Weekly highlight

• The process for this year’s Community Wishlist has been published, incorporating community feedback. The wish submission process will end on November 8. This year, a working group (open for volunteering) that includes community members familiar with the technical aspect of our wikis alongside Wikimedia Foundation staff, will take care of the triage process. The triage is expected to be completed by late November. Votes for wishes will start in January.

Updates for editors

• Editors using the visual editor will now see a warning when they paste text that is likely to have initially been copied from one of five external generative AI chatbots into Wikipedia. This feature is known as LLM Paste Check. It is a type of Edit Check that is community configurable. The check looks for markers in the copied HTML and is not using content watermark detection. Edits will also be tagged so that patrollers can review them more closely. The feature helps newcomers add content that respects Wikipedia’s policies and makes it easier for experienced editors to identify problematic edits. Communities with local policies about LLM usage can adjust the wording and policy that is linked. The team apologizes that this was rolled out without a delay for translations.
• Editors can now easily access the web visual editor directly from the iOS and Android apps. When opening the editor, users will be given a choice between visual editing and source editing. If they choose visual editing, they will be sent to a mobile web window in their phone's browser. After completing their edit, a banner will give them the option to return to the app. This enables readers to make quick contributions while casually reading.
• Users of the Wikipedia Android and iOS apps will now see a one-time account creation prompt after they have used the app for two consecutive weeks. This prompt explains the benefits of having an account. It is intended to help more casual readers become logged-in users who return to the apps regularly.
• Editors on group1 wikis, including Wikiquote, Wikibooks, Wikiversity, Wikivoyage, and Wikisource, will no longer see notifications on Recent Changes and Watchlist when a link to another language version of a page is added, removed, or changed in its Wikidata item. This change will begin on October 5 at 07:00 UTC as a two-week trial to reduce high-volume, low-value notifications and make important changes easier to identify. Editors who rely on these notifications can read more on the project page and share feedback or concerns on the talk page.
• View all 36 community-submitted tasks that were resolved last week. For example, an issue where mentors who removed themselves from the mentorship program could still have mentees assigned to them and receive questions, has now been fixed. Mentees will now be reassigned when a mentor leaves the program.

Updates for technical contributors

• Wikimedia Brasil has published its Development Best Practices Framework (ABPD). It is a guide for staff, contractors and volunteers building technical tools and projects. It covers the project lifecycle, security, accessibility, personal data protection and responsible AI use, and explains how movement-wide guidelines were adapted to a local context. They encourage other affiliates to reuse it and adapt it. Read more in the Diff post.
• A new, canonical base URL for Wikimedia APIs will soon be introduced. The new canonical route follows a {projectName}/api/ pattern and will act as an alternative path for current REST APIs (for example: {projectName}/w/rest.php/). Both versions will be callable for all existing APIs, but the new structure will be the preferred path for newly created API modules. This change will be non-breaking for most users. The existing pathways will remain available for all existing endpoint requests. However, some endpoints may return URLs following the new pattern in response bodies. Changes will be available on test wiki first, with the rollout expected to cover all wikis by the end of October.
• Detailed code updates later this week: MediaWiki.

Weekly highlight

• Starting October 13, wikis can change the default pattern for auto-generated reference names in VisualEditor (currently <ref name=":1" />). They will be able to use human-readable, content-based reference names that are more helpful to contributors using the source editor (e.g. <ref name="Miller2026-1" />). VisualEditor reference name patterns can be defined using MediaWiki system messages, JSON, templates and modules (more information). Admins can enable these changes via community configuration. This is a community wish implemented by WMDE Technical Wishes.
• Sub-referencing is a new MediaWiki feature that allows editors to reuse references with different details. It will be deployed to English Wikipedia on October 14 and to remaining Wikimedia Foundation wikis by end of October (likely October 21). The FAQ lists possible actions to take on your wiki to support the deployment. This is a long-standing community wish implemented by WMDE Technical Wishes.

Updates for editors

• Moderator Tools will be removing the list view of the Watchlist and defaulting everyone to the changelog view. Previously, there were two versions of how the Watchlist is shown to mobile web users: the list view, where editors could see watched articles in a list format, and the changelog view, where editors could see changes to watched articles in a log format, controlled by a user's Advanced Mobile Control settings. This has created issues for code-base maintenance: two different displays means two sets of code to manage. By defaulting to the changelog view, we are simplifying the codebase and avoiding the likelihood of missing bugs.
• The Wikipedia Android app is testing a way to listen to article introductions in the “For you” feed. A text-to-speech model reads the existing article text aloud without rewriting it or adding any content. The 30-day experiment will begin in the Wikipedia Beta app during the third week of September, then move to the regular Wikipedia Android app in October for a limited group of eligible users. A small portion of app users (those with English feeds and at least one topic interest) will have access to the feature. This experiment is part of broader efforts to give app readers options in how they consume content in order to deepen engagement and user retention. Learn more and share feedback.
• CodeMirror syntax highlighting was enabled by default for all logged out and newly registered users on the English Wikipedia on September 14. With no signs of adverse effects, the same change is being proposed to be made globally across all wikis in a few weeks. If you have concerns or feedback, or if your wiki would like to opt out, please see the help page.
• Wikidata mobile statement editing of all datatypes will be officially launched on October 13, when it will be removed from Wikidata beta features and become available to all editors. Users can report bugs and share feedback.
• Last week, language link changes were removed from Recent Changes and Watchlist feeds on Wikivoyage, Wikisource, Wikiversity, Wikiquote and Wiktionary. As no adverse effects have been observed, the Wikidata For Wikimedia Projects plans to roll out this change globally to all Wikipedias. This is scheduled for October 13 at 07:00 UTC, after which editors will no longer see when a link to another language version of a page is added, removed, or changed in its Wikidata item. Editors who rely on these notifications can read more on the project page and share feedback or ask to opt out their wiki on the talk page.
• View all 28 community-submitted tasks that were resolved last week. For example, an issue where accidentally touching the graph while scrolling on the Pageviews tool on mobile could unintentionally zoom in has now been fixed. Click-and-drag zoom is now disabled on touch devices.

Updates for technical contributors

• There are three major changes coming to dumps: the legacy content dumps deprecated in January 2026 will now be sunset, the replacement MediaWiki Content File Exports will be delayed to implement a “safety buffer”, and they are now also available as 7zip-compressed files. Users will need to switch the URL they download their dump from. For more information, timeline and migration instructions, see Legacy content dumps sunset.
• Detailed code updates later this week: MediaWiki

In depth

• The Wikimedia Foundation discovered unauthorized activity by OpenAI agents on Wikimedia projects, including edits to wikis, attempts to exploit a public note-taking tool, and heavy automated traffic. Read the blog post on Diff for more details about the activity and the Foundation’s response.

Meetings and events

• Save the date for the next Wikimedia Hackathon! We’ll be meeting in lovely Tirana, Albania for the 2027 Wikimedia Hackathon from April 9–11, 2027. Scholarship and staff sponsorship applications are currently being accepted through Pretix and will close on October 30, 2026. General registration will open in January 2027.

Updates for editors

• To measure the impact of incorporating some community-requested features on logged-out reader retention, a test for Image Carousel will be pushed to logged-out readers. With the Image Carousel feature, readers browse community-uploaded images, selected by editors as relevant to specific articles. The test starts on November 20.
• An experimental notice will be pushed to 0.5% of logged-out mobile readers who come to English Wikipedia from Google, asking them to add Wikipedia as a Google Preferred Source. The test is to see if this notice increases reader retention and encourages people who use Google Search to visit Wikipedia more often. It will run from October 15–29 and will be assessed for its impact on retention and referrals.
• View all 26 community-submitted tasks that were resolved last week. For example, an issue where Quarry returned an “Access denied” error when users tried to run SQL queries, preventing queries from running normally, has now been fixed.

Updates for technical contributors

• Due to a long-standing bug, applications that use the OAuth 2 client credentials flow to act on their owners’ behalf are treated as if they are logged out. This will be fixed for new applications registered on or after Monday, October 19. Some affected applications need to re-register.
• Detailed code updates later this week: MediaWiki

Meetings and events

• A proposal to hold the Wikimedia Hackathon every three years, with regional hackathons in between, has been shared. It explores making the event more accessible to technical communities in different regions. Share your feedback on the proposal’s talk page before November 6.

Weekly highlight

• An experiment launched on September 29 is testing article recommendations for new account holders who also identify as readers. By suggesting articles to read, similar to recommendations in the Wikipedia app for logged-in readers, the experiment aims to encourage new account holders to read and return to the website regularly, with the goal of increasing internal referrals by 1%. See the related Community Wishlist proposal.
• Several Wikimedia services were taken offline last week because of a security vulnerability in PHP. This is because they need to be updated before they are safe to put back online. This is not a problem just for the Wikimedia movement but affects a lot of websites. You can follow updates on Wikitech. Cloud VPS and Toolforge will take longer to bring back online. This is to make sure that applications which run on Cloud VPS or Toolforge are not affected. Tool developers can see updates and more information on the Cloud-announce mailing list.
• Last week we shared that to measure the impact of incorporating some community-requested features on logged-out reader retention, a test for the Image Carousel feature would be pushed to logged-out readers. Due to an issue, we will be restarting the test, but it will be live on October 26, not November 20 as initially announced.

Updates for editors

• A new bot detection system to better identify automated traffic that disguises itself as human visitors, is coming to the Wikimedia wikis. This might cause sudden changes to visitor statistics starting from 26 October, going back to 20 June 2026.
• The Score extension which renders musical notation inside wiki pages, has been temporarily disabled on all wikis due to a security issue. Affected pages will display a notice instead of musical scores, but the underlying code remains intact. No action is needed from editors, and a fix is in progress. A separate announcement will follow when the extension is re-enabled. Read more on Phabricator.
• View all 18 community-submitted tasks that were resolved last week. For example, the issue where CodeMirror syntax highlighter appears to have been enabled in error for existing editors has been fixed.

Updates for technical contributors

• All wikis will be read-only for a few minutes on Wednesday, October 28 2026 at 15:00 UTC. This is for the datacenter server switchover backup tests, which happen twice a year. During the switchover, all Wikimedia website traffic is shifted from one primary data center to the backup data center to test availability and prevent service disruption even in emergencies.
