The big item in this release is that the debug version of Rhino, both 32-bit and 64-bit, now work. In the Rhino 5 SR0 C++ SDK, the debug version of Rhino required a Beta license. This has been fixed, as the debug version of Rhino will just use your existing commercial or educational license.

Enjoy!
