v1.5.3

• Plateau control system
• Telemetry

v1.5.2

• improve pressure control

v1.5.1

• calibrate pressure sensor's offset on startup
• better round displayed pressure values (in cmH2O)
• minor improvement to the pressure control

v1.5.0

• rework pressure and blower control
  (blower will now take more time to ramp up/down but this will greatly improve the stability of injected air volume in many scenario)
• rework alarms
  (better pressure alarms, better battery alarms, better snooze behavior)
• improve even more the measured and displayed pressures
  (if no plateau pressure if found, screen will now display a ? instead of an uncertain value)
• tweak the pressure control to make the plateau more accurate
• fix an issue with blower not restarting in some cases
• make sysclock more accurate
• improve code quality (MISRA)
• add a step in integration test to check O2 pipe

v1.3.2

• fix blower control
  (it used to unexpectedly slow down a bit from times to times)
• improve the measured and displayed pressures for peak and plateau

v1.3.1

• use the green LED near the start button to show whether the breathing mode is ON or not
• disable alarms related to the breathing cycle when program is stopped
• fix an issue with a battery alarm being briefly triggered at every boot
• integration test: open both valves at startup

v1.3.0

• add a program to test integration
• support electronic hardware v1 and v2
  (v1 by default, v2 through a config flag)
• implement start/stop
  (from now on, machine will begin stopped!)
• handle Emerson valves
  (through a config flag)
• improve the way buzzer is controlled

v1.2.3

• fix an issue with buzzer (sometimes it was stuck buzzing whereas no alarm were triggered)
• add battery-related alarms

v1.2.2
