Hey all,
This is a quick note to highlight that in three weeks' time, the REL1_45
branch will be created for MediaWiki core and each of the extensions and
skins in Wikimedia git, with some (the 'tarball') included as sub-modules
of MediaWiki itself[0]. This is the first step in the release process for
MediaWiki 1.45, which should be out in November 2025, approximately six
months
after MediaWiki 1.44.
The branches will reflect the code as of the last 'alpha' branch for the
release, 1.45.0-wmf.25, which will be deployed to Wikimedia wikis in the
week beginning 28 October 2025 for MediaWiki itself and those extensions
and skins available there.
After that point, patches that land in the main development branch of
MediaWiki and its bundled extensions and skins will be instead be slated
for the MediaWiki 1.45 release unless specifically backported[1].
If you are working on a new feature that you wish to land for the release,
you now have a few days to finish your work and land it in the development
branch; feature changes should not be backported except in an urgent case.
If your work might not be complete in time, and yet should block release
for everyone else, please file a task against the `mw-1.45-release` project
on Phabricator.[2]
If you have tickets that are already tagged for `mw-1.45-release`, please
finish them, untag them, or reach out to get them resolved in the next few
weeks.
We hope to issue the first release candidate, 1.45.0-rc.0, two weeks after
the branch point, and if all goes well, to release MediaWiki 1.45.0 a few
weeks after that.

Hi all,
On Thursday we will be issuing a security and maintenance release to all
supported branches of MediaWiki.
The new releases will be:
- 1.39.14
- 1.43.4
- 1.44.1
This will also resolve security issues in bundled extensions, along with
bug fixes included for maintenance reasons.
These security issues also affect many unsupported versions of MediaWiki.
We will make the fixes available in the respective release branches and
master in git. 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 later.
As a reminder, MediaWiki 1.35 became end of life (EOL) in December 2023,
MediaWiki 1.40 became EOL in June 2024, MediaWiki 1.41 became EOL in
December 2024 and MediaWiki 1.42 became EOL at the end of June 2025.
MediaWiki 1.39 (the old LTS before 1.43) becomes EOL in December 2025. It
is strongly recommended to upgrade to 1.43 (the next LTS after 1.39), which
will be supported until December 2027.
More information on these timelines can be viewed on the Version lifecycle
page at [1].
