-## [0.1.6] - 2018-xx-yy
-
-### New features and functionality
-- 
+## [2018.1.0f2]
-### Bug fixes
-- Fix fog flags in scene view is now taken into account
-- Fix sky in preview windows that were disappearing after a load of a new level
-- Fix numerical issues in IntersectRayAABB().
-- Fix alpha blending of volumetric lighting with transparent objects.
-- Fix the near plane of the V-Buffer causing out-of-bounds look-ups in the clustered data structure.
-- Depth and color pyramid are properly computed and sampled when the camera renders inside a viewport of a RTHandle.
+### Improvements
+- Screen Space Refraction projection model (Proxy raycasting, HiZ raymarching)
+- Screen Space Refraction settings as volume component
+- Added buffered frame history per camera
+- Port Global Density Volumes to the Interpolation Volume System.
+- Optimize ImportanceSampleLambert() to not require the tangent frame.
+- Generalize SampleVBuffer() to handle different sampling and reconstruction methods.
+- Improve the quality of volumetric lighting reprojection.
+- Optimize Morton Order code in the Subsurface Scattering pass.
+- Planar Reflection Probe support roughness (gaussian convolution of captured probe)
+- Only store decal textures to atlas if decal is visible, debounce out of memory decal atlas warning.
 
 ### Changed, Removals and deprecations
 - EnableShadowMask in FrameSettings (But shadowMaskSupport still disable by default)
 - Moved RTHandle static methods to RTHandles
 - Renamed RTHandle to RTHandleSystem.RTHandle
