Rhino 6 WIP Evaluation License

Hello everyone.
I have an evaluation license for Rhino 6, but I really want to try Rhino WIP so I can try its features. Rhino doesn’t allow me to download Rhino WIP using my Rhino 6 license.
Thank you help me to solve this.

The Work-In-Progress builds are only available to owners of the current shipping version.
When V6 was released, access to the new WIP that will produce V7, now requires a permanent V6 license.
