 The shader function `SampleShadow_PCSS` now requires you to pass in an additional float2 parameter which contains the shadow atlas resolution in x and the inverse of the atlas resolution in y.
 
+## Shader config file
+
+From Unity 2020.2, due to the change of shadow map, the enum HDShadowFilteringQuality have been moved to HDShadowManager.cs and the variables ShaderConfig.s_DeferredShadowFiltering as well as the option ShaderOptions.DeferredShadowFiltering have been removed from the code as they have no impact anymore.

 ## Shader code
 
 From Unity 2020.2, HDRP uses a new structure to output information from the LightLoop. It now uses a custom LightLoop struct instead of the `float3 diffuseLighting`, `float3 specularLighting` pair. This is to allow HDRP to export more information from the LightLoop in the future without breaking the API.
