Instrument firmware version	Features added
1.1	Setpoint “press-and-hold” loads current temperature to setpoint
1.2	Capacitance option card support added. Minor bug fixes.
1.3	Thermocouple revision 2 is now supported. Minor bug fixes.
1.4	Fixed bug that causes the thermocouple option to read incorrectly when a diode is attached to input B. Changed ramp rate limit to allow rates as low as 0.001 K/min.
1.5	Fixed bug where a sensor overload on a control input may not shut off the heater if the input is configured as a PTC sensor. Fixed bug where resetting default values may not correctly reset all settings. Fixed bug where resetting to defaults corrupts the first reading of KEYST?
