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/2025/37 are available.

*Weekly highlight*

- The Editing team is working on a new check: Paste check https://www.mediawiki.org/wiki/Special:MyLanguage/Paste_check. This check informs newcomers who paste text into Wikipedia that the content might not be accepted. This check is an effort to increase the likelihood that the new content people are adding to Wikipedia is aligned with the Movement's commitment to offering information under a free content license. This check will soon be tested at a few wikis. If your community is interested in this test, please tell us in this task https://phabricator.wikimedia.org/T403680, or contact the team https://www.mediawiki.org/wiki/Talk:Edit_check.

*Updates for editors*

- Later this week, users of the "Improved Syntax Highlighting" beta feature https://meta.wikimedia.org/wiki/Special:Preferences#mw-prefsection-betafeatures will be able to use a linting tool https://en.wikipedia.org/wiki/en:Lint_(software) to see errors or other potential problems in wikitext in real time. See the help page for more information https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Extension:CodeMirror#Linting. [1] https://phabricator.wikimedia.org/T381577 - When browsing a wiki (like en.wikipedia.org), the software responds in one of two ways: a desktop page, or a redirect to a mobile version on an "m" domain (like en.m.wikipedia.org). Over the next three weeks, MediaWiki will start displaying the mobile version to mobile devices directly on the standard domain, without this redirect. This change does not affect existing m-dot URLs, or the "Desktop view" opt-out. Learn more https://www.mediawiki.org/wiki/Requests_for_comment/Mobile_domain_sunsetting/2025_Announcement. [2] https://phabricator.wikimedia.org/T214998 - When an edit changes the categories of a page, the changes to the category membership counts are now happening asynchronously. This improves the speed of saving edits, especially when moving many pages to or from the same category, and reduces the risk of site outages, but it means that the counts can show outdated information for a few minutes. [3] https://phabricator.wikimedia.org/T365303 - Edits on Wikidata to qualifiers (properties and values) and references (properties and values) in a Wikidata item statement will now not add entries to the RecentChanges or Watchlist pages on all other Wikis. This is a temporary change to improve performance while other solutions are created. Wikidata's own pages remain unchanged. Learn more https://meta.wikimedia.org/wiki/Wikidata_For_Wikimedia_Projects/Reduce_change_propagation_noise#Phase_1:_Turn_off_(temporarily)_Qualifiers_and_References_Wikidata_edits_to_the_Recent_Changes_tables. [4] https://phabricator.wikimedia.org/T401286[5] https://phabricator.wikimedia.org/T400698 - Japanese-language wikis have had a major upgrade to the way that search works. The new search should generally give more accurate and more relevant search results. [6] https://phabricator.wikimedia.org/T318269 - View all 31 community-submitted tasks that were resolved last week https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/Recently_resolved_community_tasks .
