After branching off for a major version release of Bitcoin Core, use this template to create the initial release notes draft.
The release notes draft is a temporary file that can be added to by anyone. See /doc/developer-notes.md#release-notes for the process.
Create the draft, named "version Release Notes Draft" (e.g. "22.0 Release Notes Draft"), as a collaborative wiki in:
https://github.com/bitcoin-core/bitcoin-devwiki/wiki/
Before the final release, move the notes back to this git repository.

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 10.15+, 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
- A bitcoind node will no longer rumour addresses to inbound peers by default. They will become eligible for address gossip after sending an ADDR, ADDRV2, or GETADDR message. (#21528)
Fee estimation changes
- Fee estimation now takes the feerate of replacement (RBF) transactions into account. (#22539)
Rescan startup parameter removed
The -rescan
startup parameter has been removed. Wallets which require
rescanning due to corruption will still be rescanned on startup.
Otherwise, please use the rescanblockchain
RPC to trigger a rescan. (#23123)
Updated RPCs
-
The
-deprecatedrpc=addresses
configuration option has been removed. RPCsgettxout
,getrawtransaction
,decoderawtransaction
,decodescript
,gettransaction verbose=true
and REST endpoints/rest/tx
,/rest/getutxos
,/rest/block
no longer return theaddresses
andreqSigs
fields, which were previously deprecated in 22.0. (#22650) -
The
getblock
RPC command now supports verbose level 3 containing transaction inputsprevout
information. The existing/rest/block/
REST endpoint is modified to contain this information too. Everyvin
field will contain an additionalprevout
subfield describing the spent output.prevout
contains the following keys:generated
- true if the spent coins was a coinbase.height
value
scriptPubKey
-
listunspent
now includesancestorcount
,ancestorsize
, andancestorfees
for each transaction output that is still in the mempool. (#12677) -
lockunspent
now optionally takes a third parameter,persistent
, which causes the lock to be written persistently to the wallet database. This allows UTXOs to remain locked even after node restarts or crashes. (#23065)
New RPCs
Build System
Files
- On startup, the list of banned hosts and networks (via
setban
RPC) inbanlist.dat
is ignored and onlybanlist.json
is considered. Bitcoin Core version 22.x is the only version that can readbanlist.dat
and also write it tobanlist.json
. Ifbanlist.json
already exists, version 22.x will not try to translate thebanlist.dat
into json. After an upgrade,listbanned
can be used to double check the parsed entries. (#22570)
New settings
Updated settings
-
In previous releases, the meaning of the command line option
-persistmempool
(without a value provided) incorrectly disabled mempool persistence.-persistmempool
is now treated like other boolean options to mean-persistmempool=1
. Passing-persistmempool=0
,-persistmempool=1
and-nopersistmempool
is unaffected. (#23061) -
-maxuploadtarget
now allows human readable byte units [k|K|m|M|g|G|t|T]. E.g.-maxuploadtarget=500g
. No whitespace, +- or fractions allowed. Default isM
if no suffix provided. (#23249)
Tools and Utilities
-
Update
-getinfo
to return data in a user-friendly format that also reduces vertical space. (#21832) -
CLI
-addrinfo
now returns a single field for the number ofonion
addresses known to the node instead of separatetorv2
andtorv3
fields, as support for Tor V2 addresses was removed from Bitcoin Core in 22.0. (#22544)
Wallet
GUI changes
- UTXOs which are locked via the GUI are now stored persistently in the wallet database, so are not lost on node shutdown or crash. (#23065)
Low-level changes
RPC
getblockchaininfo
now returns a newtime
field, that provides the chain tip time. (#22407)
Tests
- For the
regtest
network the activation heights of several softforks were set to block height 1. They can be changed by the runtime setting-testactivationheight=name@height
. (#22818)
