This release is a major milestone in the "Ultimate" series of distributions or distros for short; starting from this version forward upgrading from 1.4 to 1.5 etc. will be a click of the mouse away and without downloading 2GB every time. Full releases will still be available for download. This version you will find to be much faster & more responsive; due to the many enhancements to the kernel and being based on Ubuntu Feisty Fawn.
