 ## Next release (main branch)
 
+## v1.9.12
+
 - Fixed GL errors seen with MSAA on WebGL.
   Warning: this can affect multisampling behavior on devices that do not support OpenGL ES 3.1
 - Added new `getVertexIndex()` API for vertex shaders.
 
 ## v1.9.11
 
-- Added `sheenColor` and `sheenRoughness` properties to materials to create cloth/fabric
-- gltfio: added support for `KHR_materials_sheen`
-- gltfio: shader optimizations are now disabled by default, unless opting in or using ubershaders
-- Materials generation using `libfilamat` is now multi-threaded
+- Added support for Apple silicon Macs. build.sh can now be used to build on either Apple silicon or
+  Intel-based Macs. Pass the `-l` flag to build universal binaries.
+- Added `sheenColor` and `sheenRoughness` properties to materials to create cloth/fabric.
+- Materials generation using `libfilamat` is now multi-threaded.
 - `MaterialBuilder::build()` now expects a reference to a `JobSystem` to multi-thread shaders
   generation. A `JobSystem` can be obtained with `Engine::getJobSystem()` when using Filament,
-  or created directly otherwise (⚠️ **API change**)

+- WebGL: Include TypeScript bindings in releases.
+- engine: Fix, punctual lights get clipped at certain angles.
+- engine: Fix memory leak when calling `View::setViewport` frequently.
+- engine: Fix, materials not working on some Qualcomm devices.
+- engine: Modulate emissive by alpha on blended objects.
+- engine: Fix, RenderTarget cleared multiple times.
+- Java: Fix JNI bindings for color grading.
+- Android: reduced binary size.
