After several years of unstable builds with our current JavaScript classes and functionality, the amazing Mootools team has released the latest version, 1.3 which includes great backwards-compatibility with all of our scripts: old and new.
All of the functionality added recently including the TimezonePicker, newest Uploader, and several others heavily depend on the newest builds of Mootools in order to function at top speed and reliability. Though long overdue, this update will provide an excellent boost in all areas possible to JavaScript-related functionality.
