*Updates for editors*

- The tray shown on Special:Diff https://meta.wikimedia.org/wiki/Special:Diff in mobile view has been redesigned. It is now collapsed by default, and incorporates a link to undo the edit being viewed, making it easier for mobile editors and reviewers to take action while keeping the interface uncluttered. [1] https://phabricator.wikimedia.org/T402297 - The Global Watchlist https://meta.wikimedia.org/wiki/Special:GlobalWatchlist lets you view your watchlists from multiple wikis on one page. The extension https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:GlobalWatchlist continues to improve — it now automatically determines the text direction (ensuring correct display of sites with unusual domain names) and shows detailed descriptions for log actions. Later this week, a new permanent link for page creations and CSS classes for each entry element will be added.

For example, the previously observed issue in Vector 2022, where anchor link targets were obscured by the sticky header, has now been addressed. [6] https://phabricator.wikimedia.org/T406114

*Updates for technical contributors*

- As mentioned in the October 2025 deprecation announcement https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/2025/44, MediaWiki Interfaces team will begin sunsetting all transform endpoints containing a trailing slash from the MediaWiki REST API the week of January 26. Changes are expected to roll out to all wikis on or before January 30th. All API users currently calling them are encouraged to transition to the non-trailing slash versions. Both endpoint variations can be found, compared, and tested using the REST Sandbox https://test.wikipedia.org/wiki/Special:RestSandbox. If you have questions or encounter any problems, please file a ticket in Phabricator to the #MW-Interfaces-Team board https://phabricator.wikimedia.org/project/view/6931/. - Interactive reference documentation for the Wikimedia REST API https://www.mediawiki.org/wiki/Special:MyLanguage/Wikimedia_REST_API has moved. Requests to API docs previously hosted through RESTBase https://www.mediawiki.org/wiki/Special:MyLanguage/RESTBase (e.g.: https://en.wikipedia.org/api/rest_v1/) are now redirected to the REST Sandbox https://en.wikipedia.org/wiki/en:Special:RestSandbox. - The WMF Wikidata Platform team https://www.mediawiki.org/wiki/Special:MyLanguage/Wikidata_Platform (WDP) has published its January 2026 newsletter https://www.wikidata.org/wiki/Special:MyLanguage/Wikidata:Wikidata_Platform_team/Newsletter. It includes updates on the legacy full-graph endpoint decommissioning, the User-Agent policy change, the monthly Blazegraph migration office hours, and efforts to reduce regressions caused by the legacy endpoint shutdown. As a reminder, you can subscribe to the WDP newsletter https://meta.wikimedia.org/wiki/Special:MyLanguage/Global_message_delivery/Targets/WDP_team_updates ! - Detailed code updates later this week: MediaWiki https://www.mediawiki.org/wiki/MediaWiki_1.46/wmf.12

*Meetings and events*

- The Wikimedia Hackathon Northwestern Europe 2026 https://www.mediawiki.org/wiki/Wikimedia_Hackathon_Northwestern_Europe_2026 will take place on 13-14 March 2026 in Arnhem, the Netherlands. Applications opened mid-December and will close soon or when capacity is reached. It's a two-day, technically oriented hackathon bringing together Wikimedians from the region. Hope to see you there!
