com.unity.render-pipelines.high-definition/CHANGELOG.md

 The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
 and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
 
+## [unreleased]
+
+
+### Added
+- Decal now support per channel selection mask. There is now two mode. One with BaseColor, Normal and Smoothness and another one more expensive with BaseColor, Normal, Smoothness, Metal and AO. Control is on HDRP Asset. This may require to launch an update script for old scene: 'Edit/Render Pipeline/Single step upgrade script/Upgrade all DecalMaterial MaskBlendMode'.
+
+### Fixed
+- Fixed an issue with PreIntegratedFGD texture being sometimes destroyed and not regenerated causing rendering to break
+- PostProcess input buffers are not copied anymore on PC if the viewport size matches the final render target size
+- Fixed an issue when manipulating a lot of decals, it was displaying a lot of errors in the inspector
+- Fixed capture material with reflection probe
+- Refactored Constant Buffers to avoid hitting the maximum number of bound CBs in some cases.
+- Fixed the light range affecting the transform scale when changed.
+
+### Changed
+- Movde Render Pipeline Debug "Windows from Windows->General-> Render Pipeline debug windows" to "Windows from Windows->Analysis-> Render Pipeline debug windows"
+
+### Added
+- Added support for RendererPriority on Renderer. This allow to control order of transparent rendering manually. HDRP have now two stage of sorting for transparent in addition to bact to front. Material have a priority then Renderer have a priority.
+- Add Coupling of (HD)Camera and HDAdditionalCameraData for reset and remove in inspector contextual menu of Camera
+- Add macro to forbid unity_ObjectToWorld/unity_WorldToObject to be use as it doesn't handle camera relative rendering

com.unity.shadergraph/CHANGELOG.md

 
 This adds gradient functionality via two new nodes. The Sample Gradient node samples a gradient given a Time parameter. You can define this gradient on the Gradient slot control view. The Gradient Asset node defines a gradient that can be sampled by multiple Sample Gradient nodes using different Time parameters.
 
+### Waveform nodes
+
+![](.data/wave_form_nodes.png)
+
+Math nodes now have a Waves category. The category has four different nodes: Triangle wave, Sawtooth wave, Square wave, and Noise Sine wave.
+The Triangle, Sawtooth, and Square wave nodes output a waveform with a range of -1 to 1 over a period of 1.
+The Noise Sine wave outputs a standard Sine wave with a range of -1 to 1 over a period of 2 * pi. For variance, random noise is added to the amplitude of the Sine wave, within a determined range.
+
+## Normal Derive Nodes
+
+![](.data/normal_derive_nodes.png)
+
+There are two Normal Derive Nodes: `Normal From Height` and `Normal Reconstruct Z`.
+`Normal From Height` uses Vector1 input to derive a normal map. `Normal Reconstruct Z` uses the X and Y components in Vector2 input to derive the proper Z value for a normal map. 
+
 ### Sphere Mask Node
 
 ![](.data/sphereMask.png)
 
 This adds a new node for LOD functionality on a Texture 2D Sample. Sample Texture 2D LOD uses the exact same input and output slots as Sample Texture 2D, but also includes an input for level of detail adjustments via a Vector1 slot. 
 
+### Texel Size Node
+
+![](.data/texel_size_node.png)
+
+With this node, you can get the special texture properties of a Texture 2D Asset via the `{texturename}_TexelSize` variable. Based on input from the Texture 2D Asset, the node outputs the width and height of the texel size in Vector1 format.
+
+**Note:** Do not use the default input to reference your texture Asset. It makes your graph perform worse. Connect this node to a separate Texture 2D Asset node per image example.
+
 ### Show generated code
 
 ![](.data/show_generated_code.gif)
 - Sub graphs are now suffixed with (sub), so you can tell them apart from other nodes.
 - Boolean and Texture type properties now function correctly in sub-graphs.
 - The preview of a node does not obstruct the selection outliner anymore.
+- The Texture type default input now accepts render textures.
 - The Dielectric Specular node no longer resets its control values.
 - HD PBR subshader no longer duplicates surface description code into vertex shader.
 - You can now copy, paste, and duplicate sub-graph nodes with vector type input ports.
+- The Lightweight PBR subshader now normalizes normal, tangent, and view direction correctly.
+- Texture 2D Array and Texture 3D nodes can no longer be used in the vertex shader.
+- Shader graphs using alpha clip now generate correct depth and shadow passes.
+- `Normal Create` node has been renamed to `Normal From Texture`.
