| # This workflow runs after a merge to any release branch of the action. It: | |
| # 1. Tags the merge commit on the release branch that represents the new release with n `vN.x.y` | |
| # tag | |
| # 2. Updates the `vN` tag to refer to this merge commit. | |
| # 3. Iff vN == vLatest, merges any changes from the release back into the main branch. | |
| # Typically, this is just a single commit that updates the changelog. | |
