ScriptableRenderPipeline/HDRenderPipeline/CHANGELOG.md

 - Enable texture streaming debugging (was not working before 2018.2)
 - Added Screen Space Reflection with Proxy Projection Model
 
+### Changed, Removals and deprecations
+- Removed GlobalLightLoopSettings.maxPlanarReflectionProbes and instead use value of GlobalLightLoopSettings.planarReflectionProbeCacheSize
+
 ## [2018.1 undecided]
 
 ### Improvements
+- Add 3D texture support for density volume
+- Add a better mapping of roughness to mipmap for planar reflection
 
 ### Changed, Removals and deprecations
 - Remove Resource folder of PreIntegratedFGD and add the resource to RenderPipeline Asset
 - Fix ConvertPhysicalLightIntensityToLightIntensity() function used when creating light from script to match HDLightEditor behavior
 - Fix numerical issues with the default value of mean free path of volumetric fog 
-- Fix the bug preventing decals from coexisting with density volumes 
+- Fix the bug preventing decals from coexisting with density volumes
+- Fix issue with alpha tested geometry using planar/triplanar mapping not render correctly or flickering (due to being wrongly alpha tested in depth prepass)
