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/2026/19> are available.
*Weekly highlight* - The Article guidance <https://www.mediawiki.org/wiki/Special:MyLanguage/Article_guidance> team invites experienced editors of pilot Wikipedias <https://www.mediawiki.org/wiki/Special:MyLanguage/Article_guidance/Pilot_wikis_and_collaborators>—Arabic, Bangla, Japanese, Portuguese, Persian, Turkish, Simple English, Spanish, and French—to help translate and adapt sample outlines <https://b24e11a4f1.catalyst.wmcloud.org/wiki/Category:Pages_using_article_guidance>. These outlines will guide editors in creating clear, well-structured, and policy-compliant articles when using the feature <https://b24e11a4f1.catalyst.wmcloud.org/wiki/Special:NewArticle> once it is launched in May 2026. Simple instructions <https://www.mediawiki.org/wiki/Special:MyLanguage/Article_guidance#Adapting_a_sample_outline_in_a_Wikipedia> on how to translate and adapt the outlines are available. *Updates for editors* - The Product and Technology Advisory Council <https://meta.wikimedia.org/wiki/Special:MyLanguage/Product_and_Technology_Advisory_Council> has published draft recommendations <https://meta.wikimedia.org/wiki/Special:MyLanguage/Product_and_Technology_Advisory_Council/May_2026_draft_PTAC_recommendation_for_feedback> on a model that affiliates can follow when contributing to the technical space. Community members are invited to provide feedback on the recommendation until May 8th on the talk page <https://meta.wikimedia.org/wiki/Talk:Product_and_Technology_Advisory_Council/May_2026_draft_PTAC_recommendation_for_feedback> . - The number of available thumbnail size preferences in MediaWiki is being reduced to three standardized options—Small (180px), Regular (250px), and Large (400px), as part of ongoing efforts to improve performance and reduce strain on thumbnail services. As a result, existing preferences will be mapped to the nearest new size (for example, smaller selections like 120px or 150px will render at 180px, while larger ones like 300px or 360px will render at 400px). The preferences interface will soon be updated to reflect these changes, and users who wish to opt out or provide feedback can do so. [1] <https://phabricator.wikimedia.org/T424909> - From now on, even when a permission expires automatically, users will receive an Echo notification similar to the standard notification for permission changes. There is a difference between this and Global reminder bot <https://meta.wikimedia.org/wiki/Special:MyLanguage/Global_reminder_bot> in that the latter reminds users a week *before* the rights are due to expire, so that they can renew the rights. - View all 32 community-submitted tasks that were resolved last week <https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/Recently_resolved_community_tasks>. For example, the problem where the ULS language selector in Special:Translate <https://meta.wikimedia.org/wiki/Special:Translate> would scroll vertically when it shouldn't, has been resolved. Previously, when users opened the "Translate to English" dropdown and typed certain inputs, the dialog would scroll vertically by a few pixels even when there was enough space to display all results. The dropdown no longer shifts unnecessarily when filtering languages. [2] <https://phabricator.wikimedia.org/T358864> - The Global Watchlist <https://meta.wikimedia.org/wiki/Special:GlobalWatchlist>, which lets you view your watchlists from multiple wikis on a single page, continues to improve. For example, watchlists for Wikibase sites such as Wikidata <https://www.wikidata.org/wiki/> now support EntitySchema <https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:EntitySchema> elements for better tracking. The Live Updates mode now refreshes the special page every 60 seconds to comply with the updated global API rate limits <https://www.mediawiki.org/wiki/Special:MyLanguage/Wikimedia_APIs/Rate_limits> for improved real-time responsiveness. Additionally, a directionality bug that displayed links as "changes 3" instead of "3 changes" in mixed-direction lists has been fixed. [3] <https://phabricator.wikimedia.org/T415450>[4] <https://phabricator.wikimedia.org/T424422>[5] <https://phabricator.wikimedia.org/T418091> *Updates for technical contributors* - The second phase of global API rate limits <https://www.mediawiki.org/wiki/Special:MyLanguage/Wikimedia_APIs/Rate_limits> has been rolled out to reduce the impact of AI crawlers <https://diff.wikimedia.org/2026/03/26/quo-vadis-crawlers-progress-and-whats-next-on-safeguarding-our-infrastructure/> and ensure fair, sustainable access to Wikimedia resources, prioritising human and mission-aligned traffic. Limits <https://www.mediawiki.org/wiki/Special:MyLanguage/Wikimedia_APIs/Rate_limits#Limits> have been shifted from per-hour to per-minute, producing smoother traffic patterns and more predictable API load. Community users are not expected to be affected, and no action is required. Early indications show some User-Agent-based requestors are adjusting behaviour, and around 64% of automated API traffic has been identified. Monitoring continues, and Wikimedia Enterprise remains available for commercial support. - Detailed code updates later this week: MediaWiki <https://www.mediawiki.org/wiki/MediaWiki_1.46/wmf.27> *Tech news <https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News> prepared by Tech News writers <https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/Writers> and posted by bot <https://meta.wikimedia.org/wiki/Special:MyLanguage/User:MediaWiki_message_delivery> • Contribute <https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News#contribute> • Translate <https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/2026/19> • Get help <https://meta.wikimedia.org/wiki/Tech> • Give feedback <https://meta.wikimedia.org/wiki/Talk:Tech/News> • Subscribe or unsubscribe <https://meta.wikimedia.org/wiki/Global_message_delivery/Targets/Tech_ambassadors>.*
