+- **$timeout/$interval:**

+Previously, even if invokeApply was set to false, a $rootScope digest would occur during promise
+resolution. This is no longer the case, as promises returned from $timeout and $interval will no
+longer trigger $evalAsync (which in turn causes a $digest) if `invokeApply` is false.
+
+Workarounds include manually triggering $scope.$apply(), or returning $q.defer().promise from a
+promise callback, and resolving or rejecting it when appropriate.

+    var interval = $interval(function() {
+      if (someRequirementFulfilled) {
+        $interval.cancel(interval);
+        $scope.$apply();
+      }
+    }, 100, 0, false);
+
+or:
+
+    var interval = $interval(function (idx) {
+      // make the magic happen
+    }, 1000, 10, false);
+    interval.then(function(idx) {
+      var deferred = $q.defer();
+      // do the asynchronous magic --- $evalAsync will cause a digest and cause
+      // bindings to update.
+      return deferred.promise;
