### Release Version:

* A005

### Release Date:

* 2017-June-6

### New Features:

* **PL** now supports 5 levels


### Bug Fixes:

* When streaming unicast data from radio to radio with mismatched UART baud
  rates, data was occasionally lost
* **DB** command did not always report accurate values
* **SS** was not updated on a module after it became the sleep coordinator
   with new **ST** and **SP** parameters.

### Known Issues / Errata:

* An extra network level retry sometimes occurs, causing TR and EA counts
  to be inflated on a failed unicast transmission.
* Synchronous sleep is unstable in a network with a mixture of SX and S8 modules.
  The S8 modules will go in and out of synchronization with the SX modules. If
  using synchronized sleep, it is recommended to not mix S8 and SX modules in
  the same network.
