 - Introduced a new `IOfflineSupport` interface to hide IndexedDB ([Deltakosh](https://github.com/deltakosh))
 - `PBRMaterial` and `StandardMaterial` now use hot swapping feature for shaders. This means they can keep using a previous shader while a new one is being compiled ([Deltakosh](https://github.com/deltakosh))
 - Performance oriented changes ([barroij](https://github.com/barroij))
-  - prevent avoidable matrix inversion or square root computation.
-  - enable a removal in O(1) from the `transformNodes` array and `materials` array of the `Scene`. As a consequence, the order of the element within these arrays might change during a removal.
-  - enable a removal in O(1) from the `instances` array of a `Mesh`. As a consequence, the order of the element within this array might change during a removal.
-  - Stop calling `Array.splice` on the `scene.meshes` array and on the `engine._uniformBuffer` when removing an element. As a consequence, the order of the element within these arrays might change during a removal.

   - Added an option `useMaterialMeshMap` in the `Scene` constructor options. When set to true, each `Material` isntance will have and will keep up-to-date a map of its bound meshes. This is to avoid browsing all the meshes of the scene to retrieve the ones bound to the current material when disposing the Material. Disabled by default.
   - Added an option `useClonedMeshhMap` in the `Scene` constructor options. When set to true, each `Mesh` will have and will keep up-to-date a map of cloned meshes. This is to avoid browsing all the meshes of the scene to retrieve the ones that have the current mesh as source mesh. Disabled by default.
   - Added `blockfreeActiveMeshesAndRenderingGroups` property in the `Scene`, following the same model as `blockMaterialDirtyMechanism`. This is to avoid calling `Scene.freeActiveMeshes` and `Scene.freeRenderingGroups` for each disposed mesh when we dispose several meshes in a row. One have to set `blockfreeActiveMeshesAndRenderingGroups` to `true` just before disposing the meshes, and set it back to `false` just after.
-  - Prevent from doing useless and possible time consuming computation when disposing the `ShaderMaterial` of a `LinesMesh`.
+  - Prevented code from doing useless and possible time consuming computation when disposing the `ShaderMaterial` of a `LinesMesh`.
