Yesterday, Movable Type announced the release of version 4.2 of Movable Type. The update adds threaded comments, built in support for TypePad AntiSpam, and redesigned template and widget management areas. The update adds the option to search assets, comments, TrackBacks, users, and custom data types or use another search backend. Like the most recent update of WordPress, templates can now be previewed live. The release also included general speed and security improvements.
