Weekly highlight
- The Single User Login system is being updated over the next few months. This is the system which allows users to fill out the login form on one Wikimedia site and get logged in on all others at the same time. It needs to be updated because of the ways that browsers are increasingly restricting cross-___domain cookies. To accommodate these restrictions, login and account creation pages will move to a central ___domain, but it will still appear to the user as if they are on the originating wiki. The updated code will be enabled this week for users on test wikis. This change is planned to roll out to all users during February and March. See the SUL3 project page for more details and a timeline.
Updates for editors
- On wikis with PageAssessments installed, you can now filter search results to pages in a given WikiProject by using the
inproject:keyword. (These wikis: Arabic Wikipedia, English Wikipedia, English Wikivoyage, French Wikipedia, Hungarian Wikipedia, Nepali Wikipedia, Turkish Wikipedia, Chinese Wikipedia) [1] - One new wiki has been created: a Wikipedia in Tigre (
w:tig:) [2] 
View all 35 community-submitted tasks that were resolved last week. For example, there was a bug with updating a user's edit-count after making a rollback edit, which is now fixed. [3]
Updates for technical contributors
Wikimedia REST API users, such as bot operators and tool maintainers, may be affected by ongoing upgrades. Starting the week of January 13, we will begin rerouting some page content endpoints from RESTbase to the newer MediaWiki REST API endpoints for all wiki projects. This change was previously available on testwiki and should not affect existing functionality, but active users of the impacted endpoints may raise issues directly to the MediaWiki Interfaces Team in Phabricator if they arise.- Toolforge tool maintainers can now share their feedback on Toolforge UI, an initiative to provide a web platform that allows creating and managing Toolforge tools through a graphic interface, in addition to existing command-line workflows. This project aims to streamline active maintainers’ tasks, as well as make registration and deployment processes more accessible for new tool creators. The initiative is still at a very early stage, and the Cloud Services team is in the process of collecting feedback from the Toolforge community to help shape the solution to their needs. Read more and share your thoughts about Toolforge UI.
- For tool and library developers who use the OAuth system: The identity endpoint used for OAuth 1 and OAuth 2 returned a JSON object with an integer in its
subfield, which was incorrect (the field must always be a string). This has been fixed; the fix will be deployed to Wikimedia wikis on the week of January 13. [4] - Many wikis currently use Cite CSS to render custom footnote markers in Parsoid output. Starting January 20 these rules will be disabled, but the developers ask you to not clean up your MediaWiki:Common.css until February 20 to avoid issues during the migration. Your wikis might experience some small changes to footnote markers in Visual Editor and when using experimental Parsoid read mode, but if there are changes these are expected to bring the rendering in line with the legacy parser output. [5]
Meetings and events
- The next meeting in the series of Wikimedia Foundation Community Conversations with the Wikimedia Commons community will take place on January 15 at 8:00 UTC and at 16:00 UTC. The topic of this call is defining the priorities in tool investment for Commons. Contributors from all wikis, especially users who are maintaining tools for Commons, are welcome to attend.

Updates for editors
- Administrators can mass-delete multiple pages created by a user or IP address using Extension:Nuke. It previously only allowed deletion of pages created in the last 30 days. It can now delete pages from the last 90 days, provided it is targeting a specific user or IP address. [6]
- On wikis that use the Patrolled edits feature, when the rollback feature is used to revert an unpatrolled page revision, that revision will now be marked as "manually patrolled" instead of "autopatrolled", which is more accurate. Some editors that use filters on Recent Changes may need to update their filter settings. [7]
- View all 31 community-submitted tasks that were resolved last week. For example, the Visual Editor's "Insert link" feature did not always suggest existing pages properly when an editor started typing, which has now been fixed.
Updates for technical contributors
- The Structured Discussion extension (also known as Flow) is being progressively removed from the wikis. This extension is unmaintained and causes issues. It will be replaced by DiscussionTools, which is used on any regular talk page. The last group of wikis (Catalan Wikiquote, Wikimedia Finland, Goan Konkani Wikipedia, Kabyle Wikipedia, Portuguese Wikibooks, Wikimedia Sweden) will soon be contacted. If you have questions about this process, please ping Trizek (WMF) at your wiki. [8]
- The latest quarterly Technical Community Newsletter is now available. This edition includes: updates about services from the Data Platform Engineering teams, information about Codex from the Design System team, and more.

Weekly highlight
- Patrollers and admins - what information or context about edits or users could help you to make patroller or admin decisions more quickly or easily? The Wikimedia Foundation wants to hear from you to help guide its upcoming annual plan. Please consider sharing your thoughts on this and 13 other questions to shape the technical direction for next year.
Updates for editors
- iOS Wikipedia App users worldwide can now access a personalized Year in Review feature, which provides insights based on their reading and editing history on Wikipedia. This project is part of a broader effort to help welcome new readers as they discover and interact with encyclopedic content.
Edit patrollers now have a new feature available that can highlight potentially problematic new pages. When a page is created with the same title as a page which was previously deleted, a tag ('Recreated') will now be added, which users can filter for in Special:RecentChanges and Special:NewPages. [9]- Later this week, there will be a new warning for editors if they attempt to create a redirect that links to another redirect (a double redirect). The feature will recommend that they link directly to the second redirect's target page. Thanks to the user SomeRandomDeveloper for this improvement. [10]
- Wikimedia wikis allow WebAuthn-based second factor checks (such as hardware tokens) during login, but the feature is fragile and has very few users. The MediaWiki Platform team is temporarily disabling adding new WebAuthn keys, to avoid interfering with the rollout of SUL3 (single user login version 3). Existing keys are unaffected. [11]
- View all 30 community-submitted tasks that were resolved last week.
Updates for technical contributors
- For developers that use the MediaWiki History dumps: The Data Platform Engineering team has added a couple of new fields to these dumps, to support the Temporary Accounts initiative. If you maintain software that reads those dumps, please review your code and the updated documentation, since the order of the fields in the row will change. There will also be one field rename: in the
mediawiki_user_historydump, theanonymousfield will be renamed tois_anonymous. The changes will take effect with the next release of the dumps in February. [12]

Updates for editors
- Editors who use the "Special characters" editing-toolbar menu can now see the 32 special characters you have used most recently, across editing sessions on that wiki. This change should help make it easier to find the characters you use most often. The feature is in both the 2010 wikitext editor and VisualEditor. [13]
- Editors using the 2010 wikitext editor can now create sublists with correct indentation by selecting the line(s) you want to indent and then clicking the toolbar buttons.[14] You can now also insert
<code>tags using a new toolbar button.[15] Thanks to user stjn for these improvements. - Help is needed to ensure the citation generator works properly on each wiki.
- (1) Administrators should update the local versions of the page
MediaWiki:Citoid-template-type-map.jsonto include entries forpreprint,standard, anddataset; Here are example diffs to replicate for 'preprint' and for 'standard' and 'dataset'. - (2.1) If the citoid map in the citation template used for these types of references is missing, one will need to be added. (2.2) If the citoid map does exist, the TemplateData will need to be updated to include new field names. Here are example updates for 'preprint' and for 'standard' and 'dataset'. The new fields that may need to be supported are
archiveID,identifier,repository,organization,repositoryLocation,committee, andversionNumber. [16]
- (1) Administrators should update the local versions of the page
- One new wiki has been created: a Wikipedia in Central Kanuri (
w:knc:) [17] - View all 27 community-submitted tasks that were resolved last week. For example, the OCR (optical character recognition) tool used for Wikisource now supports a new language, Church Slavonic. [18]

Weekly highlight
- The Product and Technology Advisory Council (PTAC) has published a draft of their recommendations for the Wikimedia Foundation's Product and Technology department. They have recommended focusing on mobile experiences, particularly contributions. They request community feedback at the talk page by 21 February.
Updates for editors
- The "Special pages" portlet link will be moved from the "Toolbox" into the "Navigation" section of the main menu's sidebar by default. This change is because the Toolbox is intended for tools relating to the current page, not tools relating to the site, so the link will be more logically and consistently located. To modify this behavior and update CSS styling, administrators can follow the instructions at T385346. [19]
- As part of this year's work around improving the ways readers discover content on the wikis, the Web team will be running an experiment with a small number of readers that displays some suggestions for related or interesting articles within the search bar. Please check out the project page for more information.
- Template editors who use TemplateStyles can now customize output for users with specific accessibility needs by using accessibility related media queries (
prefers-reduced-motion,prefers-reduced-transparency,prefers-contrast, andforced-colors). Thanks to user Bawolff for these improvements. [20] - View all 22 community-submitted tasks that were resolved last week. For example, the global blocks log will now be shown directly on the Special:CentralAuth page, similarly to global locks, to simplify the workflows for stewards. [21]
Updates for technical contributors
- Wikidata now supports a special language as a "default for all languages" for labels and aliases. This is to avoid excessive duplication of the same information across many languages. If your Wikidata queries use labels, you may need to update them as some existing labels are getting removed. [22]
- The function
getDescriptionwas invoked on every Wiki page read and accounts for ~2.5% of a page's total load time. The calculated value will now be cached, reducing load on Wikimedia servers. [23] - As part of the RESTBase deprecation effort, the
/page/relatedendpoint has been blocked as of February 6, 2025, and will be removed soon. This timeline was chosen to align with the deprecation schedules for older Android and iOS versions. The stable alternative is the "morelike" action API in MediaWiki, and a migration example is available. The MediaWiki Interfaces team can be contacted for any questions. [24]
In depth
- The latest quarterly Language and Internationalization newsletter is available. It includes: Updates about the "Contribute" menu; details on some of the newest language editions of Wikipedia; details on new languages supported by the MediaWiki interface; updates on the Community-defined lists feature; and more.
- The latest Chart Project newsletter is available. It includes updates on the progress towards bringing better visibility into global charts usage and support for categorizing pages in the Data namespace on Commons.

Weekly highlight
- Communities using growth tools can now showcase one event on the
Special:Homepagefor newcomers. This feature will help newcomers to be informed about editing activities they can participate in. Administrators can create a new event to showcase atSpecial:CommunityConfiguration. To learn more about this feature, please read the Diff post, have a look at the documentation, or contact the Growth team.
Updates for editors
- Starting next week, talk pages at these wikis – Spanish Wikipedia, French Wikipedia, Italian Wikipedia, Japanese Wikipedia – will get a new design. This change was extensively tested as a Beta feature and is the last step of talk pages improvements. [25]
- You can now navigate to view a redirect page directly from its action pages, such as the history page. Previously, you were forced to first go to the redirect target. This change should help editors who work with redirects a lot. Thanks to user stjn for this improvement. [26]
- When a Cite reference is reused many times, wikis currently show either numbers like "1.23" or localized alphabetic markers like "a b c" in the reference list. Previously, if there were so many reuses that the alphabetic markers were all used, an error message was displayed. As part of the work to modernize Cite customization, these errors will no longer be shown and instead the backlinks will fall back to showing numeric markers like "1.23" once the alphabetic markers are all used.
- The log entries for each change to an editor's user-groups are now clearer by specifying exactly what has changed, instead of the plain before and after listings. Translators can help to update the localized versions. Thanks to user Msz2001 for these improvements.
- A new filter has been added to the Special:Nuke tool, which allows administrators to mass delete pages, to enable users to filter for pages in a range of page sizes (in bytes). This allows, for example, deleting pages only of a certain size or below. [27]
- Non-administrators can now check which pages are able to be deleted using the Special:Nuke tool. Thanks to user MolecularPilot for this and the previous improvements. [28]
- View all 25 community-submitted tasks that were resolved last week. For example, a bug was fixed in the configuration for the AV1 video file format, which enables these files to play again. [29]
Updates for technical contributors
- Parsoid Read Views is going to be rolling out to most Wiktionaries over the next few weeks, following the successful transition of Wikivoyage to Parsoid Read Views last year. For more information, see the Parsoid/Parser Unification project page. [30][31]
- Developers of tools that run on-wiki should note that
mw.Uriis deprecated. Tools requiringmw.Urimust explicitly declaremediawiki.Urias a ResourceLoader dependency, and should migrate to the browser nativeURLAPI soon. [32]

Updates for editors
- Administrators can now customize how the Babel feature creates categories using Special:CommunityConfiguration/Babel. They can rename language categories, choose whether they should be auto-created, and adjust other settings. [33]
- The wikimedia.org portal has been updated – and is receiving some ongoing improvements – to modernize and improve the accessibility of our portal pages. It now has better support for mobile layouts, updated wording and links, and better language support. Additionally, all of the Wikimedia project portals, such as wikibooks.org, now support dark mode when a reader is using that system setting. [34][35][36]
- One new wiki has been created: a Wiktionary in Santali (
wikt:sat:) [37] - View all 30 community-submitted tasks that were resolved last week. For example, a bug was fixed that prevented clicking on search results in the web-interface for some Firefox for Android phone configurations. [38]
Meetings and events
- The next Language Community Meeting is happening soon, February 28th at 14:00 UTC. This week's meeting will cover: highlights and technical updates on keyboard and tools for the Sámi languages, Translatewiki.net contributions from the Bahasa Lampung community in Indonesia, and technical Q&A. If you'd like to join, simply sign up on the wiki page.

Updates for editors
- All logged-in editors using the mobile view can now edit a full page. The "Edit full page" link is accessible from the "More" menu in the toolbar. This was previously only available to editors using the Advanced mobile contributions setting. [39]
- Interface administrators can now help to remove the deprecated Cite CSS code matching "
mw-ref" from their local MediaWiki:Common.css. The list of wikis in need of cleanup, and the code to remove, can be found with this global search and in this example, and you can learn more about how to help on the CSS migration project page. The Cite footnote markers ("[1]") are now rendered by Parsoid, and the deprecated CSS is no longer needed. The CSS for backlinks ("mw:referencedBy") should remain in place for now. This cleanup is expected to cause no visible changes for readers. Please help to remove this code before March 20, after which the development team will do it for you. - When editors embed a file (e.g.
[[File:MediaWiki.png]]) on a page that is protected with cascading protection, the software will no longer restrict edits to the file description page, only to new file uploads.[40] In contrast, transcluding a file description page (e.g.{{:File:MediaWiki.png}}) will now restrict edits to the page.[41] - When editors revert a file to an earlier version it will now require the same permissions as ordinarily uploading a new version of the file. The software now checks for 'reupload' or 'reupload-own' rights,[42] and respects cascading protection.[43]
- When administrators are listing pages for deletion with the Nuke tool, they can now also list associated talk pages and redirects for deletion, alongside pages created by the target, rather than needing to manually delete these pages afterwards. [44]
- The previously noted update to Single User Login, which will accommodate browser restrictions on cross-___domain cookies by moving login and account creation to a central ___domain, will now roll out to all users during March and April. The team plans to enable it for all new account creation on Group0 wikis this week. See the SUL3 project page for more details and an updated timeline.
- Since last week there has been a bug that shows some interface icons as black squares until the page has fully loaded. It will be fixed this week. [45]
- One new wiki has been created: a Wikipedia in Sylheti (
w:syl:) [46] - View all 23 community-submitted tasks that were resolved last week. For example, a bug was fixed with loading images in very old versions of the Firefox browser on mobile. [47]

Updates for editors
- Editors who use password managers at multiple wikis may notice changes in the future. The way that our wikis provide information to password managers about reusing passwords across domains has recently been updated, so some password managers might now offer you login credentials that you saved for a different Wikimedia site. Some password managers already did this, and are now doing it for more Wikimedia domains. This is part of the SUL3 project which aims to improve how our unified login works, and to keep it compatible with ongoing changes to the web-browsers we use. [48][49]
- The Wikipedia Apps Team is inviting interested users to help improve Wikipedia’s offline and limited internet use. After discussions in Afrika Baraza and the last ESEAP call, key challenges like search, editing, and offline access are being explored, with upcoming focus groups to dive deeper into these topics. All languages are welcome, and interpretation will be available. Want to share your thoughts? Join the discussion or email aramadan@wikimedia.org!
- All wikis will be read-only for a few minutes on March 19. This is planned at 14:00 UTC. More information will be published in Tech News and will also be posted on individual wikis in the coming weeks.

Weekly highlight
- Twice a year, around the equinoxes, the Wikimedia Foundation's Site Reliability Engineering (SRE) team performs a datacenter server switchover, redirecting all traffic from one primary server to its backup. This provides reliability in case of a crisis, as we can always fall back on the other datacenter. Thanks to the Listen to Wikipedia tool, you can hear the switchover take place: Before it begins, you'll hear the steady stream of edits; Then, as the system enters a brief read-only phase, the sound stops for a couple of minutes, before resuming after the switchover. You can read more about the background and details of this process on the Diff blog. If you want to keep an ear out for the next server switchover, listen to the wikis on March 19 at 14:00 UTC.
Updates for editors
- The improved Content Translation tool dashboard is now available in 10 Wikipedias and will be available for all Wikipedias soon. With the unified dashboard, desktop users can now: Translate new sections of an article; Discover and access topic-based article suggestion filters (initially available only for mobile device users); Discover and access the Community-defined lists filter, also known as "Collections", from wiki-projects and campaigns.
- On Wikimedia Commons, a new system to select the appropriate file categories has been introduced: if a category has one or more subcategories, users will be able to click on an arrow that will open the subcategories directly within the form, and choose the correct one. The parent category name will always be shown on top, and it will always be possible to come back to it. This should decrease the amount of work for volunteers in fixing/creating new categories. The change is also available on mobile. These changes are part of planned improvements to the UploadWizard.
- The Community Tech team is seeking wikis to join a pilot for the Multiblocks feature and a refreshed Special:Block page in late March. Multiblocks enables administrators to impose multiple different types of blocks on the same user at the same time. If you are an admin or steward and would like us to discuss joining the pilot with your community, please leave a message on the project talk page.
- Starting March 25, the Editing team will test a new feature for Edit Check at 12 Wikipedias: Multi-Check. Half of the newcomers on these wikis will see all Reference Checks during their edit session, while the other half will continue seeing only one. The goal of this test is to see if users are confused or discouraged when shown multiple Reference Checks (when relevant) within a single editing session. At these wikis, the tags used on edits that show References Check will be simplified, as multiple tags could be shown within a single edit. Changes to the tags are documented on Phabricator. [50]
- The Global reminder bot, which is a service for notifying users that their temporary user-rights are about to expire, now supports using the localized name of the user-rights group in the message heading. Translators can see the listing of existing translations and documentation to check if their language needs updating or creation.
- The GlobalPreferences gender setting, which is used for how the software should refer to you in interface messages, now works as expected by overriding the local defaults. [51]
- View all 26 community-submitted tasks that were resolved last week. For example, the Wikipedia App for Android had a bug fixed for when a user is browsing and searching in multiple languages. [52]
Updates for technical contributors
- Later this week, the way that Codex styles are loaded will be changing. There is a small risk that this may result in unstyled interface message boxes on certain pages. User generated content (e.g. templates) is not impacted. Gadgets may be impacted. If you see any issues please report them. See the linked task for details, screenshots, and documentation on how to fix any affected gadgets.

Weekly highlight
- The Wikimedia Foundation is seeking your feedback on the drafts of the objectives and key results that will shape the Foundation's Product and Technology priorities for the next fiscal year (starting in July). The objectives are broad high-level areas, and the key-results are measurable ways to track the success of their objectives. Please share your feedback on the talkpage, in any language, ideally before the end of April.
Updates for editors
- The CampaignEvents extension will be released to multiple wikis (see deployment plan for details) in April 2025, and the team has begun the process of engaging communities on the identified wikis. The extension provides tools to organize, manage, and promote collaborative activities (like events, edit-a-thons, and WikiProjects) on the wikis. The extension has three tools: Event Registration, Collaboration List, and Invitation Lists. It is currently on 13 Wikipedias, including English Wikipedia, French Wikipedia, and Spanish Wikipedia, as well as Wikidata. Questions or requests can be directed to the extension talk page or in Phabricator (with #campaigns-product-team tag).
- Starting the week of March 31st, wikis will be able to set which user groups can view private registrants in Event Registration, as part of the CampaignEvents extension. By default, event organizers and the local wiki admins will be able to see private registrants. This is a change from the current behavior, in which only event organizers can see private registrants. Wikis can change the default setup by requesting a configuration change in Phabricator (and adding the #campaigns-product-team tag). Participants of past events can cancel their registration at any time.
- Administrators at wikis that have a customized MediaWiki:Sidebar should check that it contains an entry for the Special pages listing. If it does not, they should add it using
* specialpages-url|specialpages. Wikis with a default sidebar will see the link moved from the page toolbox into the sidebar menu in April. [53] - The Minerva skin (mobile web) combines both Notice and Alert notifications within the bell icon (
). There was a long-standing bug where an indication for new notifications was only shown if you had unseen Alerts. This bug is now fixed. In the future, Minerva users will notice a counter atop the bell icon when you have 1 or more unseen Notices and/or Alerts. [54] - View all 23 community-submitted tasks that were resolved last week.
Updates for technical contributors
- VisualEditor has introduced a new client-side hook for developers to use when integrating with the VisualEditor target lifecycle. This hook should replace the existing lifecycle-related hooks, and be more consistent between different platforms. In addition, the new hook will apply to uses of VisualEditor outside of just full article editing, allowing gadgets to interact with the editor in DiscussionTools as well. The Editing Team intends to deprecate and eventually remove the old lifecycle hooks, so any use cases that this new hook does not cover would be of interest to them and can be shared in the task.
- Developers who use the
mw.ApiJavaScript library, can now identify the tool using it with theuserAgentparameter:var api = new mw.Api( { userAgent: 'GadgetNameHere/1.0.1' } );. If you maintain a gadget or user script, please set a user agent, because it helps with library and server maintenance and with differentiating between legitimate and illegitimate traffic.

Updates for editors
- The Editing team is working on a new Edit check: Peacock check. This check's goal is to identify non-neutral terms while a user is editing a wikipage, so that they can be informed that their edit should perhaps be changed before they publish it. This project is at the early stages, and the team is looking for communities' input: in this Phabricator task, they are gathering on-wiki policies, templates used to tag non-neutral articles, and the terms (jargon and keywords) used in edit summaries for the languages they are currently researching. You can participate by editing the table on Phabricator, commenting on the task, or directly messaging Trizek (WMF).
- Single User Login has now been updated on all wikis to move login and account creation to a central ___domain. This makes user login compatible with browser restrictions on cross-___domain cookies, which have prevented users of some browsers from staying logged in.

Updates for technical contributors
- Starting on March 31st, the MediaWiki Interfaces team will begin a limited release of generated OpenAPI specs and a SwaggerUI-based sandbox experience for MediaWiki REST APIs. They invite developers from a limited group of non-English Wikipedia communities (Arabic, German, French, Hebrew, Interlingua, Dutch, Chinese) to review the documentation and experiment with the sandbox in their preferred language. In addition to these specific Wikipedia projects, the sandbox and OpenAPI spec will be available on the on the test wiki REST Sandbox special page for developers with English as their preferred language. During the preview period, the MediaWiki Interfaces Team also invites developers to share feedback about your experience. The preview will last for approximately 2 weeks, after which the sandbox and OpenAPI specs will be made available across all wiki projects.

In depth
- Sometimes a small, one line code change can have great significance: in this case, it means that for the first time in years we're able to run all of the stack serving maps.wikimedia.org - a host dedicated to serving our wikis and their multi-lingual maps needs - from a single core datacenter, something we test every time we perform a datacenter switchover. This is important because it means that in case one of our datacenters is affected by a catastrophe, we'll still be able to serve the site. This change is the result of extensive work by two developers on porting the last component of the maps stack over to kubernetes, where we can allocate resources more efficiently than before, thus we're able to withstand more traffic in a single datacenter. This work involved a lot of complicated steps because this software, and the software libraries it uses, required many long overdue upgrades. This type of work makes the Wikimedia infrastructure more sustainable.
Meetings and events
- MediaWiki Users and Developers Workshop Spring 2025 is happening in Sandusky, USA, and online, from 14–16 May 2025. The workshop will feature discussions around the usage of MediaWiki software by and within companies in different industries and will inspire and onboard new users. Registration and presentation signup is now available at the workshop's website.

Weekly highlight
- Later this week, the default thumbnail size will be increased from 220px to 250px. This changes how pages are shown in all wikis and has been requested by some communities for many years, but wasn't previously possible due to technical limitations. [58]
- File thumbnails are now stored in discrete sizes. If a page specifies a thumbnail size that's not among the standard sizes (20, 40, 60, 120, 250, 330, 500, 960), then MediaWiki will pick the closest larger thumbnail size but will tell the browser to downscale it to the requested size. In these cases, nothing will change visually but users might load slightly larger images. If it doesn't matter which thumbnail size is used in a page, please pick one of the standard sizes to avoid the extra in-browser down-scaling step. [59][60]
Updates for editors
- The Wikimedia Foundation are working on a system called Edge Uniques which will enable A/B testing, help protect against Distributed denial-of-service attacks (DDoS attacks), and make it easier to understand how many visitors the Wikimedia sites have. This is so that they can more efficiently build tools which help readers, and make it easier for readers to find what they are looking for.
- To improve security for users, a small percentage of logins will now require that the account owner input a one-time password emailed to their account. It is recommended that you check that the email address on your account is set correctly, and that it has been confirmed, and that you have an email set for this purpose. [61]
- "Are you interested in taking a short survey to improve tools used for reviewing or reverting edits on your Wiki?" This question will be asked at 7 wikis starting next week, on Recent Changes and Watchlist pages. The Moderator Tools team wants to know more about activities that involve looking at new edits made to your Wikimedia project, and determining whether they adhere to your project's policies.
- On April 15, the full Wikidata graph will no longer be supported on query.wikidata.org. After this date, scholarly articles will be available through query-scholarly.wikidata.org, while the rest of the data hosted on Wikidata will be available through the query.wikidata.org endpoint. This is part of the scheduled split of the Wikidata Graph, which was announced in September 2024. More information is available on Wikidata.
- The latest quarterly Wikimedia Apps Newsletter is now available. It covers updates, experiments, and improvements made to the Wikipedia mobile apps.

Tech News: 2025-17
Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Updates for editors
- Wikifunctions is now integrated with Dagbani Wikipedia since April 15. It is the first project that will be able to call functions from Wikifunctions and integrate them in articles. A function is something that takes one or more inputs and transforms them into a desired output, such as adding up two numbers, converting miles into metres, calculating how much time has passed since an event, or declining a word into a case. Wikifunctions will allow users to do that through a simple call of a stable and global function, rather than via a local template. [62]
- A new type of lint error has been created: Empty headings (documentation). The Linter extension's purpose is to identify wikitext patterns that must or can be fixed in pages and provide some guidance about what the problems are with those patterns and how to fix them. [63]

Updates for technical contributors
- Following its publication on HuggingFace, the "Structured Contents" dataset, developed by Wikimedia Enterprise, is now also available on Kaggle. This Beta initiative is focused on making Wikimedia data more machine-readable for high-volume reusers. They are releasing this beta version in a ___location that open dataset communities already use, in order to seek feedback, to help improve the product for a future wider release. You can read more about the overall Structured Contents project, and about the first release that's freely usable.
- There is no new MediaWiki version this week.
Meetings and events
- The Editing and Machine Learning Teams invite interested volunteers to a video meeting to discuss Peacock check, which is the latest Edit check that will detect "peacock" or "overly-promotional" or "non-neutral" language whilst an editor is typing. Editors who work with newcomers, or help to fix this kind of writing, or are interested in how we use artificial intelligence in our projects are encouraged to attend. The meeting will be on April 28, 2025 at 18:00–19:00 UTC and hosted on Zoom.

Tech News: 2025-19
Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Weekly highlight
- The Wikimedia Foundation has shared the latest draft update to their annual plan for next year (July 2025–June 2026). This includes an executive summary (also on Diff), details about the three main goals (Infrastructure, Volunteer Support, and Effectiveness), global trends, and the budget and financial model. Feedback and questions are welcome on the talk page until the end of May.
Updates for editors
- For wikis that have the CampaignEvents extension enabled, two new feature improvements have been released:
- Admins can now choose which namespaces are permitted for Event Registration via Community Configuration (documentation). 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 the Collaboration List on a wiki page (documentation). The Collaboration List is an automated list of events and WikiProjects on the wikis, accessed via Special:AllEvents (example). 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.

Updates for technical contributors
- Developers who use the
momentlibrary in gadgets and user scripts should revise their code to use alternatives like theIntllibrary or the newmediawiki.DateFormatterlibrary. Themomentlibrary 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. - 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. [64] - Detailed code updates later this week: MediaWiki
In depth
- The latest Chart Project newsletter is available. 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.

This is to help more efficiently build tools which help readers, and make it easier for readers to find what they are looking for. Tech News has previously written about this. The deployment will be gradual. Some might see the Edge Uniques cookie the week of 19 May. You can discuss this on the talk page.
- Starting May 19, 2025, Event organisers in wikis with the CampaignEvents extension enabled can use Event Registration in the project namespace (e.g., Wikipedia namespace, Wikidata namespace). With this change, communities don't need admins to use the feature. However, wikis that don't want this change can remove and add the permitted namespaces at Special:CommunityConfiguration/CampaignEvents.
