(Sorry if you have received this email already. There was an issue with
Mailman yesterday, and while the email was sent to mediawiki-l and
wikitech-l successfully, it seemingly never made it to the
mediawiki-announce archives. Email slightly modified to suit being sent
As per the MediaWiki version lifecycle, I would like to announce the
formal end of life (EOL) of MediaWiki 1.31 as of today, Thursday September
30, 2021, coinciding with the final security and maintenance release for
the branch, 1.31.16.
This means that MediaWiki 1.31 will no longer receive maintenance or
security backports. It is therefore strongly discouraged that you continue
to use it.
It is recommended to upgrade to MediaWiki 1.35, the current Long Term
Support (LTS) version which is not due to become EOL until September 2023.
MediaWiki 1.35 bumps the required PHP version from 7.0 in 1.31 (which is
unsupported upstream), to PHP 7.3.19 or later.
Tomorrow we will be issuing a security and maintenance release to all
supported branches of MediaWiki.
The new releases will be:
This will resolve 3 issues in MediaWiki core and also includes some fixes
previously committed to git, including minor security and hardening patches
along with bug fixes included for maintenance reasons.
It also fixes 1 issue in a MediaWiki tarball bundled extension.
We will make the fixes available in these respective release branches,
master and the currently unreleased 1.37 branch. 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 a reminder, 1.31 (the old LTS) was due to become end of life (EOL) in
June 2021. 1.35 (the new LTS) is supported until September 2023. However,
to try and meet our LTS-LTS overlap commitments (1.35 was late due to
COVID), 1.31 got best-efforts extra support until the end of September 2021.
As the end of September 2021 is now upon us, this means 1.31.16 will be the
final security (and maintenance) release, and therefore it is considered
EOL as of tomorrow, September 30, 2021.
