Tomorrow we will be issuing a security and maintenance release to all supported branches of MediaWiki.
The new releases will be:
This will resolve 5 issues in MediaWiki core (1 of which isn't applicable to MediaWiki 1.31 at all), and also includes some fixes previously committed to git, including minor security and hardening patches along with bug fixes included for maintenance reasons.
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 , November 2020 was the scheduled EOL date for the REL1_34. MediaWiki 1.35.1 will be supported until at least September 2023, and would be the recommended upgrade path for anyone still using 1.34.
