The operations team completed the upgrade several hours ago. The upgrade from MediaWiki v1.39 to v1.43 comes with a number of changes, mostly behind the scenes. The most notable change is support for dark mode – but now we need help fixing individual pages and templates. Artistically inclined wiki editors may also be interested in new support for the filter property in CSS. See the v1.42 and v1.43 release notes for details.
