DIA Release Notes

Release Notes for Version 40002675_L (2.3.0.7):

Core System Changes

* DIA will now detect and issue a warning if an instance is
  already running on the system

  logger would corrupt the log was fixed.

Device Changes

* Device Drivers added for the following Transport I/O cards
  - Telemetry1

* date/time of the dia.zip creation (by make.py) is now saved in
  file zip_build_date.py, which is stored in the root directory of
  the dia.zip file. The line "from zip_build_date import DIA_ZIP_BUILD_DATE"
  causes DIA_ZIP_BUILD_DATE to be a string like "2013-02-06T20:58:45Z". This is
  used by the "build_date" channel of the info_device driver.
  
* new InfoDevice, which allows the users to add static Dia data channels
  such as name, version, build_date, and so on. 
  
* Xbee Sensor driver (for L\T\ and \L\T\H Sensor) have settings added to support use of 
  degrees Fahrenheit and adding a calibration offset. 
  
* Added the 'calls' tracer level to ESP smart editor files. Is lower than 'debug', for 
  use with very simply 'method entry' messages useful when debugging 
  inheritance issues.
  
* Changed the RCI handler to accept multiple commands within a single
   block. Commands are executed from top to bottom. Previous
  commands can affect the state of subsequent commands. Failed commands
  do not affect the state of other commands.

      commands in a single payload.
