* As a part of the MediaWiki rollout the Typography Refresh beta feature will move from VectorBeta extension/Beta Feature to the Vector skin in MediaWiki core. This effectively updates the default skin for all users with improved readability. ** See the summary of changes: https://www.mediawiki.org/wiki/Typography_refresh#Summary_of_changes ** This will roll out with the 1.23wmf20 branch mentioned above, which means it will gradually roll out to all wikis following the normal progression (testwikis & mediawiki.org on Thursday -> non-wikipedias (eg Commons etc) on Tuesday -> All wikis following Thursday).

Thanks, and as always, questions welcome,
