================================================================================
Release Date: Aug. 25, 2009
Release Version: 8x44

+--------------+
| New Features |
+--------------+
 - Added a recovery mode for mains powered nodes in a sleeping router network which are reset.
   A coordinator will now repeatedly send a sync message when it first powers on.  When it 
   hears the sync echoed by a neighbor then it commences its normal cycle.  Changes to how
   the nomination process was implemented allows an existing network to detect and 
   override a newly powered on coordinator.

 - Added a sleep option which disables the coordinator from repeatedly sending a sync message
   during deployment.

 - Revised the sync structure (breaking compatibility with previous versions) to better support
   future compatibility.

 - Sleeping Router polls are now sent in the transmit state rather than in the holdoff 
   state to make use of the randomization provided by the holdoff state.

 - Added a new sleep status bit indicating when the node is in deployment mode.

 - To increase the chances of a node receiving a sync, the originator will
   listen for a sync after sending the first one.  If a sync relay doesn't happen,
   another one will be sent.

 - Added a new sleep option bit.  When this bit is enabled the election process
   does NOT take into consideration the node type (SM7 or SM8).

 - Added ability to disable route discoveries through the API.  This is done by
   setting option bit 1 (0x02).

 - Added the MS command (cycles without synch)

 - Added the ATSS (Sleep Status) command.

| Bug Fixes |
+-----------+
 - Fixed bug which would cause the module to lock up under rare conditions.
   (If a NWK ACK arrives just prior to a MAC ACK multiple times)
 
 - Fixed a bug which caused the DB command to return a 16-bit value rather than 8-bit.
 
 - Fixed a bug which caused the ST parameter to not get adjusted after a change of NH,NN,MT, or
   RN.

 - Fixed bug where a broadcast sent shortly after a unicast could cause packet tracking to not
   work on the broadcast resulting in duplicate copies of the same packet output. 

 - Fixed bug which caused Node Discoveries in a sleeping router network to be unreliable.

 - Fixed bug which caused the DN or ND+NI responses to be delayed.

 - Fixed bug which caused the ND responses to poorly utilize the available response time.

 - Fixed bug which caused multiple route discoveries to be initiated even when a route discovery
   to the same destination is already in progress.

 - Fixed a bug where changes to the SP/ST on a non-sleep coordinator would not take
   effect.

 - The .mxi file on the International builds listed the wrong range for the HP command.
