 Change Log
 ==========
 
+Release 2.22.0 (21 Dec 2025)
+----------------------------
+
+* Added a new config option `utf8_decode_errors` for handling UTF-8
+  decode errors when parsing certain fields in SSH packets (disconnect
+  error, debug message, userauth banner, channel open failure reason,
+  channel exit signal reason, and SFTP error reason). The default
+  continues to behave as before, raising a ProtocolError exception,
+  but this option allows invalid bytes to be removed or replaced.
+  Thanks go to GitHub user Le-Syl21 for suggesting this.
+
+* Changed config parser to Ignore subdirectories and parse only plain
+  files matching a glob pattern in include directives, better matching
+  the behavior of other SSH implementations. Thanks go to Jacopo Nespolo
+  for contributing this change.
+
+* Improved a previous fix for a race condition which sometimes triggered
+  assertion errors in SSHForwarder. Thanks go to Mike Barry for reporting
+  the issue and helping to test the improved fix.
+
+* Removed optional dependency on libnacl/libsodium for chacha20 and
+  Edwrds curves, now that these are available in all supported
+  versions of the cryptography package.
+
+* Updated asyncssh to use version 2 of the fido2 package, and update
+  minimum Python version to 3.10, required by that updated package.
+
+* Fixed issue with the OpenSSL legacy provider on Windows and
+  re-enabled OpenSSL use in unit tests on Windows.
+
+* Inproved "run multiple clients" example to show the hostname being
+  accessed by each task.
+
+* Added unit testing for Python 3.14 and dropped 3.8 and 3.9.
