only CB3 changes :

	Case fan control modified , the fan RPM has increased.
	Case fan rotation checking when switch on machine.
	The machine checks all fans automatically when short circuit detected on 12V line.	
	The user can disable the thermal prewarning message by M8020 S1/S0 code
	The user can disable the pre-calculation by M9090 S1/S0 code and the size parameters changeable too ( x y z maximums ).
	
Common changes:

	UNIX style linebreak handling improved
	Spanish language expanded.
	Redefined error message texts.
	The email type of messages is expanded ( pause in gcode , start print , stop print ). They can be turned on and off.
	The user can be turned on and off the Wifi module completely.
	Nozzle diameter settings. Extruder speed changes automatically by nozzle size settings under manual extrude.
	File parser changed. If the header contains some parameters of gcode the machine displays these and check the nozzle diameter too.

	Thermal runaway implemented:
		On/off-able by M1212 S1/S0 code. (defult On state)
		The default time is adjustable by Q(sec) parameter (default is 20 sec).
	
	The display shows some details when the user printing from an external host (like Octopi) if use these m-codes.
		M110 S1 - start code (initialize the printer and the display )
		M110 S2 - stop code (the printer steps into the default state)
	Octopi settings example:
		
		Before print job starts:
			T0 ; select head 1 
			M110 S1 ; initialize the printer and the display
			G28 ; Home all axes
		
		After print job completes:
			M110 S2 ; the printer steps into the default state
		
		After print job is cancelled:
			M110 S2  ; the printer steps into the default state
			M84  ; disable motors
			M104 S0 T0 ; switch off head 1 heating
			M104 S0 T1 ; switch off head 2 heating
			M140 S0 ; switch off bed heating
			M106 S0 ; disable object fan
		
		After print job is paused:
			G197 ; pause
			
		Before print job is resumed:
			G198 ; resume
	
		( install the progress bar code (M73) octopi plugin )
