featuring an entirely new UI based
on Twitter Bootstrap and other trappings of modernity!

Meanwhile, Casein 4...

Casein is an open-source CMS for Ruby on Rails, originally developed by Spoiled Milk.

It provides scaffolding generators and helper functions to quickly create a lightweight CRUD interface for your data, along with a pre-rolled user authentication system.

Casein is designed to be completely decoupled from the front-end. Therefore it may be added to new or existing Rails projects, or even used as a standalone CMS to drive platforms built on other technologies.

Now updated for Rails 4 and Ruby 2!
