This is much more useful than muting nodes (M) because you can be much more specific about what data is being passed through. You can now mute any node connection by dragging over it with Ctrl+Alt+RMB, similar to how Ctrl+RMB will cut the connection and Shift+RMB will combine and add reroutes. This will give you the full python path to the property as opposed to Copy Data Path which doesn’t include the object or material information. While not an aesthetic type UI change, a very helpful one is the new menu option, Copy Full Data Path, that you’ll find when you right-click on any property.

This means that you can quickly work between the two without Alt+Tab! On Windows, temporary windows like the render viewer or drivers editor are now drawn on top of the main window. The File Browser now supports the View Selected operator (hotkey number pad period), which will scroll to selected files. As always, be sure to reload factory settings when you update if you want to see the new defaults. But, I digress, this is a welcome improvement.

blend files would import hidden layers as disabled or hidden collections rather than being disabled from view with the monitor icon which is hidden by default. The Outliner now shows the camera icon for render visibility by default, which should reduce confusion for beginners.
