### Release Version:

* 8064 - 9XTEND 115K HOPPING (DigiMesh)
* 28064 - 9XTEND 115K HOPPING (DigiMesh - Australia)

### Release Date:

* 2012-Jul-26

### New Features:

* In addition to DigiMesh packets, Directed Broadcast/Repeater and Point-Multipoint packets are now 
  supported. See the ATTO command or API TxOptions for more information.

* Holding the DIN line low on powerup will cause the module to automatically enter command mode.

* Added the ATBC (Byte Count) command.

* Added new DigiMesh diagnostics: Test Link, Trace Route, NACK, Aggregator and Node Replacement, 
  Find Neighbor, and Diagnostic Counts.

* Reformatted and re-ordered the .mxi file.

### Bug Fixes:

* RS-485 TX_EN (nCTS) is correctly set based on dev board dip switches allowing 485 four wire to 
  function.

### Known Issues / Errata:

* The ATAG command does not form complete routes for two way communications (like DigiMesh 
  unicasts). It does work well for one way communications to the originator of the ATAG broadcast 
  (for example, the command is very useful to form routes prior to sending a Network Discovery)

### Release Version:

* 8062 - 9XTEND 115K HOPPING (DigiMesh)
* 28062 - 9XTEND 115K HOPPING (DigiMesh - Australia)

### Release Date:

* 2011-Jun-07

### New Features:

* Now supports payload of 256 bytes.

* Added an API option to prevent route discoveries on a transmission attempt.
	* To disable route discoveries on a packet, set bit 1 (0x02) of the options byte of the TX_64 
	  (0x00) frame type. The options byte is the byte just before the data.

* Route request broadcasts are limited to the ATNH setting.

* MT option was added it is the number of repeated broadcasts in the mesh. The default of 3. 
  Previous versions used RR for broadcasts. Now RR only refers to the number of retries on a 
  unicast packet. 

* RR now defaults to 10.

* BH option was added for broadcast radius.

* CE was added defaults to 0. If set to 2 then the node won't route or echo broadcasts.

### Bug Fixes:

* CTS_EN is correctly set based on dev board dip switches allowing 485 four wire to function.

* Fixed ability to disable network ACKs through the API.

* Broadcast Radius (ATBH) is always limited to ATNH.

* RM command now does energy scans for a desired time interval. Before it ignored its parameter and 
  always did an instantaneous scan

* The api frame options byte bit 0 tells if a network ack was requested by the source node, and bit 
  1 tells if the destination address was the broadcast address. Before the options byte was a 
  constant 1 value.

### Known Issues / Errata:

* None
