Hello, Everyone! A long time in the coming, Formtastic Bootstrap has just been pushed to RubyGems.
This is release provides all of the features of v1.0 but brings it forward to use Rails 3.2.x, Formtastic 2.2.x and Bootstrap 2.1.x.
There are a lot of neat Bootstrap features that have not yet been supported. I'm hoping these changes will come out of the community.
