Issues 7 and 10 were closed in favor of this one. Is issue 7 slated to bring support to versions 9.X?

If so, are there any significant changes needed, or will simple version detection changes be sufficient?

I just pushed an update with the plumbing to change the version. To make sure it works, I'm going to march forward to add support for 9.0 through 9.3.

Awesome, this is one of my most used scripts for standing up new clusters.

Looking forward to 9.x versions. Need any reviewers?
