 - Added UV manipulation for Decals (edit mode).
 - Added color and intensity customization for Decals.
 - Added a history rejection criterion based on if the pixel was moving in world space (case 1302392).
+- Added an option to have double sided GI be controlled separately from material double-sided option.
 
 ### Fixed
+- Fixed an exception when opening the color picker in the material UI (case 1307143).
+- Fixed lights shadow frustum near and far planes.
+- Fixed various issues with non-temporal SSAO and rendergraph.
+- Fix screen being over-exposed when changing very different skies.
 
 ### Changed
 - Removed the material pass probe volumes evaluation mode.
 - Unifying the history validation pass so that it is only done once for the whole frame and not per effect.
+- Updated the tooltip for the Decal Angle Fade property (requires to enable Decal Layers in both HDRP asset and Frame settings) (case 1308048).
+- Fixed skybox for ortho cameras.

 | **BlendMask UV Mapping**                     | Use the drop-down to select the type of UV mapping that HDRP uses to map the **Layer Mask**.<br />&#8226; Unity manages four UV channels for a vertex: **UV0**, **UV1**, **UV2**, and **UV3**.<br />&#8226; **Planar:** A planar projection from top to bottom.<br />&#8226; **Triplanar**: A planar projection in three directions:X-axis: Left to rightY-axis: Top to bottomZ-axis: Front to back Unity blends these three projections together to produce the final result. |
 | **World Scale**                              | Set the world-space size of the Texture in meters. If you set this to **1**, then HDRP maps the Texture to 1 meter in world space.If you set this to **2**, then HDRP maps the Texture to 0.5 meters in world space.This property only appears when you select **Planar** or **Triplanar** from the **BlendMask UV Mapping** drop-down. |
 | **Tiling**                                   | Set an **X** and **Y** tile rate for the **Layer Mask** UV. HDRP uses the **X** and **Y** values to tile the Texture assigned to the **Layer Mask** across the Material’s surface, in object space. |

+<td>Determines how HDRP handles a material with regards to Double Sided GI. When selecting Auto, Double-Sided GI is enabled if the material is Double-Sided; otherwise selecting On or Off respectively enables or disables double sided GI regardless of the material's Double-Sided option.
+When enabled, the lightmapper accounts for both sides of the geometry when calculating Global Illumination. Backfaces are not rendered or added to lightmaps, but get treated as valid when seen from other objects. When using the Progressive Lightmapper backfaces bounce light using the same emission and albedo as frontfaces. (Currently this setting is only available when baking with the Progressive Lightmapper backend.).</td>
