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.
