本站用的就是古典 Blog 软件，MovableType。 升级之前是 8.0.4版本，最近 SixApart 发布了 MovableType 8.4.0， 8.0.5 等等。

今天找时间，升级了本站。

升级就是先做备份，备份了数据库，备份了整个网站。

然后从官方网站下载了最新的个人免费版本。

上传到服务器上，解压缩，然后覆盖原来的安装目录。

在自己的浏览器上，登录MovableType 后台，提示更新。

点击开始升级。

挺顺利。

然后我习惯是重建了网站，看看使用有没有问题。

也是顺利完成。

看来从 MovableType 8.0.4 到 8.4.0 算是一个大的版本升级。

列一下，主要的变化。

首先是 从8.0.4 到 8.4.0，中间包括了 8.1，8.2，8.3 的重大改变。
