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 tested on operating systems using the Linux Kernel 3.17+, macOS 13+, and Windows 10+. 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 ===============

Mempool Policy

single standard transaction is now limited to 2500. Signature operations in all previous output scripts, in all input scripts, as well as all P2SH redeem scripts (if there are any) are counted toward the limit. The new limit is assumed to not affect any known typically formed standard transactions. The change was done to prepare for a possible BIP54 deployment in the future.

configuration option.

changed to 100 satoshis per kvB. They can still be changed using their respective configuration options, but it is recommended to change both together if you decide to do so. - Other minimum feerates (e.g. the dust feerate, the minimum returned by the fee estimator, and all feerates used by the wallet) remain unchanged. The mempool minimum feerate still changes in response to high volume. - Note that unless these lower defaults are widely adopted across the network, transactions created with lower fee rates are not guaranteed to propagate or confirm. The wallet feerates remain unchanged; -mintxfee must be changed before attempting to create transactions with lower feerates using the wallet.

Logging

Unconditional logging to disk is now rate limited by giving each source location a quota of 1MiB per hour. Unconditional logging is any logging with a log level higher than debug, that is info, warning, and error. All logs will be prefixed with [*] if there is at least one source location that is currently being suppressed. (#32604)

When -logsourcelocations is enabled, the log output now contains the entire function signature instead of just the function name. (#32604)

RPC

v29.0 behavior, use the latest parameter. Documenting this change was missed in the v29.0 release notes. (#30808)
