MovableBlog: MT 2.2 Released
June 26, 2002
New features: MySQL database support (don't worry if you don't have it or don't want to use it, you can still use the old file-based database system) and Trackback.
The most useful feature is MySQL support, since PHP has a MySQL interface, this means you can easily create dynamic content from the blog data without even relying on MT tags or any of the MT CGI scripts. The most interesting (and possibly revolutionary) feature, however, is Trackback, which enables a sort of conversation between MT-powered weblogs. While I believe there will be snags related to the conversion of MySQL will be difficult, the concept of Trackback will be the most difficult to explain (the logic of using it with bookmarklets is a little confusing for myself).
Also, the MT website has changed look to celebrate the new release.
