2021-05-30: MediaWiki 1.36.0 available
MediaWiki is the software that runs Wikipedia and thousands of other wiki sites. Mediawiki 1.36.0 was released on 27th of May.
Release notes can be found on https://www.mediawiki.org/wiki/MediaWiki_1.36
- The logo of MediaWiki has changed. This means that the "Powered By MediaWiki" button shown in the skin footer will be different.
- All HTML5 named entities are now accepted in wikitext.
- MediaWiki now supports 2048 pixel image size in the file description page's alternate size.
A note on upgrading
- MediaWiki 1.36 now requires the PHP internationalization extension (commonly referred to as Intl, ext-intl, or php-intl).
- The MediaWiki:Autoblock_whitelist block exemption control has been moved to MediaWiki:Block-autoblock-exemptionlist. If you use this feature, please move the MediaWiki:Autoblock_whitelist page.
- $wgExtensionFunctions is sometimes used to change configuration settings. This is not safe; extension functions are run relatively late, some services are already initialized by that point and so they use the old configuration. Changes in 1.36 make this kind of breakage even more common. You can use the MediaWikiServices hook instead. (In the future there might be a dedicated hook for configuration changes.)
- The MediaWiki update script, maintenance/update.php, used to accept `--nopurge` as an option to prevent clearing caches stored in the database during upgrade. This is no longer encouraged, and the option has been removed.
I've done the upgrade myself, and though fairly straight-forward I suggest you start fresh and move back images/*, LocalSettings.php and then re-install any extensions you are using. Some are not compatible with the new MediaWiki version, and others will need updates to work.
