這次升級僅僅是一些安全修復，沒什麽大動作。
新手完全不用下載整個安裝包去覆蓋，
只要下載以下兩個文件，覆蓋原文件就OK。
第一個是修復安全問題的，必須要；
第二個是更改WordPress版本號的，可選~
原文如下：
A vulnerability in the Snoopy library was announced today. WordPress uses Snoopy to fetch the feeds shown in the Dashboard. Although this seems to be a low risk vulnerability for WordPress users, we wanted to get an update out immediately. 2.6.3 is available for download right now. If you don’t want to download the whole release to get the security fix, you can download the following two files and copy them over your 2.6.2 installation.
1. wp-includes/class-snoopy.php
2. wp-includes/version.php
