Trial for WIP or Rhino 5 license

We have been using Rhino v5 since it came out. We are at the point of making a switch perhaps, but it would make more sense to switch to v7, rather than 6. We have some custom plug-ins for robotic welding that I’d want to test first.

Does this mean I have to wait until release and go with the trial? I can’t simply just use the rhino5 license? Or can an exception be made?

It means you’ll need to wait for V7 release, or upgrade to V6.
The WIP development cycle is open to people that own a permanent license of the current shipping version.
