[IT-SecNots] [MediaWiki-announce] Maintenance release: MediaWiki 1.43.3

[Sam Reed <reedy AT wikimedia.org>]

I would like to announce the release of MediaWiki 1.43.3!

Thia release primarily serves as a maintenance release for this branch.

It is to fix a vendor issue, as reported in T398269. As part of the cleanup
post the WMF migration to PHP 8.1, the symfony/polyfill-php packages were
incorrectly defined in Vendor.

The tarballs have already been uploaded as of this email, and the git tags
have been pushed.

Reports of bugs with PHP 8.0, 8.1, 8.2, 8.3 and 8.4 support are
particularly welcome, and fixes will be back-ported when possible. Please
see https://phabricator.wikimedia.org/tag/php_8.0_support/,
https://phabricator.wikimedia.org/tag/php_8.1_support/,
https://phabricator.wikimedia.org/tag/php_8.2_support/,
https://phabricator.wikimedia.org/tag/php_8.3_support/ and
https://phabricator.wikimedia.org/tag/php_8.4_support/ for the relevant
work boards.

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 becames EOL, yesterday, June 30, 2025.

MediaWiki 1.39 (old LTS) 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.
