 - Fixed issue with automatic exposure settings not updating scene view.
 - Fixed issue with velocity rejection in post-DoF TAA. Fixing this reduces ghosting (case 1304381).
 - Fixed missing option to use POM on emissive for tessellated shaders.
+- Fixed an issue in the planar reflection probe convolution.
 
 ### Changed
 - Changed Window/Render Pipeline/HD Render Pipeline Wizard to Window/Rendering/HDRP Wizard
