请问哪里可以下载到2.5.0-dev7这个版本?
另，2.5.0-dev7是否是支持gae的版本中最新的版本?
非常感谢！

@life http://github.com/livid/v2ex zip就是
是否支持GAE最新版就得问 @livid 了。

@guokb 没有解决。在GAE里选择这次更新的版本号的话，依然如上报错。所以还是选回了旧版本。

@chouj 我是 2.4.0-RC1 升到 2.5.0-dev7 出跟似的（ t/50275 ），最後2行反的亦是：

raise BadValueError('Property %s is required' % self.name)
BadValueError: Property notification_position is required

然後，只是去了下 model.py ，topic.py ，notifications.py 三文件:

1. 在model.py中的第150-152行，有一段

raise datastore_errors.BadValueError(
"Property %s must be convertible to a %s instance (%s)" %
(self.name, self.data_type, value))

2. 在topic.py中有不少"notification"的句子，可以去搜下......

3. 在notifications.py中，有段是於notification_position的:

例如第55-57行

if self.member.notifications_position != n.num:
self.member.notifications_position = n.num
self.member.put()

第82-83行
if member.notifications_position is None:
member.notifications_position = 0

但是，我是代盲啊，不知道哪下手好，所以折不成功後也不了了之。

so , 是希望有熟悉babel且好心的童鞋能提供一助吧！！thx!
