Every Rhinoceros release from Rhino 2 (2001) to Rhino 8 (2023) — what it introduced, and how .3dm file compatibility works between them.
Rhino always opens files from older versions, and never from newer ones. Rhino 8 reads everything. Rhino 5 reads only Rhino 5 and older. If a file is too new, you need to convert it down.
The current release. Big changes to modeling history, meshing and materials.
The SubD release — Rhino finally gained true subdivision surface modeling.
Grasshopper became part of Rhino — a huge jump for parametric design.
First 64-bit release. Introduced Gumball and the modern surface toolset.
Improved rendering and workflow polish.
History recording arrived — construction geometry could stay live.
The first release built on the open-source OpenNURBS toolkit.
