### For Maintainers: Release Process
To cut a minor version:
1. Create a new branch `release-<major>.<minor>` on top of the `main` commit you want to cut the version from and push it.
2. Create a new branch on top of the release branch, e.g. `<yourname>/cut-<major>.<minor>.<patch>`,
3. Change the `VERSION` file.
4. Update `CHANGELOG` (only user-impacting changes to mention).
5. Create PR, and get it reviewed.
6. Once merged, create a release with the `release-<major>.<minor>` tag on GitHub with the `<version> / <date>` title.
7. Announce on the prometheus-announce mailing list, slack and Twitter.
8. Merge the release branch back to the `main` using the "merge without squashing" approach (!).
> NOTE: In case of merge conflicts, you can checkout the release branch in a new branch, e.g. <yourname>/resolve-conflicts`, fix the merge problems there, and then do a PR into main from the new branch. In that way, you still get all the commits in the release branch back into `main`, but leave the release branch alone.
To cut the patch version:
1. Create a branch on top of the release branch you want to use.
2. Cherry-pick the fixes from the `main` branch (or add new commits) to fix critical bugs for that patch release.
3. Follow steps 3-8 as above.
