Yes, a great deal has changed since its original release. In fact, that is one of the greatest things about MT. Trevor, the developer, is releasing new features and patches every week and actually listens to those that ask for features.

I can understand the resistance to change. It is a tough thing for many to do. I think once you try it out, you may be pleasantly surprised though. Also, I would download the latest development build as well just so you can see the changes that are taking place with it.
