I would like to announce the release of MediaWiki 1.31.11 and 1.35.1!

These releases also serve as a maintenance release for these branches. Numerous fixes have been backported into 1.35, including some for PHP 8.0 support (though we are not declaring full PHP 8.0 support yet).

T268894 doesn't apply to MediaWiki 1.31, as the code was added in 1.35. Also, only one of the two fixes of T268938 apply to MediaWiki 1.31, as the code was not added until MediaWiki 1.33.

While tarballs have already been uploaded, git tags will follow later on today.

An "MediaWiki Extensions Security Release Supplement" email will follow this one.
