+`Sphere::intersects_obb` and `Frustum::intersects_obb` now take an `Affine3A` instead of a `Mat4`. You can use `Affine3A::from_mat4` or `Transform::compute_affine` to get an `Affine3A`.
+
+`MeshUniform` now stores its current and previous model transforms as 4x3 matrices. Helper functions were added to bevy_pbr::mesh_functions to unpack the data.
