I would like to announce the release of MediaWiki 1.42.5!

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

It is to fix a vendor issue, as reported in T382783. The version of Parsoid included in the vendor folder did not match the version in the composer.json file in MediaWiki core.

Other maintenance bug fixes have also been backported, and will be included in point releases for other MediaWiki branches (1.39 and 1.43) in the next security and maintenance release due at the end of March 2025.

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.

It is strongly recommended to upgrade to either 1.42, which will be supported until June 2025, or to 1.43 (the next LTS after 1.39), which will be supported until December 2027.
