As we kick of Helm 3 development, we want to make sure that (a) it is easy to do work on the Helm 3 codebase, and (b) we don't break the Helm experience for existing users.
After doing some investigation, we discovered that many people clone the `master` branch and expect a working Helm 2 instance, so for development on helm 3, we propose initially doing the development work on a separate branch, and then merging that branch to
master at `helm-3.0.0-beta.1` (a.k.a. The Distant Future).
So that leaves us with a name for the Helm 3 development branch. Our main two considerations for naming are (a) make it obvious, and (b) don't let it screw up SemVer-based clients like dep and glide.
