hub 2.2.0-preview1

This is the first preview release of the Go-powered hub. This marks a milestone where the rewrite of hub in Go that lived in jingweno/gh now became the main implementation.

Why Go? The problem with writing a command-line tool in Ruby is that it's very difficult to make it fast, and Ruby is required to be installed on the system for it to work. The Go executable is both fast and easy to install, since it bundles its own runtime.

The new implementation should be fully backwards compatible. Please file an issue if there's anything not working as expected.
