Hi all,

Tomorrow we will be issuing a security and maintenance release to all supported branches of MediaWiki.

The new releases will be:

- 1.34.3
- 1.31.9

This will resolve eight issues in MediaWiki core (two of which aren't applicable to MediaWiki 1.31), and also includes some fixes previously committed to git, including minor security and hardening patches along with bug fixes included for maintenance reasons.

For those of you waiting on MediaWiki 1.35.0, this will also come either tomorrow, or at latest Friday (depending on CI load), including the security fixes applied to these other supported release branches. We thank you for your patience; the current global situation means things have taken longer than would have been expected, but it has meant more bug fixes being incorporated from testing across the board. It also meant not having a security 1.35.1 release followup only a couple of weeks after 1.35.0 coming out. Which, for many people would mean extra work to upgrade again, and it was decided to avoid this.

We will make the fixes available in these respective release branches, and also master. Tarballs will be available for the above mentioned point releases as well.

A summary of some of the security fixes that have gone into non-bundled MediaWiki extensions will also follow.

As per the MediaWiki Version lifecycle [1], November 2020 is the scheduled EOL date for the REL1_34. 1.34.3 will therefore potentially be the final release of the MediaWiki 1.34 branch, barring any unforeseen issues. As per above, MediaWiki 1.35.0 will be released this week, and will be supported until at least September 2023, and would be the recommended upgrade path.
