-2.5.1 - Released 12/30/00
+	TODO
+	Read PlotFile's.
+	Add to ctsim export of imagefiles to standard graphic formats.
 
-	* Added PlotFile class
-	* Added plotting of rows & columns to ctsim
-	* Updated if2 to output plot files
-	* Added y-axis scaling to plotting in ctsim
-	* Reworked statistics to share between imagefile and plotfile class
-	* Fixed scaling bug in rasterizing Phantom with nsample > 2
+
+3.0alpha2 
+	
+	* processsignal.cpp: Fixed "off by one" bug in
+	shuffleNaturalToFourierOrder when n is even.
+
+	* imagefile: Added FFTW library to imagefile processing
+
+	* ctsim: added generation of filter images
+	
+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.
+	
+	* sgp: Added linestyle settings
