+
+v1.9.2, 2009/05/22
+Feature: Speed improvement by 100% by switching from simpleosc to pyliblo!
+ Drawback: pyliblo must be manually compiled on OS X
+
+v1.9.1, 2009/05/18
+Fix duplicate packet handling on OS X (again)
+
+v1.9.0, 2009/05/18 - first version towards a 2.0.0 release
+Completely reworked packet handling
+Memory reading and writing should be more robust now
+Reworked Initialization sequence
+BalanceBoard initialization on OS X should work now
+Fixed OS X compatibility by handling duplicate packets differently
+
+v1.8.2, 2009/05/12
+Feature: Nunchuk disconnection works properly
+
+v1.8.1, 2009/05/12
+Bugfix: BalanceBoard works now (IR must not be enabled on the BB; Setting the
+registers seems to influence the BalanceBoard's sensitivity.
+Note: On OS X the BalanceBoard sometimes does not work because of limitations
+in the Perfect Pairing Patch of OSCulator. Author contacted!
+
+v1.8, 2009/05/11
+Bugfix: Connection with inserted nunchuk fixed
+Bugfix: Restructure
+Feature: Removed some cmd-line arguments, thus making backend invocation easier
+Feature: Completely reworked initialization sequence
+
+v1.7.5, 2009/05/11
+Feature: Setup is now completely automatic, no need to configure anymore!
+Note: When Nunchuk is connected upon startup, connection fails sometimes!
+
+v1.7.4, 2009/05/09
+Bugfix: Fix for BalanceBoard Extension Controller
+Bugfix: Fix IR not working when Nunchuk connected (initialization error)
+
+v1.7.3, 2009/05/07
+Bugfix: Device not Found had a logical Error: it could never be reached
+Documentation updates everywhere in the code
+
+v1.7.2, 2009/05/06
+Bugfix: Duplicate Devices found on Win32 are now removed
+
+v1.7.1, 2009/05/06
+Bugfix: Fixed OSC IR sending code
+
+v1.7, 2009/05/05
+Feature & Bugfix: Correctly handle duplicate packets (mainly on OS X)
+
+v1.6.4, 2009/04/27
+Bugfix: Fixed Device Discovery OSC Message on OS X (Unicode String Problem)
+Cleaned up the code a bit
+
+v1.6.3, 2009/04/25
+Bugfix: Correctly exit on OS X
+Feature: OSC Message if no device was found
+
+v1.6.2, 2009/04/25
+Bugfix: Correctly handle OS X connection error
+
+v1.6.1, 2009/04/24
+Bugfix: Make backend correctly handle CTRL-BREAK
+
+v1.6, 2009/04/23
+Feature: Added Discovery Routine
+
+v1.5, 2009/04/21
+Bugfix: Fixed OS X Compatibility
+
+v1.4, 2009/04/20 (2:00 AM)
+Feature: Added support for Nyko Wireless Nunchuk by Sniffing the original handshake
+Feature: Added Status support
+Feature: Added support for Datel Wirelesse Nunchuk
+Feature: Insertion of a Nunchuk is now automatically detected and should be initialized automatically
+
+v1.3, 2009/04/03
+Feature: Moved existing code into Backend using Command-Line Parameters
+
+v1.2, 2009/03/31
+Feature: Added basic BalanceBoard support
+Bug: Fixed Extension Controller initialization sequence
+
+v1.1, 2009/03/17
+Feature: Added Nunchuk-Connection Check
+Feature: Added some more configuration variable on the top
+Feature: Added Nunchuk Buttons -> Nunchuk is now FULLY SUPPORTED!
+
+v1.0, 2009/03/17
+Feature: Added IR support in Nunchuk Mode
+Feature: Added ACC support in Nunchuk Mode
+Feature: Added OSC support for IR
+Feature: Added OSC support for Nunchuk Accelerometers
+
+v0.4, 2009/03/16
+Feature: Added (untested) Nunchuk support
+
+v0.3, 2009/03/13
+Bug: Fixed OS X compatibility (one MUST install lightblue using sudo!)
+
+v0.2, 2009/03/12
+Feature: Added OSC button support
+Feature: Added (untested) Mac support
+
+v0.1, 2009/03/06
+Feature: Initial OSC functionality (ACC only)
+Feature: Runs correctly on XP and Linux
+
+ToDo:
+* Cleanup the Code!
+* If no Nunchuk is present, but activated, C/Z are always activated!

+Frontend for wiipy_backend.py
+(c) 2009 Andreas Boehler, andreas.boehler@fh-linz.at, http://klasseonline.dyndns.org
+(c) 2009 Patrick Huebner, patrick.huebner@fh-linz.at
+
+Requirement:
+ * pybluez (Windows/Linux), lightblue (OS X)
+ * pyliblo (all platforms)
+
+Notes:
+ * wiimote_backend.py and wiimote_frontend.py need to be in the same dir!
+ * The current dir must be set to wiimote_[frontend|backend].py
+ * The Microsoft-BT Stack is NOT supported! Tested: Widcomm under XP
+ * The path in OS X must not contain spaces!
+
+v1.8, 2009/05/22
+Feature: Migrated to pyliblo from simpleosc which is a major speed improvement
+
+v1.7, 2009/05/11
+Feature: Removed setup sequence, initialization is now completely automatic; only left: debug
+
+v1.6.3, 2009/05/08
+Bugfix: Forgot int(msg) in disconnect-code
+
+v1.6.2, 2009/05/06
+Bugfix: Path to python.exe is now taken from sys.executable (should work on all platforms)
+
+v1,6.1, 2009/05/05
+Feature: Added debugging/verbose parameter support
+
+v1.6, 2009/04/28
+Feature: All OSC IPs and Ports can be freely configured now!
+
+v1.5.1, 2009/04/27
+Feature: Added ping command, status still to be done
+
+v1.5, 2009/04/26
+Bugfix: Correctly Terminate the process on MacOS X.
+
+v1.4, 2009/04/24
+Bugfix: Correctly Terminate the process on Win32. This took me about 6h to figure out!
+
+v1.3.1, 2009/04/23
+Bugfix: Changed from SIGKILL to SIGTERM for Unix kill method
+
+v1.3, 2009/04/23
+Feature: Added Device Discovery Routine
+Bugfix: Fixed Python 2.6 compatibility
+
+v1.2, 2009/04/23
+Bugfix: Frontend used 100% CPU because of infinite loop
+
+v1.1, 2009/04/20
+Bugfix: Fixed OS X Compatibility
+
+v1.0, 2009/04/09
+Bugfix: Fixed Windows Compatibility (tested on Vista)
+Note: Path to python.exe is hardcoded for now!
+
+v0.2, 2009/04/08
+Feature: Added OSC support
+
+v0.1, 2009/04/07
+Feature: Initial Version w/o OSC support
