Hello. I downloaded the plugin for 4.9 off of github, but when I try to compile it it says that I need at least Houdini 15.0. When I check the website, there's nothing anywhere about 15.0 or higher though for some reason.

Is there some hidden place somewhere where I can get 15.0? Or does it require some kind of license first? Is there an alpha/beta I need to sign up for?

Any help is appreciated.
