Thanks for taking care of this @ParthivNaresh !

One thing I noticed is that I don't see the code changes for version 0.0.8 in the cmdstan-builder repository. The latest version is 0.0.4 from August. Can you push up the 0.0.8 version? It's probably a good idea to tag the release branches in github as well so we can keep track of the history better?

Also, should we just hardcode the cmdstan version installed via cmdstan-builder to 0.28.0 to avoid future breaking changes like this?
