至于2.0系列的我就不多说了，建议2.0的用户升级到2.1。

可以看得出来，从2.1.2到2.1.3的升级只需要把WordPress系统的根目录下的四个文件删除替换，并把wp-admin/和wp-includes/文件夹删除替换就可以了.当然还得废话一下，记得备份自己的数据和定制修改过的WordPress内容:)可以参考我以前写的相关文章。如果你使用SVN管理你的WordPress系统，升级更容易：

svn sw http://svn.automattic.com/wordpress/branches/2.1/ (注意：我升级2.1.2时官方还没tag到2.1.3)

WordPress愉快！
