-3.0.0beta1 - Released
+3.5.0 - Released 4//01
 
-	* global: Projection files are not compatible with previous version
-	due to new scanner definitions.
+	New Features:
+
+	-- ctsim: Added direct Fourier reconstructions (Thanks to 
+	Edgar Angeles for help with understanding FFT symmetry of
+	the projections)
 	
-	* global: deleted concept of field-of-view and added
-	  view ratio and scan ratio concepts.
+	-- ctsim: Added tips to be displayed at startup and via the help menu.
+	-- ctsim: Added center-detector concept. Allow for detector array
+	to be any arbitrary distance from center of scanner. As a result,
+	projection files are not incompatible with previous version of
+	CTSim.
+	-- ctsim: Added background and SMP processing for reconstructions, 
+	scanning, and rasterization. 
+	-- ctsim: Added generic threaded tasks and background manager for 
+	background processing as well as taking advantage of multiple-CPU's 
+	on SMP systems.
+	-- ctsim: Added plot t-theta sampling to projection file menu.
+	-- ctsim: Added Reconstruction with Rebinning for faster
+	divergent beam reconstructions.
+	-- ctsim: Added import and export of DICOM image files.
+	-- ctsim: Added PPM, PGM, and PNG file import to imagefile.
+	-- ctsim: Added FFT/IFFT of columns of image files.
+	-- ctsim: Added clipboard cut/copy/paste for image files.
+	-- ctsim: Added region of interest to reconstructions.
+	-- ctsim: Added Convert Rectangular Image to Projection files
+	-- ctsim: Added "Verbose Logging", "Startup Tips", and
+	"Background processes" options 	to Preferences dialog.
+	-- ctsim: Added plotting of projection file histograms.
+	-- plotfile: Added scattergram plot functions
+	-- ctsim: Added accelerator key for File-Properties
+	-- ctsim: Improved wireframe 3-d display to remove hidden
+	surfaces.
+	-- views.cpp: Added out of memory checks to display for huge
+	image and projection files.
+	-- backprojectors.cpp: Added setting of axis extent and increment
+	to reconstructions.
+	
+	Bug Fixes:
+	-- filter.cpp: Fixed Hanning parameter to be 0.5 rather than 0.54
+	-- imagefile.cpp: Fixed scaling factor in fftRows
+	-- imagefile.cpp: Fixed bug when performing magnitude() on real-valued
+	image.
+	-- sgp.cpp: Fixed bug in drawCircle.
+	-- distribution: fixed problem with documentation files not
+	being included with the distribution [Reported by Ian Kay].
+	-- sgp.cpp/ezplot.cpp: Improved plotting with markers.

+3.0.2 - Released 2/20/01

+	divergent projections into polar form.
+	
+3.0.1 - Released 2/19/01
+
+	* ctsim: Fixed dialog box for reconstruction so that
+	rotation angle setting will stay fixed in-between use

+	* ctsim: MSVC optimization bug work-around, compiler 
+	options changed.

+	* ctsim: Improved accelerator key handling
+	
+	* global: Added Hanning filter.
+
+	* global: Improved default parameters to that all defaults give
+	sensible output.
