火星了，今天才看到，wordpress 2.8.5 发布了。在wordpress 2.9之前的一个小小的升级版本，主要是：
* A fix for the Trackback Denial-of-Service attack that is currently being seen.
* Removal of areas within the code where php code in variables was evaluated.
* Switched the file upload functionality to be whitelisted for all users including Admins.
* Retiring of the two importers of Tag data from old plugins.
建议大家及时用wp后台自动升级。
