This release has a completely reworked infrastructure. It allows for multiple distributions on the same cluster. It has yum based image build and package install, a smart package manager, a simple update path for master, clients, and images, a new package and database structure, new prerequisites handling, better pre-installation system configuration checking, a more flexible OS detection framework, modular distribution tarballs (smaller downloads), a newer systemimager with many new features, scalable Bittorrent deployment, a 2.6.18.1 deployment kernel, and UYOK (use your own kernel).
