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/2026/25 are available.

*Weekly highlight*

- The Reader Growth team https://www.mediawiki.org/wiki/Special:MyLanguage/Readers/Reader_Growth has launched an Image Browsing https://www.mediawiki.org/wiki/Special:MyLanguage/Readers/Reader_Growth/Image_Browsing beta feature on the mobile web version of all Wikipedias. The feature shows an image carousel at the top of articles with 3 or more images. Editors can configure this feature with the following controls: to hide a specific image from a page, either use class=notpageimage excluding it from thumbnail previews, or class=noviewer excluding it from MediaViewer. The carousel can also be disabled from a page entirely, with the magic word __NOMEDIAVIEWERCAROUSEL__. To submit feedback or flag bugs, please visit the project page https://www.mediawiki.org/wiki/Talk:Readers/Reader_Growth/Image_Browsing . - Wikitables https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Tables#class=%22wikitable%22 can now be sorted in descending order https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Sortable_tables#Forcing_the_initial_sort_direction on the first click by adding data-sort-order="desc" to the header cell. Previously, by default, clicking a column header for the first time sorts it in ascending order. This addition to a Wikitable gives it more control and flexibility, while the default behavior for subsequent clicks remains unchanged. [1] https://phabricator.wikimedia.org/T398416

*Updates for editors*

- The Article guidance https://www.mediawiki.org/wiki/Special:MyLanguage/Article_guidance feature is currently being tested with some editors creating new articles on the Simple English, French, and Turkish Wikipedias. The experiment will soon begin on the Arabic and Bangla Wikipedias as well. This feature https://en.wikipedia.org/wiki/simple:Special:NewArticle gives editors community-curated guidance to help them create articles that follow community standards. Experienced editors can continue creating or adapting outlines for specific article types that are commonly created by less experienced contributors. The outlines guide less experienced editors in creating high-quality articles. A quick guide to markups used in outlines can be found on this page https://www.mediawiki.org/wiki/Special:MyLanguage/Article_guidance/Test_feature_guide#Markups_in_outlines . Example outlines https://en.wikipedia.org/wiki/simple:Wikipedia:Article_Guidance that can be adapted and instructions for how to adapt them are on this section https://www.mediawiki.org/wiki/Special:MyLanguage/Article_guidance#Adapting_a_sample_outline_in_a_Wikipedia of the project page. - Wikis that wish to replace the "indefinitely" button in Special:Block for temporary accounts (for example, wikis that block temporary users only until account expiration) will be able to do so by creating MediaWiki:ipb-indefinite-expiry-temporary-account https://meta.wikimedia.org/wiki/MediaWiki:Ipb-indefinite-expiry-temporary-account with the block duration they want.

*Updates for technical contributors*

- By the end of June, a valid user-agent string will be required for automated dumps downloads from the dumps.wikimedia.org website. Automated requests that provide a generic or empty user-agent will be blocked. This extends enforcement https://phabricator.wikimedia.org/T400119 of the long standing user-agent policy https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Wikimedia_Foundation_User-Agent_Policy. Access to dumps through Wikimedia Cloud Services will not change. - The roll out of global API rate limits https://www.mediawiki.org/wiki/Wikimedia_APIs/Rate_limits is now complete, with limits enforced across all APIs and at the documented levels for all groups. Bots running in Toolforge/WMCS or with the bot user right on any wiki remain exempt. All bots should continue to follow the documented best practices to avoid being rate limited. - The API Portal wiki https://api.wikimedia.org/wiki/Main_Page will be read only starting this week (June 15-18). The following week (June 22-25), all API Portal wiki URLs will redirect to Wikimedia APIs on mediawiki.org https://www.mediawiki.org/wiki/Wikimedia_APIs. Learn more on the project page https://wikitech.wikimedia.org/wiki/API_Portal/Deprecation. - Detailed code updates later this week: MediaWiki https://www.mediawiki.org/wiki/MediaWiki_1.47/wmf.7

*Meetings and events*

- On June 17th at 6pm UTC the WMF will be holding Discord call focused on a code review.
