Changelog
Oct-25-2007 - Release V1.0

Nov-07-2007 - Release V1.1
	Changes to V1.0:
	- All panel colors 'Conform to system colors' 
	- Measurement data file: added with x- and y-scale around wavefront data array
	- Measurement data file: wavefront data array is limited to pupil interior if option is enabled
	- Measurement stop updates also hidden graphs
	- Bug removed: sign of y beam centroid corrected, mirrored pupil y position in beam view
	- Bug removed: too long spot shifts displayed at highest resolution
	- Bug removed: re-calculation of pupil when bound to beam diameter or centroid

Dec-06-2007 - Release V1.2
	Changes to V1.1:
	- Usage of updated camera driver version 3.10
	- Bug removed: fixed wavefront unit in 3D diagram, .csv file and via DataSocket (switch from µm to waves failed)
	- Control 'Hide data outside pupil' in wavefront graph config removed,
	  function is now bound to setup control 'Limit wavefront calculation and display to pupil interior'
	- BeamView graph improved, undetectable spot areas are displayed now black without strong color gradients
	- Bug removed: off-center pupil position caused calculation error in wavefront statistics 
	- Wavefront output in csv file in normal order: y array index increases downwards but y-coordinate increases upwards

Dec-17-2008 - Release V1.3
	Changes to V1.2:
	- Program shut down in case of busy computer prevented by longer timeout of 10 sec
	- New camera driver uv480 version 3.30 provided and required
	- uc480 Camera Manager.exe is removed after camera driver installation to prevent erasure of WFS calibration data
	- Wavefront color spectrum relates to manual set min and max z-axis, not to wavefront data content
	- Extend allowed exposure range to 65 ms

Jun-24-2009 - Release V1.4
	Changes to V1.3:
	- Support of new models WFS150-7AR and WFS150-5C
	- Bug fixed: Zernike results were always related to image center, now related to pupil, also when off-center!
	- Bug in driver version comparison fixed
	- Required camera driver version updated to 3.32
	- Live spot centroid data transfer added to DataSocket interface
	- Max size of centroid data arrays reduced by 1 (same size as wavefront array)
	- DataSocket config stored in registry
	- Configurations file (.cfg) enables storage and reload of application settings
	- Wavelength range limited to 300 - 1100 nm (WFS150-5C)

Dec-11-2009 - Release V2.0
	Changes to V1.4:
	- Support of new model WFS300-14AR with exchangeable Microlens Array
	- Support of multiple Microlens Array calibrations within one WFS instrument
	- Separate instrument driver WFS_Drv available, LabView support and samples
	- Bug removed: Zernike results went high when pupil y position was shifted off-center
	- Trigger functionality added
	- DataSocket interface: centroid array data type changed from double to float

Apr-14-2010 - Release V2.1
	Changes to V2.0:
	- Combined install package for application, instrument driver and camera USB driver
