I've look. looked everywhere for the changes to the "New GSSL" PCB revision. Does anybody have the list of changes and or schematic?
 
yes, above link has it all, including new layout .pdf

only minor convenience changes (if it works, don't fix it )

In short:
- A bit of added psu filtering (2x 22 Ohm+1000uF)
- The new three-pin connector at TL074 to be shorted if no sidechain filter is used.
- 7812* and 22u* optional (for light+relay power)
- parts marked % omitted for pre-trimmed VCA
- 120K instead of 127K is updated value (but changes very little)
