+3.0alpha2 - Released 1/01/01
+	
+ 	* ctsim: All functions of command-line tools are now in graphical ctsim
+	
+	* ctsim: added generation of filter images
+
+	* ctsim: Added 2-image math functions (mul, add, div, sub)
+
+	* ctsim: Added export of imagefiles to graphic file formats
+
+	* ctsim: Added support for scaling imagefiles in new sizes
+
+	* ctsim: Added ability to save standard phantom definitions as
+	text files suitable for reading.
+	
+	* ctsim: Add labels for image transformations and display of labels
+	when performing properties of images.
+
+	* processsignal.cpp: Fixed "off by one" bug in
+	shuffleNaturalToFourierOrder when n is even. Moved functions to
+	fourier.cpp
+
+	* imagefile.cpp: Added FFTW library to imagefile processing. Converted
+	image math functions to complex-valued math.
+
+	* phantom.cpp: Added ability to save phantom files as ASCII text.
+	
+3.0alpha1 - Released 12/29/00
+
+	* Added PlotFile class to system, used by if2 and ctsim for row
+	and column plots and comparison plots
+
+	* ctsim: Added image comparison statistics and image subtraction
+
+	* ctsim: Added plotting of rows & columns with y-axis scaling 
+
+	* ctsim: Added row and column plot comparisons between two image
+	files.
+
+	* ctsim: Added "Process" menu to image file display with math
+	functions. Added 2-dimensional inverse Fourier to math
+	functions. Added support for complex (real/imaginary) images.
+
+	* mathfuncs.cpp: Reworked statistics algorithm to share between
+	imagefile and plotfile classes.
+
+	* imagefile.cpp: Fixed scaling bug when rasterizing Phantom with
+	nsamples > 2.  Added generic mage math functions, moved from
+	if1.cpp and if2.cpp to imagefile.cpp. Added support complex
+	images.
+
+	* array2dfile.cpp: Added code to support complex (real/imaginary)
+	images.
+
+	* if1: Updated to handle error conditions, such as sqrt of a
+	negative number. Converted to use new ImageFile math functions.
+	
+	* if2: Updated to output plot files and use new ImageFile class
+	math functions
+
+	* if1: Updated to use new ImageFile class math functions
+
+	* ezplot: Reworked to better store colors/linestyles/symbols with
+	individual curves. Improved display of labels and ticks. Updated
+	to use POL class member variable. Updated to more C++ conventions.
+
+	* pol: converted to C++ class. Extracted HashTable to separate
+	class.
