Our npm package was last updated in April. Some of the changes since then:

⚠️ this version breaks compiled materials, use matc to recompile
⚠️ this version breaks IBL cubemaps, use cmgen to recreate them

Enhancements

Engine

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
Introduced RenderTarget API that allows View to reference an offscreen render target.
Added Screen Space Ambient Occlusion support (SAO)
Implemented hard fences for the Metal backend, enabling dynamic resolution support.
Stable mode for shadows
Improve shadows depth resolution for large scenes
Add support for polygon offset in shadow map parameters
Bake the constant bias into the shadow-map
Better clamping for dot(N, V) (#1106)
Decouple tone-mapping, FXAA, MSAA and dynamic resolution
MSAA is now disabled when post-processing is disabled

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
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
New blending modes: multiply and screen
Add postLightingColor property to materials (#1057)
Add new shading model to Filament for specularGlossiness. (#1083)
Allow dynamic two-sided lighting and materialThreshold

Added lucy_bloom desktop C++ sample to demonstrate the new RenderTarget API.
Added gltf_bloom Android Kotlin sample to show gltfio and the RenderTarget API.

Created a RELEASE_NOTES.md file, to be updated with significant PRs.
Fix support for parameter arrays in .mat files.
Added a distance field generator to libimage.
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.
Improved SurfaceOrientation robustness.
