New version of old PCB

We use this PCB since a few years. It's a low-noise power supply for audio equipment. Quite recently, we added some features which require some mods of the board. After applying the mods to the populated boards in stock, we decided to apply them to the PCB so that the subcontractor who populate the boards will apply the mods automatically. No pictures, sorry, as the boards are already at the subcontractor.
