The new upgrades are usually anounced at MTU.com, sometimes there is a thread posted here telling when they are released because of so many people asking when they would be released. As for what has changed in each upgrade, that changes with each upgrade, the newest and greatest is to be released Next week if all goes well 2.317, it will support the faster 48X plex that is on the market, and from the threads I have read, I think will support disc at once backups using two burners.
But the best place to find out about what is coming out, when, and what the changes are is to go to
www.mtu.com and click on NEWS in the right side...
