*Weekly highlight*

- The Editing team wants to compile a list of templates, jargon terms, and policies used in edit summaries when a copyright violation is removed. This will help them identify the number of edits reverted due to copyright issues. We invite community members from the following Wikis to list these terms in T402601 https://phabricator.wikimedia.org/T402601, or to share their list with Trizek_(WMF) https://meta.wikimedia.org/wiki/User:Trizek_(WMF): Arabic Wikipedia, Czech Wikipedia, German Wikipedia, English Wikipedia, Spanish Wikipedia, Persian Wikipedia, French Wikipedia, Hebrew Wikipedia, Indonesian Wikipedia, Italian Wikipedia, Japanese Wikipedia, Korean Wikipedia, Dutch Wikipedia, Polish Wikipedia, Portuguese Wikipedia, Turkish Wikipedia, Ukrainian Wikipedia, Vietnamese Wikipedia, Chinese Wikipedia. This project is open until September 9th 2025.

*Updates for editors*

- The CampaignEvents extension https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Extension:CampaignEvents has been enabled for all Wikisources. The extension makes it easier to organize and participate in collaborative activities, like edit-a-thons and WikiProjects, on the wikis. The extension has three features: Event Registration https://meta.wikimedia.org/wiki/Special:MyLanguage/Event_Center/Registration , Collaboration List https://meta.wikimedia.org/wiki/Special:MyLanguage/CampaignEvents/Collaboration_list, and Invitation List https://meta.wikimedia.org/wiki/Special:MyLanguage/Connection_Team/Invitation_list. To request the extension for your wiki, visit the Deployment information page. [1] https://meta.wikimedia.org/wiki/CampaignEvents/Deployment_status#How_to_Request_the_CampaignEvents_Extension_for_your_wiki - The lists in the footer of the editing interface, such as "Templates used on this page," will now be organized into columns when there is enough space. This enhancement minimizes scrolling when editing lengthy articles on Wikipedia. [2] https://phabricator.wikimedia.org/T401066 - On September 3rd, 2025 we will increase the sampling percentages of our group by toggle experiment https://www.mediawiki.org/wiki/Special:MyLanguage/Moderator_Tools/Watchlist/Experiment#Scope_of_the_experiment of the Special:RecentChanges, Special:Watchlist, and Special:RelatedChanges pages on the Chinese, French, and Portuguese Wikipedias to 100 percent, allowing more editors to be part of this experiment. This adjustment is intended to ensure we have sufficient data to make informed decisions when evaluating the experiment results. [3] https://phabricator.wikimedia.org/T402958 [4] https://phabricator.wikimedia.org/T396789 - Upon clicking an empty search bar, logged-out users will see suggestions of articles for further reading on English Wikipedia beginning the week of September 22. The feature will be available on both desktop and mobile. All non-English wikis received this change in June and July. The goal is to make it easier for users to find articles.

*In depth*

- Wikifunctions now has a new capability called "lightweight enumeration types", an enumeration type is simply a fixed set of values that's in the type's definition. This capability makes it quick and easy to define such a type, and allows for the reuse of values that are already present in Wikidata. Here is a newsletter https://www.wikifunctions.org/wiki/Special:MyLanguage/Wikifunctions:Status_updates/2025-07-19 to learn more. - The latest Readers Newsletter https://www.mediawiki.org/wiki/Special:MyLanguage/Readers/Newsletter_updates#August_2025:_Newsletter_#1 is now available. This edition includes: the formation of two new teams — Reader Growth and Reader Experience; insights into declining pageviews and account creations; highlights from the Wikimania Nairobi panel on improving the reading experience; upcoming experiments to engage new and existing readers; and more.
