今天看下后台，出现可升级选项，看下，竟然是wp系统升级，已经发布出来了3.0.1了，上次升级至3.0还是一个月之前。
备份也不想做了，按照上次的经验也没有做备份，并没有像他们那样进行手动备份，直接自动升级，应该出不了什么问题，出问题大不了在装一遍，呵呵。不到10s升级成功。
也没有出现什么不良反应，一切正常。有想试试的博主赶紧也开始升级吧，看看这次升级做了什么修改。

@劲博客
我的还好，他们改过程序的点升级就会很有问题了，我的只是表情没有备份，后面从以前备份的里面提出来覆盖下就好了，呵呵。
我点了升级，没有发生悲剧，也没有看出来有什么变化
@阿七
他们的改动了很多东西的吧，我这个小站基本上wp的东西没有动，所以直接升就还好，呵呵
阿邙升级后悲剧了
@灰太狼
呵呵，个人感觉没有什么区别的吧。
@P.H
呵呵 ，目前还没有怎么改动wp，就放心升了
@glwzu
没有改过wp的东西应该不会出什么问题的吧
@hesiway
表情忘了备份，待会找找以前的备份来换下。
不敢升，出问题就麻烦死了
默认表情~
