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.
Autoconfirmed users on small and medium wikis with the CampaignEvents extension can now use Event 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.
View all 31 community-submitted tasks that were resolved last week. For example, the issue of flashing colors when holding or pressing the arrow keys under the dark mode settings in Vector 2022 has been fixed. [1]
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.
The SwaggerUI-based REST sandbox experience is now live on all wiki projects. The sandbox can be accessed through the Special:RestSandbox page. Please report any issues to the MediaWiki Interfaces team board, or join the discussion on the project launch page. [2]
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. See the MediaWiki REST API Deprecation page for more detailed information about the API deprecation policies and procedures.
A dedicated changelog now exists for the MediaWiki REST API. 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.
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. 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]
