As per the MediaWiki version lifecycle[1], I would like to announce the
formal end of life (EOL) of MediaWiki 1.42 as of Monday June 30, 2025.
1.42.7 is expected to be the last release for this branch.
This means that MediaWiki 1.42 will no longer receive maintenance or
security backports. It is therefore strongly discouraged that you continue
to use it.
It is recommended to upgrade either to the next LTS, 1.43, which will be
supported until December 2027, or to the soon to be released MediaWiki
1.44, which will be supported until at least June 2026.
Thanks!

Hi all,
On Monday we will be issuing a security and maintenance release to all
supported branches of MediaWiki.
The new releases will be:
- 1.39.13
- 1.42.7
- 1.43.2
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 and MediaWiki 1.41 became EOL in
December 2024.
MediaWiki 1.42 becomes EOL at the end of June 2025.
MediaWiki 1.39 (the old LTS before 1.43) becomes EOL in November 2025.
It is strongly recommended to upgrade to 1.43 (the next LTS after 1.39),
which will be supported until December 2027.
