• Ember Simple Auth now supports FastBoot out-of-the-box (when using the cookie session store), see #1035.

• The cookie session store will now rewrite its cookies when any of its configurable properties (like cookie name) change, see #1056.
• The DataAdapterMixin now also overrides the headersForRequest method which makes it behave correctly with Ember Data 1.7 and above, see #1033.
• Configurable routes like the login route etc. are now configured via overriding properties of the respective route mixins instead of settings in config/environment.js, see #985.

• Authenticators can now reject with the server response when requests fail, see #1012.
• Server responses are now validated before authenticators resolve authentication, see #957.
• The offset that the OAuth 2.0 Password Grant authenticator uses when refreshing access tokens is now defined in an (overridable) property, see #840.
