Sorry all for the inconvenience.

There's a couple of issues relating to some of the backports in the User/ActorMigration changes. As such, I would advise against applying these patches unless you really know what you are doing.

Fixes are being worked on, and will hopefully be released in a few hours.

I would like to announce the release of MediaWiki 1.34.3, and 1.31.9!

These releases also serve as a maintenance release for these branches.

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

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

As mentioned in the pre-release announcement, this will potentially be the final release of the MediaWiki 1.34 branch, barring any unforeseen issues. For continued support in the future, you are advised to upgrade to MediaWiki 1.35 in the near future.

The release announcement for MediaWiki 1.35 will follow this one before the end of day tomorrow. MediaWiki 1.35 will be supported until September 2023.
