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 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
• Create a PR with the following changes:
  • changes to env files
  • update commit hashes if needed
  • add release notes
• Test Release Candidate
  • CI should be green
  • run automated tests locally
  • deploy artifacts to test system and give the PM a heads up
• Prepare communication doc (folder) NOTE: add the changes we have made to the QuickStatements OAuth. Now it is fixed on the example directory: using a public url instead of a local one. There has been a change in the name of that variable as well.
