-2.0.7 - 12/16/00 
-   Modifications for Microsoft Visual C++ compilation 
-   Fixed core-dump bug in Array2dFile::labelsCopy() function (Ian Kay) 
+3.0.0alpha4
+
+       * ctsim: Fixed initialization of min/max for PlotFiles
+
+       * ctsim: Added reset to full-intensity scale menu item
+
+       * ctsim: Add conversion of projections to polar plot
+
+       * ctsim: improve bilinear scaling of image size
+       
+       * ezplot: Cleaned up y-tick label placement
+
+       * sgp: Added better support for projection/reconstruction animation
+       
+3.0.0alpha3 - Released 1/02/01
+
+       * ctsim: Added plotting of histograms
+       
+       * imagefile.cpp: fixed bug in generation of 16-bit PNG images
+
+       * ezplot.cpp: adjusted xtick label displays for better placement
+       
+3.0alpha2 - Released 1/02/01
+       
+       * 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.
+       
+       * sgp: Added linestyle settings
+       
+2.5.0 - 12/18/00 
+   First Microsoft Windows GUI version
+   Modifications for Microsoft Visual C++ compilation.

    Improved pjinfo to output binary headers and view data, useful
        when manually compiling phantoms that vary during projection
        process. Thanks to Ian Kay for idea and code submission.
