      Alloy 1.6 will add support for Backbone 1.1.2. However, because of breaking changes in Backbone, 0.9.2 will remain the default for version the 1.6.0 release. (Future versions will make 1.1.2 the default, deprecate 0.9.2, and eventually remove support for 0.9.2.)

      A new config.json key has been added to specify that an app uses 1.1.2. Add

      "backbone": "1.1.2"

      Supported versions are 0.9.2 and 1.1.2.

      Due to breaking change in the Backbone library, existing apps may not run without modification. Backbone changes that must be accounted for:

      • Passing {silent:true} suppresses change:attr events entirely, thus a data-bound view will not be updated to reflect the changes. The sql sync adapter passed this option by default. It has been updated to no longer pass that option when Backbone 1.1.2 is used (still passed with 0.9.2). If you want the new behavior, you will need to pass this option with each fetch() or extend the collection.
      • Backbone collections no longer emit the 'reset' event after fetch, which means data-bound views will not update automatically after a fetch(). This could break existing apps. To use old functionality, pass {reset: true} when calling fetch() or extend the collection. The following sample code to extend the collection (commented out) has been added to the new-model template.

      // For Backbone v1.1.2, uncomment the following to override the
      // fetch method to account for a breaking change in Backbone.
      fetch: function(options) {
      	options = options ? _.clone(options) : {};
      	options.reset = true;
      	return Backbone.Collection.prototype.fetch.call(this, options);
