• $on() now accepts regular Firebase events as an argument. In addition to "loaded" and "change", you may also subscribe for events like "value" and "child_added". (Full list of events available here).
• $set(), $save(), $add() and $remove() now all return promises. The promises will be resolved when the corresponding changes have been made on the server, or will be rejected with an appropriate error object.
• $auth() was added to objects returned by $firebase. This method is intended to be used for custom authentication. If you have custom generated tokens, pass them in to this function (it behaves identical to the Firebase.auth() method).
• The $firebaseAuth service was renamed to $firebaseSimpleLogin.
• $firebaseSimpleLogin no longer accepts a custom authentication token.
• The "anonymous" authentication provider has been added to $firebaseSimpleLogin.
• $changePassword(), $createUser(), and $removeUser() were added to the $firebaseSimpleLogin service. These behave identical to the corresponding Simple Login methods.
• Added $getCurrentUser() to the $firebaseSimpleLogin service. It returns a promise that will resolve to the user object when they log in.

• Overhauled the API to make it easier to understand and use in production Angular applications.
• The angularFire and angularFireCollection services are no longer available, and have been replaced by a single service named $firebase.
• The angularFireAuth service is now available as $firebaseAuth.
• The API for the $firebase service is significantly different than the old angularFire or angularFireCollection APIs.

• Fixed various bugs.

• Fixed various bugs.

• Improved underlying data merge behavior.
• The first argument to angularFire and angularFireCollection should be a Firebase reference, not a string. If you were passing a string URL, just call new Firebase(url) and pass that as reference instead.
• The fourth argument to angularFire is no longer required. The type of data will be automatically inferred from the local and remote data.
• angularFire returns a promise, but you no longer have to wait for the promise to resolve to modify the local models. Local and remote data will be merged when the remote data arrives.

A screencast, documentation and a quickstart guide was added to angularfire.com, the official site for the bindings here on out.

• Introduced support for Bower.
• Added the angularFireAuth service for easy user authentication.
• Added the ability to disassociate a binding to $scope.
• Fixed various bugs.

• Initial version of AngularFire which provides implicit and explicit synchronization primitives to associate Angular models and persist them with Firebase.
