This release fixes bugs in the previous 3.6.x firmwares. See the change list at https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-363.
Also included in this release are:
- New firmware files for WiFi modules. See https://github.com/Duet3D/WiFiSocketServerRTOS/releases/tag/v2.3.0 for the change list.
- New bootloader files for tool and expansion boards. These bootloaders adapt automatically to CAN bit rates of 1Mbps, 500kbps and 250kbps.
- New IAP files (the file that needs to be on the SD card in order to install a main board firmware update). Although the files from previous releases will still work with this one, these new files will be required when upgrading to 3.7.x firmware.
