You now specify Node inputs via the Subgraph Input node and node outputs via the Subgraph Output node. Old subgraphs that used the old method will be automatically upgraded when deserializing  the graph. 

However it is preferred that you just upgrade all your subgraph nodes at once by accessing the ShaderGraphPlus Editor menu Upgrade Subgraph Projects.  It will deserialize and convert/upgrade and resave all of your subgraphs.

This window to upgrade wont last forever as the FunctionResult node & certain Parameter Node properties will be removed in a future update.

The Branch Node  is now depreciated and will show a warning when being used. It has been replaced by the Switch Node & Comparison Node

Added a new custom dock window that lets you view the generated code without having to open it up in a separate app in your os. No syntax highlighting yet.

Sampler states can now be set as an attribute and also have a few extra options to use which are also defined in the SamplerState struct defined in Sandbox.Rendering.

This update is something I've wanted todo for awhile and now that I've done it i think its time to start working on supporting custom lighting models 😀.
