### Release Version:

* 9007 (USA,MEX,CAN)

### Release Date:

* 2018-Jun-06

### New Features:

* Added support for secure remote AT commands. Note that **loading and running
  this code on a module will prevent the user from downgrading to a previous
  version of the software without support for secure remote AT commands.**


### Bug Fixes:

* Fixed a memory corruption issue caused by entering more than 64 characters
  on some commands in AT command mode.

### Known Issues / Errata:

* There is some bit jitter at low serial data rates (9600 baud and below) which
  may be incompatible with some host UARTs. If serial data loss is encountered,
  increasing the baud rate of the radio and host to 19200 baud or higher will
  provide a more stable interface.
* When the UART parity of the module is configured differently than the UART
  parity of the host, unpredictable output may occur on the serial port. This
  is easily resolved by setting the parity the same on the host and the module.

### Release Version:

* 9004 (USA,MEX,CAN)
* 9204 (AUS)
* 9304 (BRA)

### Release Date:

* 2017-Feb-14

### New Features:

* Added support for the RX LED on DIO12 (option 6)

### Bug Fixes:

* Resolved an issue where the CM (channel mask) was being reset to default when the module was reset rather than using the user saved value.

### Known Issues / Errata:

* There is some bit jitter at low serial data rates (9600 baud and below) which may be incompatible
  with some host UARTs. If serial data loss is encountered, increasing the baud rate of the radio
  and host to 19200 baud or higher will provide a more stable interface.
