    There’s plenty to get excited about
    here. A few of the headliner features
    are:

    • Brand new router with an emphasis on RESTful declarations
    • New Action Mailer API modelled after Action Controller (now without the agonizing pain of sending multipart messages!)
    • New Active Record chainable query language built on top of relational algebra
    • Unobtrusive JavaScript helpers with drivers for Prototype, jQuery, and more coming (end of inline JS)
    • Explicit dependency management with Bundler
