Release checklist

Pre-check:

• Make/ask to make a screenshot highlighting new features
  • Add a screenshot to the gallery and update it in the source tree
• There are no pending issues in the Roadmap for this release (if there are, move them away or close them)
• Check the correct branch/commit:
  • in the Quaternion repo
  • Quotient repo submodule ref
  • CI:
• Make sure the required version of libQuotient in CMakeLists.txt is up-to-date
• Pull translations
  • If needed, update the list of languages in CMakeLists.txt
  • Unset the branch tag after merging
• Check that contents of README.md, SECURITY.md, and BUILDING.md are up-to-date
• Rebuild and smoke-test the application
• If quaternion_en.ts is changed, review, commit and push the changes before proceeding

Actions:

• Go to the Releases page and make a new draft:
  • Set the tag (N.M.L, must not exist yet)
  • Describe all notable fixes/enhancements
  • Thank all contributors whose commits landed in this release
• Update the version number in main.cpp and CMakeLists.txt
• Add a release record to linux/io.github.quotient_im.Quaternion.appdata.xml
  • Copy a summary of changes from the draft at GH to the release <description>
• git commit
• git tag N.M.L && git push --follow-tags
• Update Flathub repo
  • Download and smoke-test the binary (check the version!); if something is off, delete the tag locally and on remotes, fix-commit-push, check that GitHub Actions are green, set again and push the same tag; a new Flathub build should start automatically
  • Merge the PR
• Refresh the page with the version release notes
  • Check that it shows "Existing tag" now
  • Publish
  • Update the Releases Wiki page
• Update the topic in #quaternion
• Post a TWIM update

Post-release:

• Open the release page in Incognito/Privacy mode; check:
  • the version
  • the Git tag
  • the screenshot
  • Check the pre-release checkbox if this version is a beta or release candidate
• Add '+git' to the version number in 'main.cpp'
• git commit && git push
