+- get version command to read the firmware version
+- get SHT heater measurement to read humidity and temperature measurement after heater activation. This command is available for firmware version >= 4.0.
+### Changed
+
+- Activate SHT heater duration reduced to 20ms. For firmware version >= 4.0 the get heater measurements command can be used to check if the heater has finished. With firmware versions < 4.0 one must wait at least 1300ms before issuing another command.
