已装完,平滑升级很爽,目前感觉改进最明显是Documentation 的 Search 不卡了,很爽

这次安装，和过去区别很大，不是下载一个installer，而是xcode.app本身，而且根目录下不会有Developer文件夹。只不过，很多原来带的组件，比如iOS Simulator，现在要额外下载了。

@yyfearth 都在Bundle里了,符合规矩么,自带5.0的Simulator,之前版本自己下

上个星期下载过4.2，这次有必要升级么？下载好慢好慢

Mac App Store 居然没提示要升级，只有直接下了 ……

大家小心安装4.3这个版本，安装之前一定不要直接删除4.2，要先看完readme，我之前装4.3 preview 3出现各种问题。
