I was just wondering if a new C++ SDK will become available for the latest service release. Currently, the download from this page http://www.rhino3d.com/download/rhino-sdk/5.0/release gives me the 5.9 version.
Also, the link to the release notes on the download page has no destination (hasn’t had a destination for quite a while now) http://www.rhino3d.com/download/rhino-sdk/5.0/release/changes
