You'll have to reclone. Since the public repo is just recreated from the private one (where development happens), they do break history once in a while. :/

commit 7c5be74389aaf922af9f2be359d6ede6b67dedbd
Date: Thu Aug 6 10:02:23 2015 -0600
Update version to 12.2.1
```
As I said, however, the git-archive of that commit dow _not_ coincide with what Sandia distributes as their 12.2.1 tarball. For example, the git-archive [1] is 212 MB large, the official tarball [2] only 110 MB. This is because some testing files are removed from the tarball. Possibly there are other changes as well.
