v2.3.2

• Added Receive Packet frame type (0x90) definition.
• Added an optional timeout to wait_read_frame.

v2.3.1

• New features - Adds support for the Tornado I/O loop
• If your application already uses the Tornado I/O loop then integrating python-xbee should be a breeze. Check out the docs for usage and more details.

v2.3.0

• Python 3 compatibility bugfix in _build_command().
• Added Extended Modem Status frame type (0x98) frame definition.

v2.2.5

• Formatting tidy in line with PEP8 recommendations.
• Added 'create_source_route' and 'register_joining_device' Zigbee frame definitions.
• Moved version information to __init__.py.
• Fixed DigiMesh for Python 3.
• Fixed DigiMesh 'tx' frame definition.

v2.2.4

• Added DigiMesh support.
• Added support for Route Record Indicator, Many-to-One Route Request and Route Information packets.
• Improved and simplified tests.
• Documentation updates and comment typo corrections.
• Do not break on error, rather log error.
• Add Travis CI for unit tests.
• Modernized setup.py.

v2.2.3

• Fix README for GitHub and PyPI

v2.2.2

• Add error_callback function to XBeeBase.
• If an error_callback method is given to the XBeeBase constructor (in addition to the callback method), a new thread will automatically be spawned. This thread will read from the serial port and call the error_callback when an unexpected Exception (not ThreadQuitException) is raised while waiting for serial data. This generally indicates that the XBee serial interface needs to be reconnected.

v2.1.0

• Support for XBee ZB devices significantly improved.
• Now raises a KeyError with a useful message when a response that looks like a command is received. This helps debug devices that are not in API mode.
• Improper lengths for the ZigBee tx_explicit cluster and profile fields have been corrected.
• Removed auto-testing distutils extension for lack of easy cross-version compatibility.
• Now compatible with both Python 2.X and Python 3.X.
• Fixed bug in APIFrame.escape().
• Fixed crash where a failed call to Serial.read() could return nothing.
• Packet-parsing subsystem generalized to allow for much more general parsing behavior.
• ZigBee now parses IS command responses.
• Node Discover responses for ZigBee devices are now parsed.
• Added tests for escaped API communication.
• Fixes issue #31 on Google Code: parameter information for lowercase nd or is commands were not parsed.
• Closes issue 35, as reported by Mark Fickett.
• If an empty frame is received from a device, it is ignored.
• Removed deprecated build process files.
• Backported parsing of IS AT command response as I/O data from ZigBee devices.
• BACKWARDS-INCOMPATIBLE CHANGES (See the documentation for details):
• XBee IS "Force Sample" AT response (and Remote AT Response) 'parameter' value is no longer raw; it is parsed as I/O samples.
• ZigBee IS "Force Sample" AT response (and Remote AT Response) 'parameter' value is no longer raw; it is parsed as I/O samples.
• ZigBee ND "Node Discover" AT response (and Remote AT Response) 'parameter' value is no longer raw; it is parsed into a node discover dictionary.

v2.0.0

• Added preliminary support for XBee ZB devices; thanks Greg and Brian!
• Improved & unified sample data header parsing code.
• Improved documentation.

v1.9.2

• Fixed bug where _write() call on a serial object should have been write().
