Here is a quick overview of highlights from the Wikimedia Foundation since our last issue on Feb 13. Please help translate.

Highlights

Birthday mode: This limited-time campaign feature celebrates 25 years of Wikipedia with a birthday mascot, Baby Globe. When turned on, Baby Globe is shown on ~2,500 articles, waiting to be discovered by readers. The feature is available for all Wikipedias to customise through Community Configuration until April 6. So far 17 Wikipedias have joined in the fun.
Wikipedia's 25th birthday party celebrated on Commons: Content from the January 15th global birthday party selected as Media of the day.

Etherpad cleanup: For security and performance reasons, all current pads on Wikimedia’s Etherpad instance, the web-based "ephemeral" editor for real-time collaborative document editing, will be permanently deleted after 30 April. We will continue running this Etherpad instance to support events and other short-term collaboration, but will be periodically deleting data going forward. If you have content in Etherpad you want to keep, please create local backups, as data will be permanently deleted and will not be able to be recovered.
Activity tab: Wikipedia iOS app has rolled out the improved Activity tab to all users in version 7.9.0. A/B test results showed increased account creation among users with access to the feature. Updates include enhanced editing impact insights, module customization, and relocation of History into the Search tab.
Reference Check: The feature Reference Check has been deployed to all Wikipedias. In A/B testing, the impact was substantial: newcomers shown Reference Check were approximately 2.2 times more likely to include a reference on desktop (or acknowledge/explain why they did not) and about 17.5 times more likely on mobile web.
Semantic search: The Foundation has launched a limited Android mobile app experiment that tests hybrid search capabilities which can handle both semantic and keyword queries. The Phase 1 beta is now live on Greek Wikipedia. The goal is to understand whether combining meaning-based retrieval with keyword search helps readers find information more effectively. Testing will expand to English, French, and Portuguese Wikipedias in March.
Navigation experience: The Foundation will run an experiment for mobile web users, that adds a table of contents and automatically expands all article sections, to learn more about navigation issues they face. The test will be available on Arabic, Chinese, English, French, Indonesian, and Vietnamese Wikipedias.

Site notices: Site notices (MediaWiki:Sitenotice and MediaWiki:Anonnotice) now will render on all platforms, not just on the desktop site. Users on mobile web will now see these notices and be informed.
Tech News: Latest updates from Tech News week 08 and 09 include the new “Edit full page” button for people who are editing a page-section using the mobile visual editor. They also link to the 40 community submitted tasks that were resolved over the last two weeks.
Wikifunctions: Abstract Wikipedia is going to have its public preview within the next few weeks, here is the preview.
