+
+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
+===============
+
+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.
