It would be more than a 'nice-to-have' if we could specifically select and label versions as a "Release". The current assumption is that selecting a specific revision is equivalent, but there are scenarios where it is necessary to keep release a build that spans "revisions" - especially when working on an incremental set of changes.
The only way I can see to do this right now is to restore all relevant versions individually and then use SQL Compare to manually revert those changes that have been committed in the "current" build but which wee do not want to release yet with those from earlier (released) version(s).
Ideally we would be able to tag individual commits with a build or release number and then retrieve using that number.
