Tech News: 2025-16

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

• 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. [2]
• 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. [3][4]

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. [5]
• "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.
• View all 30 community-submitted tasks that were resolved last week.

Updates for technical contributors

• The latest quarterly Technical Community Newsletter is now available. This edition includes: an invitation for tool maintainers to attend the Toolforge UI Community Feedback Session on April 15th; recent community metrics; and recent technical blog posts.
• Detailed code updates later this week: MediaWiki

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. [6]
• 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. [7]
• View all 37 community-submitted tasks that were resolved last week.

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.
