今天干脆把博客升级了一下，最新版——2.7。

备份、上传，一切顺利。但是，访问主域名时居然空白！再访问登录页面，发现有提示“数据库需要升级”——不会吧，难不成要升级租用服务器上的MySql？不管那么多了，不是有个“升级”按钮嘛，直接点击——呵呵，“数据库已经升级成功！”

噢，原来是wordpress的数据库结构有变化呀！虚惊一场。这下再访问主域名，OK。

试用了一下，感觉比原来的2.2版好用多了。 没看发版声明，就凭试用总结几点：

1. 与服务器交互更像是“桌面应用程序” 了，页面不必频繁刷新——用户体验不错。
2. 可以直接在发表文章时编辑“固定链接”——非常直观。
3. HTML源代码发表模式对标记的兼容性更好——更健壮了。
4. 其他……

顺便列几本wordpress图书吧。可惜的是，WordPress这么流行的CMS系统，国内居然没有引进、出版一本书。
