This motivation will help creating new posts including new macros, toolbars and news.
Thank you all!
As mentioned here Rhino 6 WIP (work-in-progress phase) would be available to users who purchase Rhino 5 license. A recent search of mine turned with no results for downloading the WIP software. But a quick Google search leads us to this page where the change log of Rhino 6 WIP (10/21/2014) is announced. However, download button on the page redirects to the main download page of Rhino3D.com.
