Graph Extension update: Foundation developers have completed upgrading the visualization software to Vega5. Existing community graphs based on Vega2 are no longer compatible. Communities need to update local graphs and templates, and shared lua modules like de:Modul:Graph. The Vega Porting guide provides the most comprehensive detail on migration from Vega2 and here is an example migration. Vega5 has currently just been enabled on mediawiki.org to provide a test environment for communities.
Changes later this week
The new version of MediaWiki will be on test wikis and MediaWiki.org from 9 May. It will be on non-Wikipedia wikis and some Wikipedias from 10 May. It will be on all wikis from 11 May (calendar).
Until now, all new OAuth apps went through manual review. Starting this week, apps using identification-only or basic authorizations will not require review.
During the next year, MediaWiki will stop using IP addresses to identify logged-out users, and will start automatically assigning unique temporary usernames.

You can [m:Talk:IP Editing: Privacy Enhancement and Abuse Mitigation#What should it look like? join the discussion] about the [m:Special:MyLanguage/IP Editing: Privacy Enhancement and Abuse Mitigation/Updates#What will temporary usernames look like? format of the temporary usernames].
There will be an A/B test on 10 Wikipedias where the Vector 2022 skin is the default skin. Half of logged-in desktop users will see an interface where the different parts of the page are more clearly separated. You can read more.
jquery.tipsy will be removed from the MediaWiki core. This will affect some user scripts. Many lines with .tipsy( can be commented out. OO.ui.PopupWidget can be used to keep things working like they are now. You can read more and read about how to find broken scripts.
