- The `sdcard.transfer_port` variable is Marlin's internal serial port index, not the physical serial port number.
- Added packet number to "ok" response so hosts don't need to wait for the ACK.
- Renamed feature to `BINARY_FILE_TRANSFER`, as the speed up is only consequential to the ability to transfer binaries over serial.
Based on #10465
In response to `M115` the firmware reports if Thermal Protection is enabled (1) or not (0). This information can be used by software such as OctoPrint (more precisely the Printer Safety Check plugin) to warn users when Thermal Protection is not enabled in the firmware.
