Hi @moggsoceanlane ,
In short:
In Blender 4.0 and before there was Shade Auto Smooth in the Object (and Context) Menu; this could be adjusted in the Object Data Properties Panel.
In Blender 4.1, there was an ‘in-between’ situation, with two options, a Smooth By Angle in the Object Menu and also a Modifier Smooth By Angle.
Since Blender 4.2, there is only a Modifier: Smooth By Angle, but that can also be Added via the Object Menu, where it is now again called Shade Auto Smooth.
