Description

Previous work: T263805: Write and send release announcements for MediaWiki 1.31.11/1.35.1

I would like to announce the release of MediaWiki 1.31.13 and 1.35.2!

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).

This is the first MediaWiki release where zip files are included too. This is due to some issues with the tarballs for some users with certain extraction applications.

Composer 2.0 is also now supported on MediaWiki 1.35.2.

MediaWiki also has a new logo as of these releases.

T270453 does not apply to MediaWiki 1.31.13, as VisualEditor is not bundled. However the patch will be backported to the 1.31 branch if you use VisualEditor, and you should pick up the update from the usual places.

T279451 also does not apply to MediaWiki 1.31.13, as Parsoid is not bundled. If you use the node.js service, it is recommended to update this.

T276843 has been fixed in different ways on MediaWiki 1.31.13 and MediaWiki 1.35.2. On the former, we have just disabled the known vulnerable lexers. On 1.35.2, we have upgraded pygments from 2.5.2 to 2.7.4.

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

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