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!
