 Upgrade notes:
 - The compatible DuetWiFiServer version is 1.21. If you are already running firmware 1.19 or later, you can install this before or after upgrading the main firmware, it doesn't matter.
 - The compatible Duet Web Control is 1.21. Install it after upgrading the main firmware.
-- On Cartesian and CoreXY printers, normal G0 and G1 moves are no longer allowed before the corresponding axes have been homed. In particular, if your homex.g, homey.g and homeall.g files raise Z a little at the start and lower it at the end, you will need to add the S2 parameter to those G1 Z moves. Otherwise the G1 Z move will be refused unless Z has already been homed and the homing macro will be terminated.

 - The binary filename for the Duet WiFi and Duet Ethernet is now called Duet2CombinedFirmware.bin. However, your existing firmware version may expect it to be called DuetWiFiFirmware.bin or DuetEthernetFirmware.bin. For your convenience, this release includes copies of Duet2CombinedFirmware.bin with those names.
 - If you have a start.g macro file in the /sys folder of your SD card, remove or rename it, unless you want it to be run every time you start a print from SD card
