My repo is the authoritative source of berrybrew now. The dnmfarrell repo was the original. It only gets updated after a major version bump.
v1.30 is the official currently released version. I'm currently working on v1.31 which is near-release. It's a release that will have no major functionality added, it's a release for me to get much better testing in place, and I've added the full ability for the return of return codes (per a request).
In both versions, there are slight UI issues that can arise, but they will be fixed before 1.31 is put out. The UI was just a simple idea I had, and wasn't meant to be even created, but as I got going, I liked it, and it stayed.
