0.54.2.3

Fixes

• CollectScenes : Fixed bug in set computations. This first appeared as a failure to display lights in the viewer in certain circumstances (#3497).

• Caching : Changed the cache used in various sub-systems to avoid potential compute failures (#3476).

• ShaderTweaks : Fixed missing preset for Arnold Blockers.
• Arnold : Fixed crash when disconnecting shader networks from lights (#3484).
• VectorDataWidget : Fixed styling update bug for non-editable widgets.
