OpenGL: Fixed ES 3.0 support on iOS.
OpenGL: Added support for KHR_debug in debug builds.
gltfio: Added Java / Kotlin bindings for Animator.
gltfio: Fixed panic with the Android gltf-bloom demo.
gltfio: Java clients should no longer call Filament#init.
Improved IBL diffuse by allowing to use the specular cubemap at roughness = 1 instead of Spherical Harmonics

v1.4.1

Added missing API documentation.
Fixed crash for sandboxed macOS apps using Filament.
Fixed an issue that limited the camera near plane to ~1mm.

Fix additional compatibility issues with MSVC, including the Vulkan backend.
matdbg: fixed missing symbol issue when linking against debug builds.
filamat: fixed crash when using the "lite" version of the library.
matinfo: Fix a crash with on Windows.
gltfio: fixed an animation loop bug.
gltfio: added support for sparse accessors.
Add JS binding to unary Camera::setExposure.

v1.4.0

API Breakage: Simplified public-facing Fence API.
Minimum API level on Android is now API 19 instead of API 21.
Filament can now be built with msvc 2019.
Added the ability to modify clip space coordinates in the vertex shader.
Added missing API documentation.
Improved existing API documentation.
Added Camera::setExposure(float) to directly control the camera's exposure.
Backface culling can now be toggled on material instances.
Face direction is now reversed when transforms have negative scale.
Dielectrics now behave properly under a white furnace (energy preserving and conserving).
Clear coat roughness now remains in the 0..1 (previously remapped to the 0..0.6 range).
gltfio: Fixed several limitations with ubershader mode.
gltfio: Fixed a transforms issue with non-uniform scale.
webgl: Fixed an issue with JPEG textures.
Windows: Fix link error in debug builds.
matdbg: Web server must now be enabled with an environment variable.
matdbg: Added support for editing GLSL and MSL code.

v1.3.2

Added optional web server for real-time inspection of shader code.
Added basic #include support in material files.
Fixed potential Metal memory leak.
Fixed intermittent memory overflow in wasm builds.
Fix bad normal mapping with skinning.
Java clients can now call getNativeObject().

v1.3.1

Unified Filament Sceneform and npm releases.
Improved cmgen SH with HDR images.
IndirectLight can now be queried for dominant direction and color.
Added support for vertex morphing.
Introduced custom attributes, accessible from the vertex shader.
Added Java / Kotlin bindings for KtxLoader.
Added JavaScript / Typescript bindings for the new RenderTarget class.
Added base path to glTF loadResources method for JavaScript.
Added support for iOS CVPixelBuffer external images with the OpenGL backend.

sceneform-1.9pr4

Added gltf_bloom Android sample to show gltfio and the RenderTarget API.
Added getMaterialInstanceAt to the Java version of RenderableManager.
Fix JNI bindings for setting values in parameter arrays.
Added JNI bindings for the gltfio library.
Fix support for parameter arrays in .mat files.
Added support for RGB_11_11_10
Removed support for RGBM (warning: source compatibility breakage)
IBL cubemap can now be of any size
Texture::generatePrefilterMipmap can be used for runtime generation of a reflection cubemap

sceneform-1.9pr3

Added Scene.addEntities() to the Java / Kotlin bindings.
Improved robustness in the tangents utility for meshes that have tangents and normals.
Introduced RenderTarget API that allows View to reference an offscreen render target.
Added lucy_bloom sample to demonstrate the new RenderTarget API.
Added Screen Space Ambient Occlusion support (SAO)
New blending modes: multiply and screen
Fixed an issue when sorting blended objects with different blending modes
The material property curvatureToRoughness has been replaced with specularAntiAliasing. This new specular anti-aliasing solution offers more control via two new properties: specularAntiAliasingVariance and specularAntiAliasingThreshold. They can also be set on material instances if needed
Added specular ambient occlusion to compute a new AO term applied to specular reflections (see specularAmbientOcclusion property in materials)
Added multi-bounce ambient occlusion to brighten AO and preserve local color (see multiBounceAmbientOcclusion property in materials)
Micro-shadowing is now applied to material ambient occlusion
Use a smaller 64x64 DFG LUT on mobile to reduce binary size
Added a distance field generator to libimage.
JavaScript MaterialInstance now supports vec4 colors.
Further reduced filamat binary size by removing reliance on stdlib.
Added a new, smaller, version of the filamat library, filamat_lite. Material optimization and compiling for non-OpenGL backends have been removed in favor of a smaller binary size.
Implemented hard fences for the Metal backend, enablying dynamic resolution support.
Improved SurfaceOrientation robustness when using UVs to generate tangents.
Created a RELEASE_NOTES.md file, to be updated with significant PRs.
