MWF has began releasing release candidates for MediaWiki 1.40, and MediaWiki 1.40.0-rc.0 is the currently released version. The full launch is expected to come out sometime in June, and we can probably schedule an upgrade for around the end of July, providing that we fully test all of the extensions—this has already began testing with Miraheze, so we can likely pick up the slack given their crisis.

Extensions

CheckUser and CentralAuth have had some SQL patches that we need to be aware of. Below is a list of the patches we will need to run on migration.
