Releases

Coop follows a lightweight release process so downstream users can depend on version tags (e.g. 1.0.1) instead of commit hashes. The process may evolve as project usage grows. There is currently no fixed release cadence; generally, releases are made when:

• Downstream users need an updated stable version tag,
• Meaningful changes have accumulated and CI is green, and/or
• A security advisory is addressed

We do not currently backport changes to or release patches for versions other than the latest.

Versioning

Coop uses Semantic Versioning (SemVer) following the MAJOR.MINOR.PATCH version format. In brief:

• Patch releases (x.y.Z): backward-compatible fixes or small improvements
• Minor releases (x.Y.z): new functionality or substantial improvements; changes to public API are backward-compatible
• Major releases (X.y.z): backward-incompatible changes to public API, or major feature or user interface overhauls

Creating a release

Before cutting a release, ensure:

• CI is passing for the main branch
• You understand the correct version according to SemVer
• CHANGELOG.md is up-to-date

Then:

1. In GitHub: Releases → Draft a new release
2. Create a tag in SemVer format x.y.z from the main branch
3. Draft the release notes, starting from CHANGELOG.md
4. Check Create a discussion for this release for at least major and minor releases
5. Publish the release

Publishing a release triggers automations:

• Docker images: builds and pushes version-tagged Docker images for coop-server, coop-worker, coop-client, and coop-migrations
• Docs: adds a folder for the release to the index with a snapshot of the docs
