Something has changed recently on Heroku. I can't deploy my app as I've done before:
me@host my-project (master) $ git push staging master Counting objects: 52, done. Delta compression using up to 8 threads. Compressing objects: 100% (51/51), done.

I don't get it, i'm using
ruby 2.2.0 since the beginning:
me@host my-project (master) $ ruby -v ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14] me@host my-project (master) $ cat .ruby-version 2.2.0 me@host my-project (master) $ cat Gemfile | grep 'ruby' ruby '2.2.0'
I don't know how to tell bundler I'm still using ruby 2.2.0. My bundler have this in the bottom:
RUBY VERSION ruby 2.3.0p0 BUNDLED WITH 1.12.1
Why bundler doesn't use the ruby 2.2.0 version? It's using 2.3.0 instead...
