刚刚才看到MovableType 4.2的rc3都已经发布了，马上就在MT4测试平台上做了更新。
提示升级，系统对数据库做了升级。
* Upgrading database from version 4.0063. * Upgrading table for MT::Entry::Meta records... * Upgrading table for MT::Asset::Meta records... * Upgrading table for MT::Author::Meta records... * Upgrading table for MT::TBPing::Meta records... * Upgrading table for MT::Category::Meta records... * Upgrading table for MT::Template::Meta records... * Upgrading table for MT::Blog::Meta records... * Upgrading table for MT::Comment::Meta records... * Recover permissions of system administrators... (100%) * Database has been upgraded to version 4.0066.
接着登入系统，做一个完整的重建动作，重建时出现下面的错误信息
An error occurred publishing entry 'Welcome Movable Type 4.2 release candidate': Publish error in template 'Entry': Error intag: error in module Comments: Publish error in template 'Comments': Error in tag: Error in tag: Error in tag: Unknown tag found: CommentReplyLink
估计是模板系统也有更新，所以把系统的模板refreshing，恢复到系统出厂设置，再次重建成功。Publish time: 28 seconds. 很快捷。
就是不知道何时正式版才会发布。
测试版下载地址在这里。
貌似只是
CommentReplyLink
改成了
CommentReplyToLink
我没有细看Tag的变化，反正我是打算等新版出来要重写模板了。现在用的模板是用了太久了。
