有关改进:

现在AlarmClock可以直接播放警告音或震动，而过去必须通过AlarmManager才行，这里AlermManager开始播放通过一个IntentReceiver广播来实现，这些改变将会阻止从一个模态对话框中出现的警告。(AlarmClock alert now plays audio/vibe directly, rather than through AlarmManager. AlarmClock alert starts playing audio/vibe in its IntentReceiver, rather than on activity start. These changes should prevent alarms from being blocked by modal dialogs. )
修正设备休眠状态的稳定性问题
(Fixes to device sleep.)
在单独按下时不再打开拨号键盘，用户现在可以触摸或拖动它
(Single tap no longer opens the in-call dialpad; users now need to touch and drag it.)

(Fixes a bug causing approximately 1 in 25 outbound messages to freeze up the IMAP connection (to a Gmail based server) when transferred to the Sent folder. )

修正密码引用bug在IMAP协议中，以便用户能包含特定的字符在密码中比如空格键

保证自动检查邮件即使被标记为从不的帐户
