Grasshopper, the world's most beautiful programming language, is now a full-fledged part of Rhino.
Presentation is key: With major changes to Rendering, Materials, or just plain capturing the viewport, it's now easier and faster to present, discuss, make decisions, and iterate.
Rhino's new display pipeline is faster, more stable, and uses features found on modern graphics hardware, like GPU sensitive shaders and memory optimizations.
Refined parts of the documentation workflow: from a completely reworked annotation-style interface, to better DWG support, and RichText throughout.
Make2D has been completely rewritten to provide faster, better, cleaner, more customizable results.
And much more...
