[12.0.0] - 2021-01-11

Added

Added categories to the blackboard, enabling more control over the organization of shader properties and keywords in the Shader Graph tool. These categories are also reflected in the Material Inspector for URP + HDRP, for materials created from shader graphs.
Added ability to define custom vertex-to-fragment interpolators.
Support for the XboxSeries platform has been added.
Stereo Eye Index, Instance ID, and Vertex ID nodes added to the shadergraph library.
Added information about selecting and unselecting items to the Blackboard article.
Added View Vector Node documentation
Added custom interpolator thresholds on shadergraph project settings page.
Added custom interpolator documentation
Added subshadergraphs for SpeedTree 8 shadergraph support: SpeedTree8Wind, SpeedTree8ColorAlpha, SpeedTree8Billboard.
Added an HLSL file implementing a version of the Unity core LODDitheringTransition function which can be used in a Shader Graph
Added a new target for the built-in render pipeline, including Lit and Unlit sub-targets.
Added stage control to ShaderGraph Keywords, to allow fragment or vertex-only keywords.
For Texture2D properties, added linearGrey and red as options for default texture mode.
For Texture2D properties, changed the "bump" option to be called "Normal Map", and will now tag these properties with the [NormalMap] tag.
Added Branch On Input Connection node. This node can be used inside a subgraph to branch on the connection state of an exposed property.
Added Use Custom Binding option to properties. When this option is enabled, a property can be connected to a Branch On Input Connection node. The user provides a custom label that will be displayed on the exposed property, when it is disconnected in a graph.
Added new dropdown property type for subgraphs, to allow compile time branching that can be controlled from the parent graph, via the subgraph instance node.
Added Dropdown node per dropdown property, that can be used to configure the desired branch control.
Added selection highlight and picking shader passes for URP target.
Added the ability to mark textures / colors as [MainTexture] and [MainColor].
Added the ability to enable tiling and offset controls for a Texture2D input.
Added the Split Texture Transform node to allow using/overriding the provided tiling and offset from a texture input.
Added Calculate Level Of Detail Texture 2D node, for calculating a Texture2D LOD level.
Added Gather Texture 2D node, for retrieving the four samples (red component only) that would be used for bilinear interpolation when sampling a Texture2D.
Added toggle "Disable Global Mip Bias" in Sample Texture 2D and Sample Texture 2D array node. This checkbox disables the runtimes automatic Mip Bias, which for instance can be activated during dynamic resolution scaling.
Added Sprite option to Main Preview, which is similar to Quad but does not allow rotation. Sprite is used as the default preview for URP Sprite shaders.
Added Tessellation Option to PositionNode settings, to provide access to the pre-displaced tessellated position.
Added visible errors for invalid stage capability connections to shader graph.
Added a ShaderGraph animated preview framerate throttle.
Added many node synonyms for the Create Node search so that it's easier to find nodes.

[4.0.0-preview] - 2018-09-28

Added

Shader Graph now supports the High Definition Render Pipeline with both PBR and Unlit Master nodes. Shaders built with Shader Graph work with both the Lightweight and HD render pipelines.
You can now modify vertex position via the Position slot on the PBR and Unlit Master nodes. By default, the input to this node is object space position. Custom inputs to this slot should specify the absolute local position of a given vertex. Certain nodes (such as Procedural Shapes) are not viable in the vertex shader. Such nodes are incompatible with this slot.
You can now edit the Reference name for a property. To do so, select the property and type a new name next to Reference. If you want to reset to the default name, right-click Reference, and select Reset reference.
In the expanded property window, you can now toggle whether the property is exposed.
You can now change the path of Shader Graphs and Sub Graphs. When you change the path of a Shader Graph, this modifies the location it has in the shader selection list. When you change the path of Sub Graph, it will have a different location in the node creation menu.
Added Is Front Face node. With this node, you can change graph output depending on the face sign of a given fragment. If the current fragment is part of a front face, the node returns true. For a back face, the node returns false. Note: This functionality requires that you have enabled two sided on the Master node.
Gradient functionality is now available via two new nodes: Sample Gradient and Gradient Asset. 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.
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.
Added Sphere Mask node for which you can indicate the starting coordinate and center point. The sphere mask uses these with the Radius and Hardness parameters. Sphere mask functionality works in both 2D and 3D spaces, and is based on the vector coordinates in the Coords and Center input.
Added support for Texture 3D and Texture 2D Array via two new property types and four new nodes.
A new node Texture 2D LOD has been added 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.
Added Texel Size node, which allows you to 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.
Added Rotate About Axis node. This allows you to rotate a 3D vector space around an axis. For the rotation, you can specify an amount of degrees or a radian value.
Unpacking normal maps in object space.

Changed

The settings for master nodes now live in a small window that you can toggle on and off. Here, you can change various rendering settings for your shader.
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.
The Texture type default input now accepts render textures.
HD PBR subshader no longer duplicates surface description code into vertex shader.
If the current render pipeline is not compatible, master nodes now display an error badge.
The preview shader now only considers the current render pipeline. Because of this there is less code to compile, so the preview shader compiles faster.
When you rename a shader graph or sub shader graph locally on your disk, the title of the Shader Graph window, black board, and preview also updates.
Removed legacy matrices from Transfomation Matrix node.
Texture 2D Array and Texture 3D nodes can no longer be used in the vertex shader.

Normal Strength node now calculates Z value more accurately.
You can now connect Sub Graphs to vertex shader slots. If a node in the Sub Graph specifies a shader stage, that specific Sub Graph node is locked to that stage. When an instance of a Sub Graph node is connected to a slot that specifies a shader stage, all slots on that instance are locked to the stage.
Separated material options and tags.
Master node settings are now recreated when a topological modification occurs.

Fixed
