Latest *tech news https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News* from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/2026/09 are available.

*Weekly highlight*

- Reference Check https://www.mediawiki.org/wiki/Special:MyLanguage/Edit_check/Reference_Check has been deployed to English Wikipedia, completing its rollout across all Wikipedias. The feature prompts newcomers to add a citation before publishing new content, helping reduce common citation-related reverts and improve verifiability. In A/B testing, the impact was substantial: newcomers shown Reference Check were approximately 2.2 times more likely to include a reference on desktop and about 17.5 times more likely on mobile web.

*Updates for editors*

- The InterwikiSorting extension https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:InterwikiSorting, which allowed for the sorting of interwiki links https://meta.wikimedia.org/wiki/Special:MyLanguage/Interwiki_sorting_order, has been undeployed from Wikipedia. As a result, editors who had enabled interwiki link sorting in non-compact mode (full list format) will now see links reordered. The links moving forward will be listed in the alphabetical order of language code. [2] https://phabricator.wikimedia.org/T253764 - Later this week, people who are editing a page-section using the mobile visual editor, will notice a new "Edit full page" button. When tapped, you will be able to edit the entire article. This helps when the change you want to make is outside the section you initially opened. [3] https://phabricator.wikimedia.org/T387175[4] https://phabricator.wikimedia.org/T409112 - The Reader Experience team https://www.mediawiki.org/wiki/Special:MyLanguage/Readers/Reader_Experience is inviting editors to assess whether dark mode should still be considered "beta" on their wiki, based on their experience of how well it functions on desktop and mobile. If the feature is deemed mature, editors can update the interface messages in MediaWiki:skin-theme-description and MediaWiki:Vector-night-mode-beta-tag to indicate that dark mode is ready and no longer considered beta. - The improved Activity tab https://www.mediawiki.org/wiki/Wikimedia_Apps/Team/iOS/Activity_Tab which displays user-insights is now available to all users of the Wikipedia iOS app (version 7.9.0 and later). Following earlier A/B testing that showed higher account creation among users with access to the feature, it has been rolled out to 100% of users along with some updates. The Activity tab now shows your edited articles in the timeline, offers editing impact insights like contribution counts and article view trends, and customization options to improve in-app experience for users. - View all 21 community-submitted tasks that were resolved last week https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/Recently_resolved_community_tasks. For example, a bug that prevented DiscussionTools https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:DiscussionTools from working on mobile has now been fixed, restoring full functionality.

*Updates for technical contributors*

- 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 that makes this possible continues to improve. The latest upgrade is the inclusion of a new hook https://www.mediawiki.org/wiki/Extension:GlobalWatchlist#hook, ext.globalwatchlist.rebuild, which fires after each watchlist rebuild. This allows you to run gadgets and user scripts for the Special page.
