6.060 adds validation checks; basically checks your gdsa (teamdrive mounts) prior to deployment to warn you if you forgot to share the emails to you teamdrive or added to wrong teamdrive account.
6.060 released as another incase of any issues (works on extensive testing)
6.059 is released to fix a minor issue for 6.058.
In 6.058; if you generated a set of keys, regenerating new keys would be problematic. It would work the first time, but not the second time (even though it should have logically). 6.059 resolves that issue. So now you can redeploy keys over and over and not run into the issue.
Just note, you must share the generated email addresses. If you forget to this, your gdsa’s will show up blank!
