# 3.2.0

## Major updates
- Improved building process: We now run a full visual validation test for each pull request. Furthermore, code comments and what's new updates are now mandatory ([sebavan](https://github.com/sebavan))
- Introduced texture binding atlas. This optimization allows the engine to reuse texture bindings instead of rebinding textures when they are not on constant sampler indexes ([deltakosh](https://github.com/deltakosh))
- New [AnimationGroup class](http://doc.babylonjs.com/how_to/group) to control simultaneously multiple animations with different targets ([deltakosh](https://github.com/deltakosh))
- `WebVRCamera` now supports GearVR ([brianzinn](https://github.com/brianzinn))
- New glTF [serializer](https://github.com/BabylonJS/Babylon.js/tree/master/serializers/src/glTF/2.0). You can now export glTF or glb files directly from a Babylon scene ([kcoley](https://github.com/kcoley))

## Updates
- Tons of functions and classes received the code comments they deserved (All the community)

- Added GUI Textblock.lineSpacing setter and getter to configure vertical space between lines in pixels or percentage values when working with text wrapping ([carloslanderas](https://github.com/carloslanderas))

- VRHelper now has the public property teleportationEnabled to enable / disable camera teleportation. 
   ([carloslanderas](https://github.com/carloslanderas))

- Added documentation to WebVRCamera and VRExperienceHelper ([trevordev](https://github.com/trevordev))
- Introduced `isStroke` on `HighlightLayerOptions` which makes the highlight solid ([PixelsCommander](https://github.com/pixelscommander))
