GraphEditor : Removed dynamic raster-space sizing of focus icon, as it caused excessive overlap with other nodes at certain zoom levels and on certain high resolution displays (#5435).
StringPlugValueWidget : Fixed bug handling Esc.
Arnold : Fixed unnecessary
opaqueattribute deprecation warnings. These are now only emitted in the case that
opaquehas been explicitly turned off.
ShaderUI : Fixed bug causing identical but independent shaders in a shader network from being included in the shader browser.
