Hello every body, When I want to upgrade from 1.4 to 2.0, I got a surprising refactoring, and I see class-name of some elements is changed (for example, they changed from sucess to btn-succes or actions to btn-actions, etc.), This question is about Css. Could any one please told me the reason of this changes?. What is benefits of using .btn-success vs .btn.success?
Thanks.
