Release checklist

Step-by-step release process

Prepare release PR

• Create a branch named release-{version}:
  • If it's a patch release, based the new branch out of the one that
    contains the fixes. For example, if we added some fixes to the already
    released release-0.12 branch, then it will be the base for our 0.12.1
    release.
• Update Promscale in pkg/version/version.go update. If required, update
  the values for PrevReleaseVersion, PgVersionNumRange and
  ExtVersionRangeString.
  • Update EXTENSION_VERSION if there is a change in ExtVersionRangeString
• If the release includes changes to prom-migrator, update the version
  variable at migration-tool/cmd/prom-migrator/main.go.
• (optionally) Update prom-migrator version in .goreleaser.yml (2 places)
• Finalize CHANGELOG, adding release version and date
• Commit: git commit -a -m "Prepare for the 0.1.0-alpha.4 release"
• Create PR:
  • For major/minor releases the PR should target the master branch.
  • For patch releases the PR should target the release branch it was
    based of.
• Wait for review and merge.

Prepare git tag

• Pull the branch were the PR was merged, it should be master for
  major/minor and release-{version} for patch releases. Triple check that
  you have the right commit checked out.
• tag commit: git tag -a 0.1.0-alpha.1 -m "Release 0.1.0-alpha.1"
• push tag to main repo (not in fork!) git push origin 0.1.0-alpha.1

Create GitHub release notes

[ ] The goreleaser GitHub Action will automatically create a new draft release with the generated binaries, docker images, and a changelog attached. When it is created contact PM to validate if release notes are correct and click green publish button.

Post-release

For major/minor releases:

• Update Promscale and PrevReleaseVersion in pkg/version/version.go to the
  next devel version.
• If there is a hard dependency on promscale_extension version, make sure to modify pkg/tests/upgrade_tests/upgrade_test.go#getDBImages as done in this commit to return timescale image which has the required promscale_extension. Missing to do so will cause TestUpgradeFromPrev failure.
• Commit: git commit -a -m "Prepare for the next development cycle"
• Create PR & Merge when ready
• Update Promscale docs to point to the latest release as done in this PR

For patch releases:

• Update Promscale docs to point to the latest release as done in this
  PR.
• Create a branch based on master.
• Cherry-pick the commits related to the patch.
• Merge back into master.

Take a breath. You're done releasing.
