升级到1.2之后，我的服务返回的promise具有不同的行为…
简单服务myDates：
简单服务myDates：
getDates: function () {
var deferred = $q.defer();
$http.get(aGoodURL).
success(function (data,status,headers,config) {
deferred.resolve(data); // we get to here fine.
})......
在早期版本中我只能做，在我的控制器：
$scope.theDates = myDates.getDates();
并且从getDates返回的promise可以直接绑定到Select元素。
现在这不工作，我被迫提供一个回调的promise在我的控制器或数据不绑定：
$scope.theDates = matchDates.getDates();
$scope.theDates.then(function (data) {
$scope.theDates = data; // this wasn't necessary in the past
文档仍然说：
$ q promises由模板引擎在角度中识别，这意味着在模板中，您可以将附加到作用域的promise视为结果值。
他们(承诺)在旧版本的Angular工作，但在1.2 RC3自动绑定失败在所有我简单的服务….任何想法，我可能会做错了。
1.2.0-rc3有一些变化，包括你提到的一个：

更改日志中有描述：
$parse:
@H_301_45@due to 07001,$parse and templates in general will no longer automatically unwrap promises. This feature has been deprecated and
if absolutely needed,it can be reenabled during transitional period
via$parseProvider.unwrapPromises(true)api.due to 07002,feature added in rc.2 that unwraps return values from functions if the values are promises (if promise unwrapping is enabled – see prevIoUs point),was reverted due to breaking a popular usage pattern.
