@dostovel I didn’t yet, so I asked professor Google:
View Layers
Render layers have been renamed to view layers, to indicate their expanded scope. Besides splitting up a render into multiple layers for compositing, they can now also be used as multiple views and variations of a scene for editing. Different windows can show different view layers, by selecting the scene and view layer in the top bar.
Collections can be excluded from specific view layers with the checkmark left of the name. They can also set to contribute only indirect light and shadows, or act as a holdout mask. These settings are edited in the outliner now.
