*Updates for editors*

   - The Wikipedia iOS app has launched an A/B/C test of improvements made
   to the tabbed browsing feature for select regions and languages. The test,
   named “More dynamic tabs”, explores new tab experiences and includes “Did
   you know” and “Because you read” article recommendations. You can read
   more on the project page

   the CampaignEvents extension can now use Event Registration
   <https://meta.wikimedia.org/wiki/Special:MyLanguage/Event_Center/Registration>
without
   the Event Organizer right. This feature lets organizers enable
   registration, manage participants, and lets users register with one click
   instead of signing event pages.

*Updates for technical contributors*

   - The CampaignEvents extension will be deployed to all remaining wikis
   during the week of 17 November 2025. The extension currently includes three
   features: Event Registration, Collaboration List, and Invitation List. For
   this rollout, Invitation List will not be enabled on Wikifunctions and
   MediaWiki unless requested by those communities. Visit the deployment
   page to learn more
   <https://meta.wikimedia.org/wiki/Special:MyLanguage/CampaignEvents/Deployment_status>
   .
   - The SwaggerUI-based REST sandbox experience is now live on all wiki
   projects. The sandbox can be accessed through the Special:RestSandbox
   <https://meta.wikimedia.org/wiki/Special:RestSandbox> page. Please
   report any issues to the MediaWiki Interfaces team board, or join the
   discussion on the project launch
   <https://www.mediawiki.org/wiki/Special:MyLanguage/MediaWiki_Interfaces_Team/Feature_Feedback/REST_Sandbox>
    page. [2] <https://phabricator.wikimedia.org/project/board/6931/>
   - Transform endpoints with a trailing slash path in the MediaWiki REST
   API are now marked as deprecated. They will remain functional during this
   time, but removal is expected by the end of January 2026. All API users
   currently calling them are encouraged to transition to the non-trailing
   slash versions. Both endpoint variations can be found and tested
using the REST
   Sandbox
   <https://test.wikipedia.org/w/index.php?api=mw-extra&title=Special%3ARestSandbox>.
   See the MediaWiki REST API Deprecation
   <https://www.mediawiki.org/wiki/API/Deprecation> page for more detailed
   information about the API deprecation policies and procedures.
   - A dedicated changelog now exists for the MediaWiki REST API
   <https://www.mediawiki.org/wiki/API:REST_API/Changelog>. The changelog
   provides an overview of these changes, making it easier for developers to
   keep track of improvements and iterations. Announcements will also continue
   to flow through the standard communication channels, including Tech News
   and email distribution lists, but can now be more easily referenced from a
   central location. If you have feedback about the style, structure, or
   content of this changelog, please join the discussion
   <https://www.mediawiki.org/wiki/API_talk:REST_API/Changelog>.
   - Administrators can delete the tracking category which was previously
   added by the JsonConfig extension, as it is no longer used. See the
   categories linked from Q130635582
   <https://www.wikidata.org/wiki/Q130635582#sitelinks-wikipedia>. It is OK
   if there are still pages listed in the category as that is just a caching
   issue, and they will be automatically cleared out the next time each page
   is edited. [3] <https://phabricator.wikimedia.org/T378352>
