• New observables for gamepads: onButtonDownObservable, onButtonUpObservable, onPadDownObservable, onPadUpObservable (deltakosh)
• New camera.storeState() and camera.restoreState() functions to store / restore cameras position / rotation / fov. Documentation (deltakosh)
• POW2 textures rescale is now done by shaders (It was previously done using canvas) (deltakosh)
• Added SceneLoader.CleanBoneMatrixWeights to force the loader to normalize matrix weights when loading bones (off by default) (deltakosh)
• Added camera.onViewMatrixChangedObservable and camera.onProjectionMatrixChangedObservable (deltakosh)
• Added support for folders when drag'n'dropping into the sandbox (deltakosh)
• Better serialization support (deltakosh)

• Improved the SPS perfs for dead or invisible solid particles (jerome)
• Added enableDepthSort parameter to the SPS in order to sort the particles from the camera position (jerome)
• Added pivot property to the SPS solid particles (jerome)
• Added the mesh facet depth sort to FacetData (jerome)

• Added AdvancedDynamicTexture.renderScale to allow users to render at higher DPI (deltakosh)
• WaterMaterial works on VR (RaananW)
• Playground has an optional createEngine function to replace the default engine. Example (RaananW)
• Error handling in the Assets Manager was revamped and now also includes a message and an exception (if provided). Documentation (RaananW)
