The PR title ("Correct auto tag functionality") doesn’t match the actual changes here (version/metadata bump + formatting). This makes the intent of the release harder to track in history and automation; please align the title and/or PR description to reflect the version sync + changelog addition (or add the missing functional changes if they were intended).
