@@ -150,6 +150,10 @@ and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.
 - Fixed Render Graph Debug UI not refreshing correctly in the Render Pipeline Debugger.
 - Fixed SSS materials in planar reflections (case 1319027).
 - Fixed Decal's pivot edit mode 2D slider gizmo not supporting multi-edition
+- Fixed issue were the final image is inverted in the Y axis. Occurred only on final Player (non-dev for any platform) that use Dynamic Resolution Scaling with Contrast Adaptive Sharpening filter.
+- Fixed a bug with Reflection Probe baking would result in an incorrect baking reusing other's Reflection Probe baking
+- Fixed volumetric fog being visually chopped or missing when using hardware Dynamic Resolution Scaling.
+- Fixed generation of the packed depth pyramid when hardware Dynamic Resolution Scaling is enabled.
 
 ### Changed
 - Removed the material pass probe volumes evaluation mode.
