R1-1-8: 
•	Changes measurement system so that sensor input averaging of the sensor during a reading is now only one total measurement, this reduces the chance of SDI-12 sensors resetting values and recording that incorrect value, this was found predominantly with SDI-12 sensors that work on the principle of cumulative reading between measurements such as Rain Gauges.

R1-1-7:
•	Tweaks to the Watch Dog and Super Visor Timers to reduce the likelihood of measurements stopping due to “measurement initialization error” for when a measurement configuration with a large number of variables from sensors was exceeding the waiting time previously. 

R1-1-5:
•	Fixes issue relating to scheduler that caused missing data.

R1-1-1 to R1-1-4: 
•	Fixes possibility of SDI-12 bus power being stuck on when measurements are stopped, reducing the possibility of excess battery draw and battery low voltage failure.
•	Fixes warning glitch incorrectly reporting “Low Power” in datafile.
•	Fixes an issue where an update of channel configuration via Combined Instrument Software can cause SDI-12 bus power to turn on and remain on even after measurement is complete.


R1-1-0:
•	Improvements to SD Card power handling and external power supply handling.
•	Adds CRC feature and toggle option to SDI-12 Logger for improving data integrity verification.
•	Bug fix for an issue which was causing a file with corrupt information to be created when the instrument starts up with a low voltage external power supply.


R1-0-1:
•	Initial Release firmware for SDI-12 Logger
