In KiCad 8, the integration between the schematic and PCB layout has been improved with the automatic reflection of net class assignments. Any net class assignments in the schematic are now seamlessly integrated into the PCB layout, visible in the 'PCBNew' environment.

The PCB layout will automatically reflect those changes when you create or modify net classes in the schematic. For example, if you have defined a net class for high-speed signals in the schematic, those signals will be grouped together, and the appropriate design rules will be applied to them in the PCB layout.

This new feature streamlines the design process and ensures that net classes are consistent between the schematic and layout, reducing the potential for errors and mismatches. It also saves time by manually eliminating the need to replicate net class assignments in the schematic and layout.
