*Problems*

- MediaWiki 1.38-wmf.11 was scheduled to be deployed on some wikis last week. The deployment was delayed because of unexpected problems.

*Changes later this week*

- [image: Recurrent item] The new version https://www.mediawiki.org/wiki/MediaWiki_1.38/wmf.12 of MediaWiki will be on test wikis and MediaWiki.org from 7 December. It will be on non-Wikipedia wikis and some Wikipedias from 8 December. It will be on all wikis from 9 December (calendar https://www.mediawiki.org/wiki/MediaWiki_1.38/Roadmap). - At all Wikipedias, a Mentor Dashboard is now available at Special:MentorDashboard. It allows registered mentors, who take care of newcomers' first steps, to monitor their assigned newcomers' activity. It is part of the Growth features https://www.mediawiki.org/wiki/Special:MyLanguage/Growth/Feature_summary. You can learn more about activating the mentor list https://www.mediawiki.org/wiki/Special:MyLanguage/Growth/Communities/How_to_configure_the_mentors%27_list on your wiki and about the mentor dashboard project https://www.mediawiki.org/wiki/Special:MyLanguage/Growth/Mentor_dashboard . - [image: Advanced item] The predecessor to the current MediaWiki Action API https://www.mediawiki.org/wiki/API (which was created in 2008), action=ajax, will be removed this week. Any scripts or bots using it will need to switch to the corresponding API module. [1] https://phabricator.wikimedia.org/T42786 - [image: Advanced item] An old ResourceLoader module, jquery.jStorage, which was deprecated in 2016, will be removed this week. Any scripts or bots using it will need to switch to mediawiki.storage instead. [2] https://phabricator.wikimedia.org/T143034
