*Weekly highlight* - The Wikimedia Foundation has shared the latest draft update to their annual plan <https://meta.wikimedia.org/wiki/Special:MyLanguage/Wikimedia_Foundation_Annual_Plan/2025-2026> for next year (July 2025–June 2026). This includes an executive summary <https://meta.wikimedia.org/wiki/Special:MyLanguage/Wikimedia_Foundation_Annual_Plan/2025-2026> (also on Diff <https://diff.wikimedia.org/2025/04/25/sharing-the-wikimedia-foundations-2025-2026-draft-annual-plan/>), details about the three main goals <https://meta.wikimedia.org/wiki/Special:MyLanguage/Wikimedia_Foundation_Annual_Plan/2025-2026/Goals> (Infrastructure <https://meta.wikimedia.org/wiki/Special:MyLanguage/Wikimedia_Foundation_Annual_Plan/2025-2026/Product_%26_Technology_OKRs>, Volunteer Support <https://meta.wikimedia.org/wiki/Special:MyLanguage/Wikimedia_Foundation_Annual_Plan/2025-2026/Goals/Volunteer_Support>, and Effectiveness <https://meta.wikimedia.org/wiki/Special:MyLanguage/Wikimedia_Foundation_Annual_Plan/2025-2026/Goals/Effectiveness>), global trends <https://meta.wikimedia.org/wiki/Special:MyLanguage/Wikimedia_Foundation_Annual_Plan/2025-2026/Global_Trends>, and the budget <https://meta.wikimedia.org/wiki/Special:MyLanguage/Wikimedia_Foundation_Annual_Plan/2025-2026/Budget_Overview> and financial model <https://meta.wikimedia.org/wiki/Special:MyLanguage/Wikimedia_Foundation_Annual_Plan/2025-2026/Financial_Model>. Feedback and questions are welcome on the talk page <https://meta.wikimedia.org/wiki/Talk:Wikimedia_Foundation_Annual_Plan/2025-2026> until the end of May. *Updates for editors* - For wikis that have the CampaignEvents extension enabled <https://meta.wikimedia.org/wiki/Special:MyLanguage/CampaignEvents/Deployment_status>, two new feature improvements have been released: - Admins can now choose which namespaces are permitted for Event Registration <https://meta.wikimedia.org/wiki/Special:MyLanguage/Event_Center/Registration> via Community Configuration <https://www.mediawiki.org/wiki/Special:MyLanguage/Community_Configuration> (documentation <https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Extension:CampaignEvents/Registration/Permitted_namespaces>). The default setup is for event registration to be permitted in the Event namespace, but other namespaces (such as the project namespace or WikiProject namespace) can now be added. With this change, communities like WikiProjects can now more easily use Event Registration for their collaborative activities. - Editors can now transclude <https://www.mediawiki.org/wiki/Special:MyLanguage/Transclusion> the Collaboration List on a wiki page (documentation <https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Extension:CampaignEvents/Collaboration_list/Transclusion>). The Collaboration List is an automated list of events and WikiProjects on the wikis, accessed via Special:AllEvents (example <https://en.wikipedia.org/wiki/en:Special:AllEvents>). Now, the Collaboration List can be added to all sorts of wiki pages, such as: a wiki mainpage, a WikiProject page, an affiliate page, an event page, or even a user page. - [image: Recurrent item] View all 27 community-submitted tasks that were resolved last week <https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/Recently_resolved_community_tasks> . *Updates for technical contributors* - Developers who use the moment library in gadgets and user scripts should revise their code to use alternatives like the Intl library or the new mediawiki.DateFormatter library. The moment library has been deprecated and will begin to log messages in the developer console. You can see a global search for current uses, and ask related questions in this Phabricator task <https://phabricator.wikimedia.org/T392532>. - Developers who maintain a tool that queries the Wikidata term store tables (wbt_*) need to update their code to connect to a separate database cluster. These tables are being split into a separate database cluster. Tools that query those tables via the wiki replicas must be adapted to connect to the new cluster instead. Documentation and related links are available <https://wikitech.wikimedia.org/wiki/News/2025_Wikidata_term_store_database_split>.

It includes updates on preparing to expand the deployment to additional wikis as soon as this week (starting May 6) and scaling up over the following weeks, plus exploring filtering and transforming source data. *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/2025/19> • 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>.* -- Nick "Quiddity" Wilson (he/him) Movement Communications Specialist Wikimedia Foundation
