Hi all,

I would like to announce the release of MediaWiki 1.32.2, 1.31.2, 1.30.2 and 1.27.6!

These releases fix 11 security issues in core (not 12 as reported in the pre-release announcement. This was a mistake, sorry!) and also includes some previously committed to git as minor security and hardening patches. Download links are given at the end of this email.

Patches will be pushed to Gerrit after this email is sent, and will land into the relevant branches as fast as our CI infrastructure allows. Git tags will follow soon after. All related tasks will be made public in Phabricator too in the following few hours.

Please note that December 2018 was the End-Of-Life date for MediaWiki 1.30. This means that MediaWiki 1.30.2 will be the last security release for that version, barring any unforeseen issues. We would strongly encourage users of MediaWiki 1.30 to upgrade to MediaWiki 1.31 (LTS version), released in June 2018, or a yet newer version as soon as possible. MediaWiki 1.31 will be supported until July 2021. See https://www.mediawiki.org/wiki/Version_lifecycle for more information.

June 2019 is the scheduled End-Of-Life date for MediaWiki 1.27 (the old LTS version). This means that MediaWiki 1.27.6 will be the last security release for that version, barring any unforeseen issues. We would strongly encourage users of MediaWiki 1.27 to upgrade to MediaWiki 1.31 (LTS version), released in June 2018, or a yet newer version as soon as possible. MediaWiki 1.31 will be supported until July 2021. See https://www.mediawiki.org/wiki/Version_lifecycle for more information.

This release also serves as a maintenance release for these branches.
