Latest *tech news https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News* from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/2023/05 are available.

*Problems*

- Last week, for ~15 minutes, some users were unable to log in or edit pages. This was caused by a problem with session storage. [1] https://wikitech.wikimedia.org/wiki/Incidents/2023-01-24_sessionstore_quorum_issues

*Changes later this week*

- The new version https://www.mediawiki.org/wiki/MediaWiki_1.40/wmf.21 of MediaWiki will be on test wikis and MediaWiki.org from 31 January. It will be on non-Wikipedia wikis and some Wikipedias from 1 February. It will be on all wikis from 2 February (calendar https://www.mediawiki.org/wiki/MediaWiki_1.40/Roadmap).

*Future changes*

- Wikis that use localized numbering schemes for references need to add new CSS. This will help to show citation numbers the same way in all reading and editing modes. If your wiki would prefer to do it yourselves, please see the details and example CSS to copy from https://www.mediawiki.org/wiki/Special:MyLanguage/Parsoid/Parser_Unification/Cite_CSS, and also add your wiki to the list. Otherwise, the developers will directly help out starting the week of February 5.
