This pull request does not seem to be a straightforward version bump. I'll have a human review this. If we don't respond within a day, feel free to ping us.

Why wasn't this detected as a plugin version bump:

file plugins/retina.yaml is not a straightforward version bump: version should have metadata ("rc2"), only no pre-release versions are auto-approved
/kind plugin-update
