Also update Underscore to 1.6. Includes the development versions of both, which are not included in the build. Here is Backbone's changelog: * Made the return values of Collection’s `set`, `add`, `remove`, and `reset` more useful. Instead of returning `this`, they now return the changed (added, removed or updated) model or list of models. (This means they can no longer be chained.) * Backbone Views no longer automatically attach options passed to the constructor as `this.options` and Backbone Models no longer attach `url` and `urlRoot` options, but you can do it yourself if you prefer. (But if you extend `wp.Backbone.View`, options will be attached for you.) * All `"invalid"` events now pass consistent arguments. First the model in question, then the error object, then options. * You are no longer permitted to change the id of your model during `parse`. Use `idAttribute` instead. * On the other hand, `parse` is now an excellent place to extract and vivify incoming nested JSON into associated submodels. See [27171] (next commit) for changes made to WordPress to be compatible with Backbone 1.1. props gcorne, georgestephanis. see #26799.
