+The default `shadow_normal_bias` value for `DirectionalLight` and `SpotLight` has changed to accommodate artifacts introduced with the new shadow PCF changes. It is unlikely (especially given the new PCF shadow behaviors with these values), but you might need to manually tweak this value if your scene requires a lower bias and it relied on the previous default value.
