Carrara 5 beta is available to all people who have upgraded from version 4. We are under no NDA as it is not the current beta that the official testers are using but it is an impressively stable version nonetheless. I'm not getting into all this crap throwing but suffice it to say that I have moved from Vue 5 / Infinite to Carrara 5 pro and am more than happy with my choice as it is right for MY toolkit and works as advertised.
