The Wikimedia Hackathon 2022 will take place online on May 20–22. It will be in English. There are also local hackathon meetups in Germany, Ghana, Greece, India, Nigeria and the United States. Technically interested Wikimedians can work on software projects and learn new skills. You can also host a session or post a project you want to work on.
The new version of MediaWiki will be on test wikis and MediaWiki.org from 17 May. It will be on non-Wikipedia wikis and some Wikipedias from 18 May. It will be on all wikis from 19 May (calendar).
You can soon edit translatable pages in the visual editor. Translatable pages exist on for examples Meta and Commons.
