Babylon.js/dist/preview release/what's new.md

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)
• 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)
• New AnimationGroup class to control simultaneously multiple animations with different targets (deltakosh)
• WebVRCamera now supports GearVR (brianzinn)
• New glTF serializer. You can now export glTF or glb files directly from a Babylon scene (kcoley)
• Babylon.js now uses Promises in addition to callbacks. We created several xxxAsync functions all over the framework (SceneLoader.AppendAsync for instance, which returns a Promise). A polyfill is also integrated to support older browsers (deltakosh)
• Introduced Projection Texture on SpotLight (spotLight.projectedLightTexture). (lostink)
