• Change the name to CW40
• Add global backlight
• Add RGB underglow
• Add Alps compatibility

• Change the cystal package to HC49
• Change the mini USB package from SMD to TH

• I forget everything that I did, lots of little things
• fixed some unconnected pads (oops)
• cleaned up silkscreens again
• fixed diode pads to fit SOD-123 footprint
• fixed BOM info for components
• rounded PCB edges
• replaced slotted holes with... holes
• added Vcc and Gnd pins to LED expansion
• changed LED expansion pins to 2.54 pitch

• cleaned up silkscreens
• moved 'ROW5' expansion to GPIO7 (still ATMEGA32U4 pin8/PB0)
• added notes
• cleaned up and removed extra libs/mods

• pulled extra pin for ROW5 from ATMEGA pin 8/PB0
• changed drills for holes/slots to work with OSHpark
• added GPIO4, GPIO5, GPIO6 connectors to ATMEGA pins 26/PD6, 22/PD5, 11/PB3
• ran row and GPIO to 1.27mm headers on right-side of board for interconnect (ribbon cable spacing)

• added back missing slot on right side of board
• added LEDs for optional keys from v0.4
• generated pcb image * not sure why slots don't render properly
• removed bottom-of-board expansion pins

• added optional 1.25+1.0 and 1.0+1.25 for right-shift/fn keys

• based on the GH60 Rev B PCB
• SMT ATMEGA32U4 and other components on back of board
