+0.21.0 Release Notes
+====================
+
+Bitcoin Core version 0.21.0 is now available from:
+
+ <https://bitcoincore.org/bin/bitcoin-core-0.21.0/>
+
+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.
+
+The node's known peers are persisted to disk in a file called `peers.dat`. The
+format of this file has been changed in a backwards-incompatible way in order to
+accommodate the storage of Tor v3 and other BIP155 addresses. This means that if
+the file is modified by 0.21.0 or newer then older versions will not be able to
+read it. Those old versions, in the event of a downgrade, will log an error
+message "Incorrect keysize in addrman deserialization" and will continue normal
+operation as if the file was missing, creating a new empty one. (#19954, #20284)
+
+Notable changes
+===============
+
+P2P and network changes
+-----------------------
+
+- The mempool now tracks whether transactions submitted via the wallet or RPCs
+ have been successfully broadcast. Every 10-15 minutes, the node will try to
+ announce unbroadcast transactions until a peer requests it via a `getdata`
+ message or the transaction is removed from the mempool for other reasons.
+ The node will not track the broadcast status of transactions submitted to the
+ node using P2P relay. This version reduces the initial broadcast guarantees
+ for wallet transactions submitted via P2P to a node running the wallet. (#18038)
+
+- The size of the set of transactions that peers have announced and we consider
+ for requests has been reduced from 100000 to 5000 (per peer), and further
+ announcements will be ignored when that limit is reached. If you need to dump
+ (very) large batches of transactions, exceptions can be made for trusted
+ peers using the "relay" network permission. For localhost for example it can
+ be enabled using the command line option `-whitelist=relay@127.0.0.1`.
+ (#19988)
+
+- This release adds support for Tor version 3 hidden services, and rumoring them
+ over the network to other peers using
+ [BIP155](https://github.com/bitcoin/bips/blob/master/bip-0155.mediawiki).
+ Version 2 hidden services are still fully supported by Bitcoin Core, but the
+ Tor network will start
+ [deprecating](https://blog.torproject.org/v2-deprecation-timeline) them in the
+ coming months. (#19954)
+
+- The Tor onion service that is automatically created by setting the
+ `-listenonion` configuration parameter will now be created as a Tor v3 service
+ instead of Tor v2. The private key that was used for Tor v2 (if any) will be
+ left untouched in the `onion_private_key` file in the data directory (see
+ `-datadir`) and can be removed if not needed. Bitcoin Core will no longer
+ attempt to read it. The private key for the Tor v3 service will be saved in a
+ file named `onion_v3_private_key`. To use the deprecated Tor v2 service (not
+ recommended), the `onion_private_key` can be copied over
+ `onion_v3_private_key`, e.g.
+ `cp -f onion_private_key onion_v3_private_key`. (#19954)
+
+- The client writes a file (`anchors.dat`) at shutdown with the network addresses
+ of the node’s two outbound block-relay-only peers (so called "anchors"). The
+ next time the node starts, it reads this file and attempts to reconnect to those
+ same two peers. This prevents an attacker from using node restarts to trigger a
+ complete change in peers, which would be something they could use as part of an
+ eclipse attack. (#17428)
+
+- This release adds support for serving
+ [BIP157](https://github.com/bitcoin/bips/blob/master/bip-0157.mediawiki) compact
+ filters to peers on the network when enabled using
+ `-blockfilterindex=1 -peercfilters=1`. (#16442)
+
+- This release adds support for signets
+ ([BIP325](https://github.com/bitcoin/bips/blob/master/bip-0325.mediawiki)) in
+ addition to the existing mainnet, testnet, and regtest networks. Signets are
+ centrally-controlled test networks, allowing them to be more predictable
+ test environments than the older testnet. One public signet is maintained, and
+ selectable using `-signet`. It is also possible to create personal signets.
+ (#18267).
+
+- This release implements
+ [BIP339](https://github.com/bitcoin/bips/blob/master/bip-0339.mediawiki)
+ wtxid relay. When negotiated, transactions are announced using their wtxid
+ instead of their txid. (#18044).
+
+- This release implements the proposed Taproot consensus rules
+ ([BIP341](https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki) and
+ [BIP342](https://github.com/bitcoin/bips/blob/master/bip-0342.mediawiki)),
+ without activation on mainnet. Experimentation with Taproot can be done on
+ signet, where its rules are already active. (#19553)
+
+Updated RPCs
+------------
+
+- The `getpeerinfo` RPC has a new `network` field that provides the type of
+ network ("ipv4", "ipv6", or "onion") that the peer connected through. (#20002)
+
+- The `getpeerinfo` RPC now has additional `last_block` and `last_transaction`
+ fields that return the UNIX epoch time of the last block and the last *valid*
+ transaction received from each peer. (#19731)
+
+- `getnetworkinfo` now returns two new fields, `connections_in` and
+ `connections_out`, that provide the number of inbound and outbound peer
+ connections. These new fields are in addition to the existing `connections`
+ field, which returns the total number of peer connections. (#19405)
+
+- Exposed transaction version numbers are now treated as unsigned 32-bit
+ integers instead of signed 32-bit integers. This matches their treatment in
+ consensus logic. Versions greater than 2 continue to be non-standard
+ (matching previous behavior of smaller than 1 or greater than 2 being
+ non-standard). Note that this includes the `joinpsbt` command, which combines
+ partially-signed transactions by selecting the highest version number.
+ (#16525)
+
+- `getmempoolinfo` now returns an additional `unbroadcastcount` field. The
+ mempool tracks locally submitted transactions until their initial broadcast
+ is acknowledged by a peer. This field returns the count of transactions
+ waiting for acknowledgement.
+
+- Mempool RPCs such as `getmempoolentry` and `getrawmempool` with
+ `verbose=true` now return an additional `unbroadcast` field. This indicates
+ whether initial broadcast of the transaction has been acknowledged by a
+ peer. `getmempoolancestors` and `getmempooldescendants` are also updated.
+
+- The `getpeerinfo` RPC no longer returns the `banscore` field unless the configuration
+ option `-deprecatedrpc=banscore` is used. The `banscore` field will be fully
+ removed in the next major release. (#19469)
+
+- The `testmempoolaccept` RPC returns `vsize` and a `fees` object with the `base` fee
+ if the transaction would pass validation. (#19940)
+
+- The `getpeerinfo` RPC now returns a `connection_type` field. This indicates
+ the type of connection established with the peer. It will return one of six
+ options. For more information, see the `getpeerinfo` help documentation.
+ (#19725)
+
+- The `getpeerinfo` RPC no longer returns the `addnode` field by default. This
+ field will be fully removed in the next major release. It can be accessed
+ with the configuration option `-deprecatedrpc=getpeerinfo_addnode`. However,
+ it is recommended to instead use the `connection_type` field (it will return
+ `manual` when addnode is true). (#19725)
+
+- The `getpeerinfo` RPC no longer returns the `whitelisted` field by default.
+ This field will be fully removed in the next major release. It can be accessed
+ with the configuration option `-deprecatedrpc=getpeerinfo_whitelisted`. However,
+ it is recommended to instead use the `permissions` field to understand if specific
+ privileges have been granted to the peer. (#19770)
+
+- The `walletcreatefundedpsbt` RPC call will now fail with
+ `Insufficient funds` when inputs are manually selected but are not enough to cover
+ the outputs and fee. Additional inputs can automatically be added through the
+ new `add_inputs` option. (#16377)
+
+- The `fundrawtransaction` RPC now supports `add_inputs` option that when `false`
+ prevents adding more inputs if necessary and consequently the RPC fails.
+
+Changes to Wallet or GUI related RPCs can be found in the GUI or Wallet section below.
+
+New RPCs
+--------
+
+- The `getindexinfo` RPC returns the actively running indices of the node,
+ including their current sync status and height. It also accepts an `index_name`
+ to specify returning the status of that index only. (#19550)
+
+Build System
+------------
+
+Updated settings
+----------------
+
+- The same ZeroMQ notification (e.g. `-zmqpubhashtx=address`) can now be
+ specified multiple times to publish the same notification to different ZeroMQ
+ sockets. (#18309)
+
+- The `-banscore` configuration option, which modified the default threshold for
+ disconnecting and discouraging misbehaving peers, has been removed as part of
+ changes in 0.20.1 and in this release to the handling of misbehaving peers.
+ Refer to "Changes regarding misbehaving peers" in the 0.20.1 release notes for
+ details. (#19464)
+
+- The `-debug=db` logging category, which was deprecated in 0.20 and replaced by
+ `-debug=walletdb` to distinguish it from `coindb`, has been removed. (#19202)
+
+- A `download` permission has been extracted from the `noban` permission. For
+ compatibility, `noban` implies the `download` permission, but this may change
+ in future releases. Refer to the help of the affected settings `-whitebind`
+ and `-whitelist` for more details. (#19191)
+
+- Netmasks that contain 1-bits after 0-bits (the 1-bits are not contiguous on
+ the left side, e.g. 255.0.255.255) are no longer accepted. They are invalid
+ according to RFC 4632. Netmasks are used in the `-rpcallowip` and `-whitelist`
+ configuration options and in the `setban` RPC. (#19628)
+
+- The `-blocksonly` setting now completely disables fee estimation. (#18766)
+
+Changes to Wallet or GUI related settings can be found in the GUI or Wallet section below.
+
+Tools and Utilities
+-------------------
+
+- A new `bitcoin-cli -netinfo` command provides a network peer connections
+ dashboard that displays data from the `getpeerinfo` and `getnetworkinfo` RPCs
+ in a human-readable format. An optional integer argument from `0` to `4` may
+ be passed to see increasing levels of detail. (#19643)
+
+- A new `bitcoin-cli -generate` command, equivalent to RPC `generatenewaddress`
+ followed by `generatetoaddress`, can generate blocks for command line testing
+ purposes. This is a client-side version of the former `generate` RPC. See the
+ help for details. (#19133)
+
+- The `bitcoin-cli -getinfo` command now displays the wallet name and balance for
+ each of the loaded wallets when more than one is loaded (e.g. in multiwallet
+ mode) and a wallet is not specified with `-rpcwallet`. (#18594)
+
+- The `connections` field of `bitcoin-cli -getinfo` is now expanded to return a JSON
+ object with `in`, `out` and `total` numbers of peer connections. It previously
+ returned a single integer value for the total number of peer connections. (#19405)
+
+New settings
+------------
+
+- The `startupnotify` option is used to specify a command to
+ execute when Bitcoin Core has finished with its startup
+ sequence. (#15367)
+
+Wallet
+------
+
+- Backwards compatibility has been dropped for two `getaddressinfo` RPC
+ deprecations, as notified in the 0.20 release notes. The deprecated `label`
+ field has been removed as well as the deprecated `labels` behavior of
+ returning a JSON object containing `name` and `purpose` key-value pairs. Since
+ 0.20, the `labels` field returns a JSON array of label names. (#19200)
+
+- To improve wallet privacy, the frequency of wallet rebroadcast attempts is
+ reduced from approximately once every 15 minutes to once every 12-36 hours.
+ To maintain a similar level of guarantee for initial broadcast of wallet
+ transactions, the mempool tracks these transactions as a part of the newly
+ introduced unbroadcast set. See the "P2P and network changes" section for
+ more information on the unbroadcast set. (#18038)
+
+- The `sendtoaddress` and `sendmany` RPCs accept an optional `verbose=True`
+ argument to also return the fee reason about the sent tx. (#19501)
+
+- The wallet can create a transaction without change even when the keypool is
+ empty. Previously it failed. (#17219)
+
+- The `-salvagewallet` startup option has been removed. A new `salvage` command
+ has been added to the `bitcoin-wallet` tool which performs the salvage
+ operations that `-salvagewallet` did. (#18918)
+
+- A new configuration flag `-maxapsfee` has been added, which sets the max
+ allowed avoid partial spends (APS) fee. It defaults to 0 (i.e. fee is the
+ same with and without APS). Setting it to -1 will disable APS, unless
+ `-avoidpartialspends` is set. (#14582)
+
+- The wallet will now avoid partial spends (APS) by default, if this does not
+ result in a difference in fees compared to the non-APS variant. The allowed
+ fee threshold can be adjusted using the new `-maxapsfee` configuration
+ option. (#14582)
+
+- The `createwallet`, `loadwallet`, and `unloadwallet` RPCs now accept
+ `load_on_startup` options to modify the settings list. Unless these options
+ are explicitly set to true or false, the list is not modified, so the RPC
+ methods remain backwards compatible. (#15937)
+
+- A new `send` RPC with similar syntax to `walletcreatefundedpsbt`, including
+ support for coin selection and a custom fee rate, is added. The `send` RPC is
+ experimental and may change in subsequent releases. (#16378)
+
+- The `estimate_mode` parameter is now case-insensitive in the `bumpfee`,
+ `fundrawtransaction`, `sendmany`, `sendtoaddress`, `send` and
+ `walletcreatefundedpsbt` RPCs. (#11413)
+
+- The `bumpfee` RPC now uses `conf_target` rather than `confTarget` in the
+ options. (#11413)
+
+- `fundrawtransaction` and `walletcreatefundedpsbt` when used with the
+ `lockUnspents` argument now lock manually selected coins, in addition to
+ automatically selected coins. Note that locked coins are never used in
+ automatic coin selection, but can still be manually selected. (#18244)
+
+- The `-zapwallettxes` startup option has been removed and its functionality
+ removed from the wallet. This option was originally intended to allow for
+ rescuing wallets which were affected by a malleability attack. More recently,
+ it has been used in the fee bumping of transactions that did not signal RBF.
+ This functionality has been superseded with the abandon transaction feature. (#19671)
+
+- The error code when no wallet is loaded, but a wallet RPC is called, has been
+ changed from `-32601` (method not found) to `-18` (wallet not found).
+ (#20101)
+
+### Automatic wallet creation removed
+
+Bitcoin Core will no longer automatically create new wallets on startup. It will
+load existing wallets specified by `-wallet` options on the command line or in
+`bitcoin.conf` or `settings.json` files. And by default it will also load a
+top-level unnamed ("") wallet. However, if specified wallets don't exist,
+Bitcoin Core will now just log warnings instead of creating new wallets with
+new keys and addresses like previous releases did.
+
+New wallets can be created through the GUI (which has a more prominent create
+wallet option), through the `bitcoin-cli createwallet` or `bitcoin-wallet
+create` commands, or the `createwallet` RPC. (#15454, #20186)
+
+### Experimental Descriptor Wallets
+
+Please note that Descriptor Wallets are still experimental and not all expected functionality
+is available. Additionally there may be some bugs and current functions may change in the future.
+Bugs and missing functionality can be reported to the [issue tracker](https://github.com/bitcoin/bitcoin/issues).
+
+0.21 introduces a new type of wallet - Descriptor Wallets. Descriptor Wallets store
+scriptPubKey information using output descriptors. This is in contrast to the Legacy Wallet
+structure where keys are used to implicitly generate scriptPubKeys and addresses. Because of this
+shift to being script based instead of key based, many of the confusing things that Legacy
+Wallets do are not possible with Descriptor Wallets. Descriptor Wallets use a definition
+of "mine" for scripts which is simpler and more intuitive than that used by Legacy Wallets.
+Descriptor Wallets also uses different semantics for watch-only things and imports.
+
+As Descriptor Wallets are a new type of wallet, their introduction does not affect existing wallets.
+Users who already have a Bitcoin Core wallet can continue to use it as they did before without
+any change in behavior. Newly created Legacy Wallets (which remains the default type of wallet) will
+behave as they did in previous versions of Bitcoin Core.
+
+The differences between Descriptor Wallets and Legacy Wallets are largely limited to non user facing
+things. They are intended to behave similarly except for the import/export and watchonly functionality
+as described below.
+
+#### Creating Descriptor Wallets
+
+Descriptor wallets are not the default type of wallet.
+
+In the GUI, a checkbox has been added to the Create Wallet Dialog to indicate that a
+Descriptor Wallet should be created. And a `descriptors` option has been added to `createwallet` RPC.
+Setting `descriptors` to `true` will create a Descriptor Wallet instead of a Legacy Wallet.
+
+Without those options being set, a Legacy Wallet will be created instead.
+
+#### `IsMine` Semantics
+
+`IsMine` refers to the function used to determine whether a script belongs to the wallet.
+This is used to determine whether an output belongs to the wallet. `IsMine` in Legacy Wallets
+returns true if the wallet would be able to sign an input that spends an output with that script.
+Since keys can be involved in a variety of different scripts, this definition for `IsMine` can
+lead to many unexpected scripts being considered part of the wallet.
+
+With Descriptor Wallets, descriptors explicitly specify the set of scripts that are owned by
+the wallet. Since descriptors are deterministic and easily enumerable, users will know exactly
+what scripts the wallet will consider to belong to it. Additionally the implementation of `IsMine`
+in Descriptor Wallets is far simpler than for Legacy Wallets. Notably, in Legacy Wallets, `IsMine`
+allowed for users to take one type of address (e.g. P2PKH), mutate it into another address type
+(e.g. P2WPKH), and the wallet would still detect outputs sending to the new address type
+even without that address being requested from the wallet. Descriptor Wallets do not
+allow for this and will only watch for the addresses that were explicitly requested from the wallet.
+
+These changes to `IsMine` will make it easier to reason about what scripts the wallet will
+actually be watching for in outputs. However for the vast majority of users, this change is
+largely transparent and will not have noticeable effect.
+
+#### Imports and Exports
+
+In Legacy Wallets, raw scripts and keys could be imported to the wallet. Those imported scripts
+and keys are treated separately from the keys generated by the wallet. This complicates the `IsMine`
+logic as it has to distinguish between spendable and watchonly.
+
+Descriptor Wallets handle importing scripts and keys differently. Only complete descriptors can be
+imported. These descriptors are then added to the wallet as if it were a descriptor generated by
+the wallet itself. This simplifies the `IsMine` logic so that it no longer has to distinguish
+between spendable and watchonly. As such, the watchonly model for Descriptor Wallets is also
+different and described in more detail in the next section.
+
+To import into a Descriptor Wallet, a new `importdescriptors` RPC has been added that uses a syntax
+similar to that of `importmulti`.
+
+As Legacy Wallets and Descriptor Wallets use different mechanisms for storing and importing scripts and keys
+the existing import RPCs have been disabled for descriptor wallets.
+New export RPCs for Descriptor Wallets have not yet been added.
+
+The following RPCs are disabled for Descriptor Wallets:
+
+* `importprivkey`
+* `importpubkey`
+* `importaddress`
+* `importwallet`
+* `dumpprivkey`
+* `dumpwallet`
+* `importmulti`
+* `addmultisigaddress`
+* `sethdseed`
+
+#### Watchonly Wallets
+
+A Legacy Wallet contains both private keys and scripts that were being watched.
+Those watched scripts would not contribute to your normal balance. In order to see the watchonly
+balance and to use watchonly things in transactions, an `include_watchonly` option was added
+to many RPCs that would allow users to do that. However it is easy to forget to include this option.
+
+Descriptor Wallets move to a per-wallet watchonly model. Instead an entire wallet is considered to be
+watchonly depending on whether it was created with private keys disabled. This eliminates the need
+to distinguish between things that are watchonly and things that are not within a wallet itself.
+
+This change does have a caveat. If a Descriptor Wallet with private keys *enabled* has
+a multiple key descriptor without all of the private keys (e.g. `multi(...)` with only one private key),
+then the wallet will fail to sign and broadcast transactions. Such wallets would need to use the PSBT
+workflow but the typical GUI Send, `sendtoaddress`, etc. workflows would still be available, just
+non-functional.
+
+This issue is worsened if the wallet contains both single key (e.g. `wpkh(...)`) descriptors and such
+multiple key descriptors as some transactions could be signed and broadcast and others not. This is
+due to some transactions containing only single key inputs, while others would contain both single
+key and multiple key inputs, depending on which are available and how the coin selection algorithm
+selects inputs. However this is not considered to be a supported use case; multisigs
+should be in their own wallets which do not already have descriptors. Although users cannot export
+descriptors with private keys for now as explained earlier.
+
+#### BIP 44/49/84 Support
+
+The change to using descriptors changes the default derivation paths used by Bitcoin Core
+to adhere to BIP 44/49/84. Descriptors with different derivation paths can be imported without
+issue.
+
+#### SQLite Database Backend
+
+Descriptor wallets use SQLite for the wallet file instead of the Berkeley DB used in legacy wallets.
+This will break compatibility with any existing tooling that operates on wallets, however compatibility
+was already being broken by the move to descriptors.
+
+### Wallet RPC changes
+
+- The `upgradewallet` RPC replaces the `-upgradewallet` command line option.
+ (#15761)
+
+- The `settxfee` RPC will fail if the fee was set higher than the `-maxtxfee`
+ command line setting. The wallet will already fail to create transactions
+ with fees higher than `-maxtxfee`. (#18467)
+
+- A new `fee_rate` parameter/option denominated in satoshis per vbyte (sat/vB)
+ is introduced to the `sendtoaddress`, `sendmany`, `fundrawtransaction` and
+ `walletcreatefundedpsbt` RPCs as well as to the experimental new `send`
+ RPC. The legacy `feeRate` option in `fundrawtransaction` and
+ `walletcreatefundedpsbt` still exists for setting a fee rate in BTC per 1,000
+ vbytes (BTC/kvB), but it is expected to be deprecated soon to avoid
+ confusion. For these RPCs, the fee rate error message is updated from BTC/kB
+ to sat/vB and the help documentation in BTC/kB is updated to BTC/kvB. The
+ `send` and `sendtoaddress` RPC examples are updated to aid users in creating
+ transactions with explicit fee rates. (#20305, #11413)
+
+- The `bumpfee` RPC `fee_rate` option is changed from BTC/kvB to sat/vB and the
+ help documentation is updated. Users are warned that this is a breaking API
+ change, but it should be relatively benign: the large (100,000 times)
+ difference between BTC/kvB and sat/vB units means that a transaction with a
+ fee rate mistakenly calculated in BTC/kvB rather than sat/vB should raise an
+ error due to the fee rate being set too low. In the worst case, the
+ transaction may send at 1 sat/vB, but as Replace-by-Fee (BIP125 RBF) is active
+ by default when an explicit fee rate is used, the transaction fee can be
+ bumped. (#20305)
+
+GUI changes
+-----------
+
+- Wallets created or loaded in the GUI will now be automatically loaded on
+ startup, so they don't need to be manually reloaded next time Bitcoin Core is
+ started. The list of wallets to load on startup is stored in
+ `\<datadir\>/settings.json` and augments any command line or `bitcoin.conf`
+ `-wallet=` settings that specify more wallets to load. Wallets that are
+ unloaded in the GUI get removed from the settings list so they won't load
+ again automatically next startup. (#19754)
+
+- The GUI Peers window no longer displays a "Ban Score" field. This is part of
+ changes in 0.20.1 and in this release to the handling of misbehaving
+ peers. Refer to "Changes regarding misbehaving peers" in the 0.20.1 release
+ notes for details. (#19512)
+
+Low-level changes
+=================
+
+RPC
+---
+
+- To make RPC `sendtoaddress` more consistent with `sendmany` the following error
+ `sendtoaddress` codes were changed from `-4` to `-6`:
+ - Insufficient funds
+ - Fee estimation failed
+ - Transaction has too long of a mempool chain
+
+- The `sendrawtransaction` error code for exceeding `maxfeerate` has been changed from
+ `-26` to `-25`. The error string has been changed from "absurdly-high-fee" to
+ "Fee exceeds maximum configured by user (e.g. -maxtxfee, maxfeerate)." The
+ `testmempoolaccept` RPC returns `max-fee-exceeded` rather than `absurdly-high-fee`
+ as the `reject-reason`. (#19339)
+
+- To make wallet and rawtransaction RPCs more consistent, the error message for
+ exceeding maximum feerate has been changed to "Fee exceeds maximum configured by user
+ (e.g. -maxtxfee, maxfeerate)." (#19339)
+
+Tests
+-----
+
+- The BIP 325 default signet can be enabled by the `-chain=signet` or `-signet`
+ setting. The settings `-signetchallenge` and `-signetseednode` allow
+ enabling a custom signet.
+
+- The `generateblock` RPC allows testers using regtest mode to
+ generate blocks that consist of a custom set of transactions. (#17693)
