Release procedure for Blubber

Before you start

The script installs the tools that it needs. You must have:

• The Go toolchain on your PATH.
• A signing key, for git tag --sign to work.
• Permission to push to the repository.

Run the release script

Run scripts/release.sh which will:

1. Increment the value in VERSION (minor by default; pass -p to do a patch release, or -M to do a major release).
2. Generate CHANGELOG.md using git chglog.
3. Show the changes and ask you to confirm them.
4. Update the image references in README.md to the new tag.
5. Commit VERSION, CHANGELOG.md, and README.md.
6. Create a signed version tag.
7. Open a merge request for the commit. The merge request merges when the pipeline succeeds.
8. Push the version tag after the merge request merges.
