Release Process

The Kargo Project is released on an as-needed basis. The process is as follows:

  1. An issue is proposing a new release with a changelog since the last release
  2. At least on of the OWNERS must LGTM this release
  3. An OWNER runs git tag -s $VERSION and inserts the changelog and pushes the tag with git push $VERSION
  4. The release issue is closed
  5. An announcement email is sent to kubernetes-dev@googlegroups.com with the subject [ANNOUNCE] kargo $VERSION is released

Major/minor releases, merge freezes and milestones

  • Kargo does not maintain stable branches for releases. Releases are tags, not branches, and there are no backports. Therefore, there is no need for merge freezes as well.

  • Fixes for major releases (vX.Y.0) are delivered via minor releases (vX.Y.Z) and assigned to the corresponding open milestone (vX.Y). That milestone remains open for the release support lifetime, which ends once the milestone closed. Then only a next major release can be done.

  • Kargo major releases are bound to the given kube_version and other components' versions, like etcd or network plugins. Older or newer versions are not supported and not tested for the given release.

  • Minor releases can change components' versions, but not the kube_version. Greater kube_version requires a new major release.
