\ No newline at end of file +25.0 Release Notes +================== + +Bitcoin Core version 25.0 is now available from: + + <https://bitcoincore.org/bin/bitcoin-core-25.0/> + +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 macOS) +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 10.15+, 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. + +Notable changes +=============== + +P2P and network changes +----------------------- + +- Transactions of non-witness size 65 and above are now allowed by mempool + and relay policy. This is to better reflect the actual afforded protections + against CVE-2017-12842 and open up additional use-cases of smaller transaction sizes. (#26265) + +New RPCs +-------- + +- The scanblocks RPC returns the relevant blockhashes from a set of descriptors by + scanning all blockfilters in the given range. It can be used in combination with + the getblockheader and rescanblockchain RPCs to achieve fast wallet rescans. Note + that this functionality can only be used if a compact block filter index + (-blockfilterindex=1) has been constructed by the node. (#23549) + +Updated RPCs +------------ + +- All JSON-RPC methods accept a new [named + parameter](JSON-RPC-interface.md#parameter-passing) called `args` that can + contain positional parameter values. This is a convenience to allow some + parameter values to be passed by name without having to name every value. The + python test framework and `bitcoin-cli` tool both take advantage of this, so + for example: + +```sh +bitcoin-cli -named createwallet wallet_name=mywallet load_on_startup=1 +``` + +Can now be shortened to: + +```sh +bitcoin-cli -named createwallet mywallet load_on_startup=1 +``` + +- The `verifychain` RPC will now return `false` if the checks didn't fail, + but couldn't be completed at the desired depth and level. This could be due + to missing data while pruning, due to an insufficient dbcache or due to + the node being shutdown before the call could finish. (#25574) + +- `sendrawtransaction` has a new, optional argument, `maxburnamount` with a default value of `0`. + Any transaction containing an unspendable output with a value greater than `maxburnamount` will + not be submitted. At present, the outputs deemed unspendable are those with scripts that begin + with an `OP_RETURN` code (known as 'datacarriers'), scripts that exceed the maximum script size, + and scripts that contain invalid opcodes. + +- The `testmempoolaccept` RPC now returns 2 additional results within the "fees" result: + "effective-feerate" is the feerate including fees and sizes of transactions validated together if + package validation was used, and also includes any modified fees from prioritisetransaction. The + "effective-includes" result lists the wtxids of transactions whose modified fees and sizes were used + in the effective-feerate (#26646). + +- `decodescript` may now infer a Miniscript descriptor under P2WSH context if it is not lacking + information. (#27037) + +- `finalizepsbt` is now able to finalize a transaction with inputs spending Miniscript-compatible + P2WSH scripts. (#24149) + +Changes to wallet related RPCs can be found in the Wallet section below. + +Build System +------------ + +- The `--enable-upnp-default` and `--enable-natpmp-default` options + have been removed. If you want to use port mapping, you can + configure it using a .conf file, or by passing the relevant + options at runtime. (#26896) + +Updated settings +---------------- + +- If the `-checkblocks` or `-checklevel` options are explicitly provided by the +user, but the verification checks cannot be completed due to an insufficient +dbcache, Bitcoin Core will now return an error at startup. (#25574) + +- Ports specified in `-port` and `-rpcport` options are now validated at startup. + Values that previously worked and were considered valid can now result in errors. (#22087) + +- Setting `-blocksonly` will now reduce the maximum mempool memory + to 5MB (users may still use `-maxmempool` to override). Previously, + the default 300MB would be used, leading to unexpected memory usage + for users running with `-blocksonly` expecting it to eliminate + mempool memory usage. + + As unused mempool memory is shared with dbcache, this also reduces + the dbcache size for users running with `-blocksonly`, potentially + impacting performance. +- Setting `-maxconnections=0` will now disable `-dnsseed` + and `-listen` (users may still set them to override). + +Changes to GUI or wallet related settings can be found in the GUI or Wallet section below. + +New settings +------------ + +- The `shutdownnotify` option is used to specify a command to execute synchronously +before Bitcoin Core has begun its shutdown sequence. (#23395) + + +Wallet +------ + +- The `minconf` option, which allows a user to specify the minimum number +of confirmations a UTXO being spent has, and the `maxconf` option, +which allows specifying the maximum number of confirmations, have been +added to the following RPCs in #25375: + - `fundrawtransaction` + - `send` + - `walletcreatefundedpsbt` + - `sendall` + +- Added a new `next_index` field in the response in `listdescriptors` to + have the same format as `importdescriptors` (#26194) + +- RPC `listunspent` now has a new argument `include_immature_coinbase` + to include coinbase UTXOs that don't meet the minimum spendability + depth requirement (which before were silently skipped). (#25730) + +- Rescans for descriptor wallets are now significantly faster if compact + block filters (BIP158) are available. Since those are not constructed + by default, the configuration option "-blockfilterindex=1" has to be + provided to take advantage of the optimization. This improves the + performance of the RPC calls `rescanblockchain`, `importdescriptors` + and `restorewallet`. (#25957) + +- RPC `unloadwallet` now fails if a rescan is in progress. (#26618) + +- Wallet passphrases may now contain null characters. + Prior to this change, only characters up to the first + null character were recognized and accepted. (#27068) + +- Address Purposes strings are now restricted to the currently known values of "send", + "receive", and "refund". Wallets that have unrecognized purpose strings will have + loading warnings, and the `listlabels` RPC will raise an error if an unrecognized purpose + is requested. (#27217) + +- In the `createwallet`, `loadwallet`, `unloadwallet`, and `restorewallet` RPCs, the + "warning" string field is deprecated in favor of a "warnings" field that + returns a JSON array of strings to better handle multiple warning messages and + for consistency with other wallet RPCs. The "warning" field will be fully + removed from these RPCs in v26. It can be temporarily re-enabled during the + deprecation period by launching bitcoind with the configuration option + `-deprecatedrpc=walletwarningfield`. (#27279) + +- Descriptor wallets can now spend coins sent to P2WSH Miniscript descriptors. (#24149) + +GUI changes +----------- + +- The "Mask values" is a persistent option now. (gui#701) +- The "Mask values" option affects the "Transaction" view now, in addition to the + "Overview" one. (gui#708) + +REST +---- + +- A new `/rest/deploymentinfo` endpoint has been added for fetching various + state info regarding deployments of consensus changes. (#25412) + +Binary verification +---- + +- The binary verification script has been updated. In previous releases it + would verify that the binaries had been signed with a single "release key". + In this release and moving forward it will verify that the binaries are + signed by a _threshold of trusted keys_. For more details and + examples, see: + https://github.com/bitcoin/bitcoin/blob/master/contrib/verify-binaries/README.md + (#27358) + +Low-level changes +================= + +RPC +--- + +- The JSON-RPC server now rejects requests where a parameter is specified multiple + times with the same name, instead of silently overwriting earlier parameter values + with later ones. (#26628) +- RPC `listsinceblock` now accepts an optional `label` argument + to fetch incoming transactions having the specified label. (#25934) +- Previously `setban`, `addpeeraddress`, `walletcreatefundedpsbt`, methods + allowed non-boolean and non-null values to be passed as boolean parameters. + Any string, number, array, or object value that was passed would be treated + as false. After this change, passing any value except `true`, `false`, or + `null` now triggers a JSON value is not of expected type error.
