Huh, I'm confused that this announcement doesn't even mention the existing `hub` tool, which is also in the `github` organization... this is a new rewrite replacement for it?

I agree the main thing I use `hub` for is PR management. Specifically creating PRs.

It had seemed to me that hub was somewhat undermaintained lately, so I guess I'm glad they've released a new tool which appears to maybe cover the same things, which perhaps will be better maintained.... but confused that they are releasing a new tool which does the same thing as an already existing tool also from github...
