choose the
- * latter, as it comes with nearly zero impact on signing or validation performance, and
- * saves a byte in the signature.
- *
- * Signing:
- *   Inputs: 32-byte message m, 32-byte scalar key x (!=0), 32-byte scalar nonce k (!=0)
- *
- *   Compute point R = k * G. Reject nonce if R's y coordinate is odd (or negate nonce).
- *   Compute 32-byte r, the serialization of R's x coordinate.
- *   Compute scalar h = Hash(r || m). Reject nonce if h == 0 or h >= order.
- *   Compute scalar s = k - h * x.
- *   The signature is (r, s).
- *
- *
- * Verification:
- *   Inputs: 32-byte message m, public key point Q, signature: (32-byte r, scalar s)
- *
- *   Signature is invalid if s >= order.
- *   Signature is invalid if r >= p.
- *   Compute scalar h = Hash(r || m). Signature is invalid if h == 0 or h >= order.
- *   Option 1 (faster for single verification):
- *     Compute point R = h * Q + s * G. Signature is invalid if R is infinity or R's y coordinate is odd.
- *     Signature is valid if the serialization of R's x coordinate equals r.
- *   Option 2 (allows batch validation and pubkey recovery):
- *     Decompress x coordinate r into point R, with odd y coordinate. Fail if R is not on the curve.
- *     Signature is valid if R + h * Q + s * G == 0.

- * Thread-safe class to keep track of locked (ie, non-swappable) memory pages.
- *
- * Memory locks do not stack, that is, pages which have been locked several times by calls to mlock()
- * will be unlocked by a single call to munlock(). This can result in keying material ending up in swap when
- * those functions are used naively. This class simulates stacking memory locks by keeping a counter per page.
- *
- * @note By using a map from each page base address to lock count, this class is optimized for
- * small objects that span up to a few pages, mostly smaller than a page. To support large allocations,
- * something like an interval tree would be the preferred data structure.

-The sources in this directory are unit test cases.  Boost includes a
-unit testing framework, and since bitcoin already uses boost, it makes
-sense to simply use this framework rather than require developers to
-configure some other framework (we want as few impediments to creating
-unit tests as possible).
+### Compiling/running unit tests
 
-The build system is setup to compile an executable called "test_bitcoin"
-that runs all of the unit tests.  The main source file is called
-test_bitcoin.cpp, which simply includes other files that contain the
-actual unit tests (outside of a couple required preprocessor
-directives).  The pattern is to create one test file for each class or
-source file for which you want to create unit tests.  The file naming
-convention is "<source_filename>_tests.cpp" and such files should wrap
-their tests in a test suite called "<source_filename>_tests".  For an
-examples of this pattern, examine uint160_tests.cpp and
-uint256_tests.cpp.
+Unit tests will be automatically compiled if dependencies were met in `./configure`
+and tests weren't explicitly disabled.
 
-Add the source files to /src/Makefile.test.include to add them to the build.
+After configuring, they can be run with `make check`.
 
-For further reading, I found the following website to be helpful in
-explaining how the boost unit test framework works:

+To run the bitcoind tests manually, launch `src/test/test_bitcoin`.
+
+To add more bitcoind tests, add `BOOST_AUTO_TEST_CASE` functions to the existing
+.cpp files in the `test/` directory or add new .cpp files that
+implement new BOOST_AUTO_TEST_SUITE sections.

+To run the bitcoin-qt tests manually, launch `src/qt/test/test_bitcoin-qt`

+ * - CWalletDBWrapper represents a wallet database (similar to CDBWrapper in dbwrapper.h)
+ * - CDB is a low-level database transaction (similar to CDBBatch in dbwrapper.h)
+ * - CWalletDB is a modifier object for the wallet, and encapsulates a database
+ *   transaction as well as methods to act on the database (no analog in
+ *   dbwrapper.h)
+ *
+ * The latter two are named confusingly, in contrast to what the names CDB
+ * and CWalletDB suggest they are transient transaction objects and don't

+This directory contains integration tests that test bitcoind and its
+utilities in their entirety. It does not contain unit tests, which
+can be found in [/src/test](/src/test), [/src/wallet/test](/src/wallet/test),
+etc.
+
+There are currently two sets of tests in this directory:
+
+- [functional](/test/functional) which test the functionality of 
+bitcoind and bitcoin-qt by interacting with them through the RPC and P2P
+interfaces.
+- [util](test/util) which tests the bitcoin utilities, currently only
+bitcoin-tx.
+
+The util tests are run as part of `make check` target. The functional
+tests are run by the travis continuous build process whenever a pull
+request is opened. Both sets of tests can also be run locally.
+
+Functional Test dependencies
+============================
+The ZMQ functional test requires a python ZMQ library. To install it:
+
+- on Unix, run `sudo apt-get install python3-zmq`
+- on mac OS, run `pip3 install pyzmq`
+
+Running tests locally
+=====================
+
+Build for your system first. Be sure to enable wallet, utils and daemon when you configure. Tests will not run otherwise.
+
+Functional tests
+----------------
+
+You can run any single test by calling
+
+    test/functional/test_runner.py <testname>
+
+Or you can run any combination (incl. duplicates) of tests by calling
+
+    test/functional/test_runner.py <testname1> <testname2> <testname3> ...
+
+Run the regression test suite with
+
+    test/functional/test_runner.py
+
+Run all possible tests with
+
+    test/functional/test_runner.py --extended
+
+By default, tests will be run in parallel. To specify how many jobs to run,
+append `--jobs=n` (default n=4).
+
+If you want to create a basic coverage report for the RPC test suite, append `--coverage`.
+
+Possible options, which apply to each individual test run:
+
+```
+  -h, --help            show this help message and exit
+  --nocleanup           Leave bitcoinds and test.* datadir on exit or error
+  --noshutdown          Don't stop bitcoinds after the test execution
+  --srcdir=SRCDIR       Source directory containing bitcoind/bitcoin-cli
+                        (default: ../../src)
+  --tmpdir=TMPDIR       Root directory for datadirs
+  --tracerpc            Print out all RPC calls as they are made
+  --coveragedir=COVERAGEDIR
+                        Write tested RPC commands into this directory
+```
+
+If you set the environment variable `PYTHON_DEBUG=1` you will get some debug
+output (example: `PYTHON_DEBUG=1 test/functional/test_runner.py wallet`).
+
+A 200-block -regtest blockchain and wallets for four nodes
+is created the first time a regression test is run and
+is stored in the cache/ directory. Each node has 25 mature
+blocks (25*50=1250 BTC) in its wallet.
+
+After the first run, the cache/ blockchain and wallets are
+copied into a temporary directory and used as the initial
+test state.
+
+If you get into a bad state, you should be able
+to recover with:
+
+```bash
+rm -rf cache
+killall bitcoind
+```
+
+Util tests
+----------
+
+Util tests can be run locally by running `test/util/bitcoin-util-test.py`. 
+Use the `-v` option for verbose output.
+
+Writing functional tests
+========================
+
+You are encouraged to write functional tests for new or existing features.
+Further information about the functional test framework and individual 
+tests is found in [test/functional](/test/functional).

+"""Test the abandontransaction RPC.
+
+ The abandontransaction RPC marks a transaction and all its in-wallet
+ descendants as abandoned which allows their inputs to be respent. It can be
+ used to replace "stuck" or evicted transactions. It only works on transactions
+ which are not included in a block and are not currently in the mempool. It has

+
+Test logic for skipping signature validation on blocks which we've assumed
+valid (https://github.com/bitcoin/bitcoin/pull/9484)
+
+We build a chain that includes and invalid signature for one of the
+transactions:
+
+    0:        genesis block
+    1:        block 1 with coinbase transaction output.
+    2-101:    bury that block with 100 blocks so the coinbase transaction
+              output can be spent
+    102:      a block containing a transaction spending the coinbase
+              transaction output. The transaction has an invalid signature.
+    103-2202: bury the bad block with just over two weeks' worth of blocks
+              (2100 blocks)
+
+Start three nodes:
+
+    - node0 has no -assumevalid parameter. Try to sync to block 2202. It will
+      reject block 102 and only sync as far as block 101
+    - node1 has -assumevalid set to the hash of block 102. Try to sync to
+      block 2202. node1 will sync all the way to block 2202.
+    - node2 has -assumevalid set to the hash of block 102. Try to sync to
+      block 200. node2 will reject block 102 since it's assumed valid, but it
+      isn't buried by at least two weeks' work.

+"""Test mempool persistence.
+
+By default, bitcoind will dump mempool on shutdown and
+then reload it on startup. This can be overridden with
+the -persistmempool=0 command line option.
+
+Test is as follows:
+
+  - start node0, node1 and node2. node1 has -persistmempool=0
+  - create 5 transactions on node2 to its own address. Note that these
+    are not sent to node0 or node1 addresses because we don't want
+    them to be saved in the wallet.
+  - check that node0 and node1 have 5 transactions in their mempools
+  - shutdown all nodes.
+  - startup node0. Verify that it still has 5 transactions
+    in its mempool. Shutdown node0. This tests that by default the
+    mempool is persistent.
+  - startup node1. Verify that its mempool is empty. Shutdown node1.
+    This tests that with -persistmempool=0, the mempool is not
+    dumped to disk when the node is shut down.
+  - Restart node0 with -persistmempool=0. Verify that its mempool is
+    empty. Shutdown node0. This tests that with -persistmempool=0,
+    the mempool is not loaded from disk on start up.
+  - Restart node0 with -persistmempool. Verify that it has 5
+    transactions in its mempool. This tests that -persistmempool=0
+    does not overwrite a previously valid mempool stored on disk.
