+0.20.0 Release Notes
+====================
+
+Bitcoin Core version 0.20.0 is now available from:
+
+  <https://bitcoincore.org/bin/bitcoin-core-0.20.0/>
+
+This release includes new features, various bug fixes 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/>
+
+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 in some cases), then run the
+installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
+or `bitcoind`/`bitcoin-qt` (on Linux).
+
+Upgrading directly from a version of Bitcoin Core that has reached its EOL is
+possible, but it might take some time if the data directory needs to be migrated. Old
+wallet versions of Bitcoin Core are generally supported.
+
+Compatibility
+==============
+
+Bitcoin Core is supported and extensively tested on operating systems
+using the Linux kernel, macOS 10.12+, and Windows 7 and newer.  Bitcoin
+Core should also work on most other Unix-like systems but is not as
+frequently tested on them.  It is not recommended to use Bitcoin Core on
+unsupported systems.
+
+From Bitcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no
+longer supported. Additionally, Bitcoin Core does not yet change appearance
+when macOS "dark mode" is activated.
+
+Known Bugs
+==========
+
+The process for generating the source code release ("tarball") has changed in an
+effort to make it more complete, however, there are a few regressions in
+this release:
+
+- The generated `configure` script is currently missing, and you will need to
+  install autotools and run `./autogen.sh` before you can run
+  `./configure`. This is the same as when checking out from git.
+
+- Instead of running `make` simply, you should instead run
+  `BITCOIN_GENBUILD_NO_GIT=1 make`.
+
+Notable changes
+===============
+
+P2P and network changes
+-----------------------
+
+#### Removal of BIP61 reject network messages from Bitcoin Core
+
+The `-enablebip61` command line option to enable BIP61 has been removed.
+(#17004)
+
+This feature has been disabled by default since Bitcoin Core version 0.18.0.
+Nodes on the network can not generally be trusted to send valid messages
+(including reject messages), so this should only ever be used when
+connected to a trusted node.  Please use the alternatives recommended
+below if you rely on this removed feature:
+
+- Testing or debugging of implementations of the Bitcoin P2P network protocol
+  should be done by inspecting the log messages that are produced by a recent
+  version of Bitcoin Core. Bitcoin Core logs debug messages
+  (`-debug=<category>`) to a stream (`-printtoconsole`) or to a file
+  (`-debuglogfile=<debug.log>`).
+
+- Testing the validity of a block can be achieved by specific RPCs:
+
+  - `submitblock`
+
+  - `getblocktemplate` with `'mode'` set to `'proposal'` for blocks with
+    potentially invalid POW
+
+- Testing the validity of a transaction can be achieved by specific RPCs:
+
+  - `sendrawtransaction`
+
+  - `testmempoolaccept`
+
+- Wallets should not assume a transaction has propagated to the network
+  just because there are no reject messages.  Instead, listen for the
+  transaction to be announced by other peers on the network.  Wallets
+  should not assume a lack of reject messages means a transaction pays
+  an appropriate fee.  Instead, set fees using fee estimation and use
+  replace-by-fee to increase a transaction's fee if it hasn't confirmed
+  within the desired amount of time.
+
+The removal of BIP61 reject message support also has the following minor RPC
+and logging implications:
+
+- `testmempoolaccept` and `sendrawtransaction` no longer return the P2P reject
+  code when a transaction is not accepted to the mempool. They still return the
+  verbal reject reason.
+
+- Log messages that previously reported the reject code when a transaction was
+  not accepted to the mempool now no longer report the reject code. The reason
+  for rejection is still reported.
+
+Updated RPCs
+------------
+
+- The RPCs which accept descriptors now accept the new `sortedmulti(...)` descriptor
+  type which supports multisig scripts where the public keys are sorted
+  lexicographically in the resulting script.  (#17056)
+
+- The `walletprocesspsbt` and `walletcreatefundedpsbt` RPCs now include
+  BIP32 derivation paths by default for public keys if we know them.
+  This can be disabled by setting the `bip32derivs` parameter to
+  `false`.  (#17264)
+
+- The `bumpfee` RPC's parameter `totalFee`, which was deprecated in
+  0.19, has been removed.  (#18312)
+
+- The `bumpfee` RPC will return a PSBT when used with wallets that have
+  private keys disabled.  (#16373)
+
+- The `getpeerinfo` RPC now includes a `mapped_as` field to indicate the
+  mapped Autonomous System used for diversifying peer selection. See the
+  `-asmap` configuration option described below in _New Settings_.  (#16702)
+
+- The `createmultisig` and `addmultisigaddress` RPCs now return an
+  output script descriptor for the newly created address.  (#18032)
+
+Build System
+------------
+
+- OpenSSL is no longer used by Bitcoin Core.  (#17265)
+
+- BIP70 support has been fully removed from Bitcoin Core. The
+  `--enable-bip70` option remains, but it will throw an error during configure.
+  (#17165)
+
+- glibc 2.17 or greater is now required to run the release binaries. This
+  retains compatibility with RHEL 7, CentOS 7, Debian 8 and Ubuntu 14.04 LTS. (#17538)
+
+- The source code archives that are provided with gitian builds no longer contain
+  any autotools artifacts. Therefore, to build from such source, a user
+  should run the `./autogen.sh` script from the root of the unpacked archive.
+  This implies that `autotools` and other required packages are installed on the
+  user's system. (#18331)
+
+New settings
+------------
+
+- New `rpcwhitelist` and `rpcwhitelistdefault` configuration parameters
+  allow giving certain RPC users permissions to only some RPC calls.
+  (#12763)
+
+- A new `-asmap` configuration option has been added to diversify the
+  node's network connections by mapping IP addresses Autonomous System
+  Numbers (ASNs) and then limiting the number of connections made to any
+  single ASN.  See [issue #16599](https://github.com/bitcoin/bitcoin/issues/16599),
+  [PR #16702](https://github.com/bitcoin/bitcoin/pull/16702), and the
+  `bitcoind help` for more information.  This option is experimental and
+  subject to removal or breaking changes in future releases, so the
+  legacy /16 prefix mapping of IP addresses remains the default.  (#16702)
+
+Updated settings
+----------------
+
+- All custom settings configured when Bitcoin Core starts are now
+  written to the `debug.log` file to assist troubleshooting.  (#16115)
+
+- Importing blocks upon startup via the `bootstrap.dat` file no longer
+  occurs by default. The file must now be specified with
+  `-loadblock=<file>`.  (#17044)
+
+- The `-debug=db` logging category has been renamed to
+  `-debug=walletdb` to distinguish it from `coindb`.  The `-debug=db`
+  option has been deprecated and will be removed in the next major
+  release.  (#17410)
+
+- The `-walletnotify` configuration parameter will now replace any `%w`
+  in its argument with the name of the wallet generating the
+  notification.  This is not supported on Windows. (#13339)
+
+Removed settings
+----------------
+
+- The `-whitelistforcerelay` configuration parameter has been removed after
+  it was discovered that it was rendered ineffective in version 0.13 and
+  hasn't actually been supported for almost four years.  (#17985)
+
+GUI changes
+-----------
+
+- The "Start Bitcoin Core on system login" option has been removed on macOS.
+  (#17567)
+
+- In the Peers window, the details for a peer now displays a `Mapped AS`
+  field to indicate the mapped Autonomous System used for diversifying
+  peer selection. See the `-asmap` configuration option in _New
+  Settings_, above.  (#18402)
+
+- A "known bug" [announced](https://bitcoincore.org/en/releases/0.18.0/#wallet-gui)
+  in the release notes of version 0.18 has been fixed.  The issue
+  affected anyone who simultaneously used multiple Bitcoin Core wallets
+  and the GUI coin control feature. (#18894)
+
+- For watch-only wallets, creating a new transaction in the Send screen
+  or fee bumping an existing transaction in the Transactions screen will
+  automatically copy a Partially-Signed Bitcoin Transaction (PSBT) to
+  the system clipboard.  This can then be pasted into an external
+  program such as [HWI](https://github.com/bitcoin-core/HWI) for
+  signing.  Future versions of Bitcoin Core should support a GUI option
+  for finalizing and broadcasting PSBTs, but for now the debug console
+  may be used with the `finalizepsbt` and `sendrawtransaction` RPCs.
+  (#16944, #17492)
+
+Wallet
+------
+
+- The wallet now by default uses bech32 addresses when using RPC, and
+  creates native segwit change outputs.  (#16884)
+
+- The way that output trust was computed has been fixed, which affects
+  confirmed/unconfirmed balance status and coin selection.  (#16766)
+
+- The `gettransaction`, `listtransactions` and `listsinceblock` RPC
+  responses now also include the height of the block that contains the
+  wallet transaction, if any.  (#17437)
+
+- The `getaddressinfo` RPC has had its `label` field deprecated
+  (re-enable for this release using the configuration parameter
+  `-deprecatedrpc=label`).  The `labels` field is altered from returning
+  JSON objects to returning a JSON array of label names (re-enable
+  previous behavior for this release using the configuration parameter
+  `-deprecatedrpc=labelspurpose`).  Backwards compatibility using the
+  deprecated configuration parameters is expected to be dropped in the
+  0.21 release.  (#17585, #17578)
+
+Documentation changes
+---------------------
+
+- Bitcoin Core's automatically-generated source code documentation is
+  now available at https://doxygen.bitcoincore.org.  (#17596)
+
+Low-level changes
+=================
+
+Utilities
+---------
+
+- The `bitcoin-cli` utility used with the `-getinfo` parameter now
+  returns a `headers` field with the number of downloaded block headers
+  on the best headers chain (similar to the `blocks` field that is also
+  returned) and a `verificationprogress` field that estimates how much
+  of the best block chain has been synced by the local node.  The
+  information returned no longer includes the `protocolversion`,
+  `walletversion`, and `keypoololdest` fields.  (#17302, #17650)
+
+- The `bitcoin-cli` utility now accepts a `-stdinwalletpassphrase`
+  parameter that can be used when calling the `walletpassphrase` and
+  `walletpassphrasechange` RPCs to read the passphrase from standard
+  input without echoing it to the terminal, improving security against
+  anyone who can look at your screen.  The existing `-stdinrpcpass`
+  parameter is also updated to not echo the passphrase. (#13716)
+
+Command line
+------------
+
+- Command line options prefixed with main/test/regtest network names like
+  `-main.port=8333` `-test.server=1` previously were allowed but ignored. Now
+  they trigger "Invalid parameter" errors on startup. (#17482)
+
+New RPCs
+--------
+
+- The `dumptxoutset` RPC outputs a serialized snapshot of the current
+  UTXO set.  A script is provided in the `contrib/devtools` directory
+  for generating a snapshot of the UTXO set at a particular block
+  height.  (#16899)
+
+- The `generatetodescriptor` RPC allows testers using regtest mode to
+  generate blocks that pay an arbitrary output script descriptor.
+  (#16943)
+
+Updated RPCs
+------------
+
+- The `verifychain` RPC default values are now static instead of
+  depending on the command line options or configuration file
+  (`-checklevel`, and `-checkblocks`). Users can pass in the RPC
+  arguments explicitly when they don't want to rely on the default
+  values. (#18541)
+
+- The `getblockchaininfo` RPC's `verificationprogress` field will no
+  longer report values higher than 1.  Previously it would occasionally
+  report the chain was more than 100% verified.  (#17328)
+
+Tests
+-----
+
+- It is now an error to use an unqualified `walletdir=path` setting in
+  the config file if running on testnet or regtest networks. The setting
+  now needs to be qualified as `chain.walletdir=path` or placed in the
+  appropriate `[chain]` section. (#17447)
+
+- `-fallbackfee` was 0 (disabled) by default for the main chain, but
+  0.0002 by default for the test chains. Now it is 0 by default for all
+  chains. Testnet and regtest users will have to add
+  `fallbackfee=0.0002` to their configuration if they weren't setting it
+  and they want it to keep working like before. (#16524)
+
+Build system
+------------
+
+- Support is provided for building with the Android Native Development
+  Kit (NDK).  (#16110)
