+22.1 Release Notes
+==================
+
+Bitcoin Core version 22.1 is now available from:
+
+  <https://bitcoincore.org/bin/bitcoin-core-22.1/>
+
+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 10.14+, 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.
+
+From Bitcoin Core 22.0 onwards, macOS versions earlier than 10.14 are no longer supported.
+
+Notable changes
+===============
+
+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)
