Raw Blame History

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 10.14+, 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)

Updated RPCs

New RPCs

Build System

Files

  • On startup, the list of banned hosts and networks (via setban RPC) in banlist.dat is ignored and only banlist.json is considered. Bitcoin Core version 22.x is the only version that can read banlist.dat and also write it to banlist.json. If banlist.json already exists, version 22.x will not try to translate the banlist.dat into json. After an upgrade, listbanned can be used to double check the parsed entries. (#22570)

New settings

Updated settings

Tools and Utilities

  • Update -getinfo to return data in a user-friendly format that also reduces vertical space. (#21832)

Wallet

GUI changes

Low-level changes

RPC

  • getblockchaininfo now returns a new time field, that provides the chain tip time. (#22407)

Tests

  • For the regtest network the BIP 66 (DERSIG) activation height was changed from 1251 to 102. (#22632)
