Hmm, looks like the toolbelt website (https://toolbelt.heroku.com/) is not for the latest toolbelt?!

I updated using gem update and got the latest 3.35.1.

But then when I updated heroku gem, I got the deprecation warning... ! The `heroku` gem has been deprecated and replaced with the Heroku Toolbelt. ! Download and install from: https://toolbelt.heroku.com ! For API access, see: https://github.com/heroku/heroku.rb
