If you use it through git submodules , this is pretty easy.
$ cd libraries/lithium $ git log -1 | grep commit commit 97be2347d5a2e9b096db44c009df79ee9b6c0199
In this case, 0.10: https://github.com/UnionOfRAD/lithium/tags
I don't know if it makes sense to have strict version numbers in pre-1.0 state. Everything can and can break during the upgrade.
