The latest updates to the mdlrelease tool allow the upgrade tool to determine the appropriate version for the release. However, we encountered some issues during the previous releases.

1. During the RC 2 release, the version bump incremented the .00 part of the version.php by 0.01 instead of using the release date.
2. While performing the {}type major{-} and -type back-to-dev releases, the processing for the version bump commit fails because the changes in version.php also get committed together with the Add upgrade notes commit.
3. While performing the --type rc 2, the Add upgrade notes commit also pumps the version.php using the release date. This causes an issue because the version bump commit will increase the version from .00 to .01 (HN)
