TAA and Physically based DoF

@@ -160,6 +160,7 @@ and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.
 - Added decal layer system similar to light layer. Mesh will receive a decal when both decal layer mask matches.
 - Added shader graph nodes for rendering a complex eye shader.
 - Added more controls to contact shadows and increased quality in some parts. 
+- Added a physically based option in DoF volume.
 
 ### Fixed
 - Fix when rescale probe all direction below zero (1219246)

 | **High Quality Filtering** | Enable the checkbox to make HDRP use bicubic filtering instead of bilinear filtering. This increases the resource intensity of the Depth Of Field effect, but results in smoother visuals.<br />This property only appears when you enable [more options](More-Options.html). |
+| **Physically Based** | Enable the checkbox to make HDRP use a more accurate but slower physically-based technique for the computation of Deph-of-Field. It is highly recommended to enable [Temporal anti-aliasing (TAA)](Anti-Aliasing) at the same time, for improved quality and performance.|
