Wought, just got my kit today!
Noticed one interesting change that will make assembly a tad trickier, however...
The diodes should now mounted underside rather than topside, and a choice of SMDs and thru-hole diodes are provided; apparently this is due to inadequate room for thru-hole diodes topside between the mounting plate and PCB. I'm guessing there was a slight increase in the mounting plate thickness with whatever fab shop gave the lowest bid for plate cutting, and this meant that mounting the diodes topside wouldn't leave enough of the switch pins protruding through the PCB to solder to the underside.
It appears if we decided to use the thru-hole diodes provided instead of the SMDs, we would need to insert them from the underside and solder them same-side, rather than on the opposite side as usual. Fortunately, this would at least make it easier to clip the excess wire flush with the PCB on the topside, having no solder on that side bulking up the connection.
I'm thinking this may also make a case for getting switches with built-in diodes if available next time, as the board appears to be set up for that option already.
