Welcome to Serengeti

Serengeti, named after the largest African Savanna, is where Rhino grows.

We like to involve users in every phase of the Rhino development process. As with prior releases, we invite current users to try, test, and provide feedback on the next release while still in development.

But now we have something new. You will now be able to participate in the development beyond the upcoming release.

Since many development efforts span more than one release, we have set up the Serengeti Project to give users more direct influence on all future Rhino developments.

This means you can always have access to the weekly builds of everything we are working on, no matter when or if it will be released. You will also have access to our internal developer discussion, developer notes, and issues tracking system.

We look forward to your input on future releases of Rhino and the Serengeti Project infrastructure.

The Rhino development team will post here as they work on Rhino.

System Requirements Please review before downloading.

Rhino 8 WIP is now available. Details and download…

More details:

  • CAUTION: These are weekly WIP builds. Often they are not stable or production-ready.
  • Do NOT uninstall your Rhino 7.
  • The Rhino 8 file format could change. To be safe, often Save As Rhino 7.
  • All Rhino 7 plugins might work with Rhino 8; let us know if they don’t.
  • Existing Grasshopper definitions should work with Rhino 8. Let us know if they don’t.

Have fun!
