=================
Version 3.33.0 Feb 18, 2021

    Better handling for linear color space projects.
    Added TextureBlenderURP for the Universal Render Pipeline/Lit shader
    Improved collecting texture properties from result material. Was using the Material

    Bug Fix: NRE when trying to use listShadersInScene and with split into groups.
