The changelog has the full details blow-by-blow, but for those with a short attention span, here’s the big tickets:

• Dropped Rails 2 support
• Added Rails 3.1 support, including the asset pipeline
• Massive internal refactor, allowing for much simpler custom inputs
• Added many new classes to DOM elements to enable more efficient and descriptive CSS
• Massive refactor and simplification of the stylesheets
• Massive documentation effort
• Added support for HTML5 required, min, max, step, placeholder and autofocus attributes
• Improved support for Mongoid and MongoMapper documents
• Changed nested inputs() blocks to be automatically wrapped in an <li> tag to preserve HTML validity
• Changed quick forms to skip polymorphic associations (they didn’t work)
• Changed short hand forms to raise an error when trying to render an input for a polymorphic association (it didn’t work, need a collection)
• Changed input() to raise an error when a :collection is not provided for a polymorphic association (we can’t guess which class to use)
• Changed :label_method option to :member_label, :value_method option to :member_value, :grouped_label_method to :grouped_label (with backwards compat and deprecation warnings)

Enjoy!
