**Checklist:**
(another version of the checklist in T334778)
[] Do any other issues need to be specifically included in this release? if so, add them as children of this task
[] Review open backports for Wikimedia controlled Gerrit extensions included in the release, merging where appropriate [[ https://gerrit.wikimedia.org/r/q/status:open+branch:REL1_39(project:mediawiki/extensions/Babel+OR++project:mediawiki/extensions/cldr+OR++project:mediawiki/extensions/CirrusSearch+OR++project:mediawiki/extensions/ConfirmEdit+OR++project:mediawiki/extensions/Elastica+OR++project:mediawiki/extensions/EntitySchema+OR++project:mediawiki/extensions/Nuke+OR++project:mediawiki/extensions/OAuth+OR++project:mediawiki/extensions/Scribunto+OR++project:mediawiki/extensions/SyntaxHighlight_GeSHi+OR++project:mediawiki/extensions/UniversalLanguageSelector+OR++project:mediawiki/extensions/VisualEditor++project:mediawiki/extensions/WikibaseCirrusSearch+OR++project:mediawiki/extensions/WikibaseManifest) | link ]] (check that all extensions are included in the search and the correct REL_x version is used)
- It could be that trivial fixes are queued up ready in release branches. These can be merged ahead of a release so they are included in the release.
- To streamline the process in the future we may choose to drop this step
