-Trimesh is a pure Python (2.7-3.5+) library for loading and using [triangular meshes](https://en.wikipedia.org/wiki/Triangle_mesh) with an emphasis on watertight surfaces. The goal of the library is to provide a full featured and well tested Trimesh object which allows for easy manipulation and analysis, in the style of the Polygon object in the [Shapely library](https://github.com/Toblerity/Shapely).
+| :warning: WARNING          |
+|---------------------------|
+| `trimesh >= 4.0.0` on `main` makes minimum Python 3.7 and is in pre-release |
+| Testing with `pip install --pre trimesh` would be much appreciated! |
+| Projects that support Python<3.7 should update requirement to `trimesh<4` |

 The API is mostly stable, but this should not be relied on and is not guaranteed: install a specific version if you plan on deploying something using trimesh.
