Fixes #4321

Summary by CodeRabbit

  • Release Improvements
    • Stable community and self-hosted server and runner images receive the latest tag only when their release is the highest applicable stable version. Prerelease community tags are excluded from the stable-version comparison.
    • Beta server and runner images retain their version-specific tags without receiving the latest tag.
    • Community and self-hosted release runs are serialized, and queued runs wait for an active release to finish rather than canceling it.

📝 Walkthrough

Walkthrough

Community and pro release workflows serialize runs and compare the triggering tag with the highest stable version tag. Server and runner image metadata use that result to set the latest flavor. The pro self-hosted beta workflow disables that flavor.

Changes

Release image tagging

Layer / File(s) Summary
Serialize release workflow runs
.github/workflows/community_release.yml, .github/workflows/pro_selfhosted_release.yml
Both workflows use concurrency groups, do not cancel in-progress runs, and allow queued runs up to the configured limit.
Set image latest flavors
.github/workflows/community_release.yml, .github/workflows/pro_selfhosted_release.yml, .github/workflows/pro_selfhosted_beta.yml
The community and pro release workflows compare the triggering tag with the highest stable version tag. Server and runner image metadata use the comparison result to set the latest flavor. The beta workflow disables the latest flavor for both images.

Review details

Before / after behavior

  • observed — Modified behavior in .github/workflows/pro_selfhosted_beta.yml: The Server metadata configuration now disables the latest flavor.
  • observed — Modified behavior in .github/workflows/pro_selfhosted_beta.yml: The Runner metadata configuration now disables the latest flavor.
  • observed — Modified behavior in .github/workflows/community_release.yml: Adds workflow-level concurrency using the community-release group, with in-progress runs not canceled and the queue set to max.
  • observed — Modified behavior in .github/workflows/community_release.yml: The deployment checkout now fetches full history. A new step compares the triggering tag with the highest stable vX.Y.Z tag and sets is_latest to true only on an exact match; prerelease tags are not included among candidate tags.

Review comments at @.github/workflows/community_release.yml:
- Around line 79-80: Prevent stale release runs from overwriting the latest
image: the pre-build tag check in both workflows is insufficient because an
older run may publish after a newer release. Add publication-time protection or
another mechanism that ensures only the current highest version can publish
latest. Update `.github/workflows/community_release.yml` lines 79-80 and
`.github/workflows/pro_selfhosted_release.yml` lines 93-94.
- Line 80: In .github/workflows/community_release.yml:80, pass github.ref_name
into the step through an environment variable and compare that variable with
HIGHEST_TAG instead of interpolating the ref directly into shell source. In
.github/workflows/pro_selfhosted_release.yml:94, no direct change is required;
its numeric-only tag pattern does not have this injection path.
