Updated the changelog with what is coming up for the next release.

CHANGELOG.md

 
 The property reference names are now editable. It is also now possible to make the properties not exposed.
 
+### Editable paths for graphs
+
+![](.data/change_path.gif)
+![](.data/use_path.gif)
+
+Enables the user to change the path of Shader Graphs and Sub Graphs. Changing the path of a Shader Graph modifies the location it has in the shader selection list. Likewise changing the path of Sub Graph modifies its location in the node creation menu.
+
+
+### 2 new Gradient nodes
+
+![](.data/gradient_node.png)
+
+This adds gradient functionality via two new nodes. Sample Gradient node, samples a gradient given a Time parameter. This gradient can be defined 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.

-- Pasting a property node into another graph will now convert it to a concrete node. ([#300](https://github.com/Unity-Technologies/ShaderGraph/issues/300))
+- Pasting a property node into another graph will now convert it to a concrete node. ([#300](https://github.com/Unity-Technologies/ShaderGraph/issues/300) and [#307](https://github.com/Unity-Technologies/ShaderGraph/pull/307))
+- Fixed an issue with editable sub graph paths, causing the search window to sometimes yield a null reference exception.
