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> + +Miscellaneous +------------- + +The p2p alert system is off by default. To turn on, use `-alert` with +startup configuration. + +0.12.1 Change log +================= + +Detailed release notes follow.

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.

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 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. + +[Segwit FAQ]: https://bitcoincore.org/en/2016/01/26/segwit-benefits/ +[segwit wallet developers guide]: https://bitcoincore.org/en/segwit_wallet_dev/ +[BIP141]: https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki +[BIP143]: https://github.com/bitcoin/bips/blob/master/bip-0143.mediawiki +[BIP144]: https://github.com/bitcoin/bips/blob/master/bip-0144.mediawiki +[BIP145]: https://github.com/bitcoin/bips/blob/master/bip-0145.mediawiki +[versionbits FAQ]: https://bitcoincore.org/en/2016/06/08/version-bits-miners-faq/ + + +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. + + +0.13.1 Change log +================= + +Detailed release notes follow.

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). + + +0.13.2 Change log +================= + +Detailed release notes follow.

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. + +0.14.0 Change log +================= + +Detailed release notes follow. This overview includes changes that affect +behavior, not code moves, minor refactors and string updates.

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). + +0.14.1 Change log +================= + +Detailed release notes follow.
