<\/figure>\n\n\n\nv29.4.knots20260508<\/a><\/p>\n\n\n\n Bitcoin Knots version 29.4.knots20260508 is now available from:<\/p>\n\n\n\n https:\/\/bitcoinknots.org\/files\/29.x\/29.4.knots20260508<\/a><\/p>\n\n\n\n This release includes various bug fixes, performance improvements, and extra safeguards. There are no critical fixes, so updating is not urgent.<\/p>\n\n\n\n Please report bugs using the issue tracker at GitHub:<\/p>\n\n\n\n https:\/\/github.com\/bitcoinknots\/bitcoin\/issues<\/a><\/p>\n\n\n\n To receive security and update notifications, please subscribe to:<\/p>\n\n\n\n https:\/\/bitcoinknots.org\/list\/announcements\/join<\/a><\/p>\n\n\n\n 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 Upgrading directly from very old versions of Bitcoin Core or Knots is possible, but it might take some time if the data directory needs to be migrated. Old wallet versions of Bitcoin Knots are generally supported.<\/p>\n\n\n\n Bitcoin Knots is supported on operating systems using the Linux kernel, macOS 13+, and Windows 10+. It is not recommended to use Bitcoin Knots on unsupported systems.<\/p>\n\n\n\n In various locations, including the GUI’s transaction details dialog and the Due to disruption of the shared Bitcoin Transifex repository, this release still does not include updated translations, and Bitcoin Knots may be unable to do so until\/unless that is resolved.<\/p>\n\n\n\n This release fixes an issue where the chainstate database would repeatedly rewrite large portions of itself, causing excessive disk reads and writes during normal operation.<\/p>\n\n\n\n It also checks for corruption that may be caused by running old node software after BIP110 has entered mandatory signaling. Running old node software, including the latest version of Bitcoin Core (since it has still not yet been updated), will no longer be a fully validating node or safe beginning approximately 2026 August 7th. That can cause the chain-state to become corrupted in some scenarios. This version of Knots will detect and recover from this kind of corruption.<\/p>\n\n\n\nluke-jr<\/a> released this 16 hours ago<\/p>\n\n\n\n
