     rendering and meshing thereby improving user experience.
   - Deprecate `SolidModels.MeshingParameters` in favour of new `mesh_scale`, `mesh_order`,
     `mesh_grading_default` accessed from `SolidModels`.
+  - Improvements to `SolidModels.render!` to improve stability and performance.
+    - Change `SolidModels.restrict_to_volume!` to perform a check if the simulation domain
+    already bounds all two and three dimensional objects, if so skips operation.
+    - Change `SolidModels.render!` to incorporate a two stage `_fragment_and_map!`
+    operation, reconciling vertices and segments before reconciling all entities. This
+    improves the robustness of the OpenCascade integration which can error in
+    synchronization if too much reconciliation is required all at once by `fragment`.
+    - These two operations in conjunction with the removal of `MeshSized` entities results
+      in a ~3x performance improvement in rendering the QPU17 example to `SolidModel`, and ~2x
+      improvement in total meshing time.
