Firmware 1.17
-------------
Supports only Models AL834, ML912 & ML914

- (Bug fix) Fixed a bug with the AmpFlex/MiniFlex logger that causes improper measurements for storage intervals greater than five seconds when the gain is set on the high range.

Firmware 1.16
-------------
Supports all SLII Models except Models AL834, ML912 & ML914
NOTE: When upgrading to version 1.16 from 1.13 or lower it is necessary to perform a “Fail Safe” upgrade.

- (Bug fix) Fixed a bug which caused excessive power consumption.
- (Bug fix) Fixed a bug that would cause the Bluetooth module to turn on unexpectedly.
- (Bug fix) Fixed a bug that could leave the Memory LED on after an erase memory operation.
- (Change) Saved the On/Off state of the BT module (as last set by the user) into EEPROM. On reset/startup the On/Off state of the BT module is set based on this previously saved value.

Firmware 1.15
-------------

- (Change) Modified code to support turning the BT module on and off via the control button.
- (Bug fix) Fixed a bug in the boot loader code that prevented the logger from recovering gracefully from a reset.
- (Change) Removed code that would enable communications when a recording started. This would turn BT on for the BT models, even if it had been turned off by the user.
- (Change) Removed the communication count down that would prohibit the BT from being turned off for a period of time after communication ended. Now the user can turn off the BT immediately, even if it is communicating with the PC.
- (Change) Modified code to erase memory and not just set the index pointers when an erase memory command is given (via button control or remotely).
- (Bug fix) Fixed a bug in the L404 that would flash the memory LED much too slow when the erase command is originally given (via the control button).


Firmware 1.13
-------------
Without information.


Firmware 1.12
-------------

- (New features) New recording mode called  “Store on Alarm” to all models except the L404 event logger.
- (New features) Auto switch off after a non used period
- (bug fix) RTC access no longer lead to a firmware crash within the operating temperature range



Firmware 1.0
------------
Version initiale.
