I would like to announce the availability of MediaWiki 1.39.2.

This release primarily is to fix various issues around database upgrades that users have reported on both MySQL/MariaDB and PostgreSQL.

In the case of MySQL/MariaDB, there may have been the chance of data loss (as always, please backup before upgrading!), and page views may have resulted in an error like "The revision #0 of the page named "x" does not exist." This was seen only when upgrading in a bigger jump between versions (for example 1.31 to 1.39). More information can be seen in https://phabricator.wikimedia.org/T326071.

https://phabricator.wikimedia.org/T328169 has been filed to write a maintenance script to fix the issues caused by these upgrades. It is expected this will be included in a later point release.

Various patches aimed at support for PHP 8.0, 8.1, and 8.2 have been back-ported. This should fix some log spam, and MediaWiki should work fully on versions PHP 8.0 and 8.1.

Reports of bugs with PHP 8.0, 8.1, or 8.2 support are particularly welcome, and fixes will be back-ported when possible. Please see https://phabricator.wikimedia.org/tag/php_8.0_support/, https://phabricator.wikimedia.org/tag/php_8.1_support/ and https://phabricator.wikimedia.org/tag/php_8.2_support/ for the relevant work boards.

The tarballs have already been uploaded as of this email; the git tag has also already been pushed.
