R2-6-7:
•	Fixes a bug where logger will occasionally not complete the software shutdown sequence when external power is connected and subsequently removed.

R2-6-6:
•	New feature enabled that allows instruments to discharge from 4.20Volts to 4.00Volts and back up again as a cycle in response to having permanent external power detected via Bus Plugs or USB power for extended periods of time. This new discharge feature thus improves battery lifespan by allowing the battery voltage not to be constant 100% charged.
•	Onboard firmware improvements to the ADC measurement of charge state and to the power on and off state to improve stability when powering up and powering down the instrument. Improvements also improve Battery voltage and Internal Logger temperature measurement where previously they could “lock” or “freeze” at a given value and not recover until the instrument is rebooted.
•	Fixes bug where the ICT Device Firmware Updater program cannot update the application board for every different logger type resulting in the program reporting an error message, includes support for new revision FLASH memory chip to allow firmware updating to load correctly and then install
