As per https://www.mediawiki.org/wiki/Version_lifecycle, MW 1.32 is due to go EOL in January 2020.
A formal announcement should be sent confirming and actioning this
As per the MediaWiki version life cycle , I would like to announce the formal end of life (EOL) of MediaWiki 1.32 as of tomorrow, Friday January 24, 2019.
This means MediaWiki 1.32 will no longer receive maintenance or security backports. It is therefore not recommended for usage.
It is recommended to upgrade to MediaWiki 1.33 (due to become EOL in June 2020) or more preferably MediaWiki 1.34 (due to become EOL in November 2020). The current LTS, MediaWiki 1.31 is older (and downgrade is not supported), though the next LTS (MediaWiki 1.35) is due to be released in June 2020, and will be supported until June 2023.
MediaWiki 1.33 has the same supported PHP version of 7.0 (which is unsupported upstream), incase you need longer to upgrade your systems. Whereas MediaWiki 1.34 requires PHP 7.2.9 or later.
