We recently released Pro Versioner 2.0.3, a minor update to our project backup and versioning tool.
Mountain Lion support
Pro Versioner now officially supports the recently released OS X 10.8 Mountain Lion.
Mass removal options
If you are running low on disk space and need to clear out some backups, the new Remove Backups options in the Edit menu can help.
You can choose to remove all backups, all except the x most recent, or all older than x days.
The full list of changes is here.
