@wing328 I would suggest removing release.yml as it is not needed anymore.

Maybe it makes sense to have additional release job triggered manually? So it can handle version switching by parameters like we have before:

on:
  workflow_dispatch:
    inputs:
      releaseVersion:
        description: 'Release version to tag (e.g., 2.1.0). Will be used for release artifacts and git tag.'
        required: true
      developmentVersion:
        description: 'Next development version (e.g., 2.2.0-SNAPSHOT). Will be used for continuing development after release.'
        required: true

So on push to master snapshot version will be released automatically, but when we need to trigger release, it can be done manually. But this is up to you.

Thanks for the review. Do we still need the workflow to publish the image to docker hub? That's the reason why I keep it.

I see, we need for sure. Let's rename it then to "docker-release.yml" to make it clear. Feel free to merge. I will later think about a unified release job to invoke maven-release and docker-release at the same time. Just want to make it as simple as possible to perform the release with one click and not miss something.

FYI. Renamed to docker-release.yml via #817
