February '97 Svedberg 5.01 (intermediate versions not released)

	(1) Added optional new 'modified Fujita-MacCosham' fitting function
		for improved fitting of low molecular weight species in 
		conventional cells, and improved fitting before the meniscus
		is clear.
	(2) Increased the maximum number of species from 3 to 4.
	(3) Added ability to directly fit molecular weight (s/D) instead of D,
		and associated units form to specify units for MW.
	(4) Added ability to constrain s and/or MW values for one species to 
		a multiple of the value for another.  Thus if you believe the
		sample contains a mixture of monomer and dimer, you can force the
		sedimentation coefficient and/or s/D value for the dimer species
		to appropriate multiples of the properties of the monomer.
	(5) Increased maximum number of data files per fit from 9 to 40.
	(6) Improved computational speed for fitting ~3-fold and for Claverie 
		simulations ~7-fold by compiling portions of code.
	(7) Added ability to read XL-I interference data files, and a choice 
		between the file naming conventions of the new and old Beckman
		software.
	(8) Added the option of manually entering a meniscus position inside the
		radius of the first actual data point (often needed for 
		interference data).
	(9) For interference data, when the first data point in a data set is at
		a radius greater than the meniscus, the fitting functions adjust
		to account for the fact that the Beckman data acquisition defines
		this first data point to be zero.
	(10) The program default state is now to fit the baseline offset.
	(11) It is now possible to set a default specifying the font size to be 
		used when printing the results of fits.
	(12) Revised menu structure for graph formatting commands.
	(13) Help file to explain graph formatting and printing features.
		(Help file does not cover other aspects of the program, only the 
		graphing package common to SVEDBERG, XLGraph, and SEDNTERP).
	(14) New option on the "Printing Options" dialog box to force the use 
		of colors or black-and-white only.
	(15) New "Format...Legend" option that allows editing the text and other 
		properties of the graph legends.

March '95 Svederg 3.16 (intermediate versions not released)

	New options in Svedberg (thanks to Bo Demeler for suggesting these):
	(1) Instead of a residual plot in fit reports, you may optionally
		use an overlay of the data and fitted curves instead.
	(2) In residual plots, you may optionally automatically separate 
		the different data sets vertically so the residuals do 
		not lie on top of one another.

	The above options, and a couple of others formerly under the Analysis menu,
		are now found under a new Preferences menu.

	More Svedberg program and fitting options/defaults can be set via the 'Save
		Defaults to Disk...' choice under the File menu.

	Saved fits (.fit files) are now much smaller (old files are still okay).
	
	New 'Copy Graph Data to Disk' option in both programs under 
		the Edit Menu (suggested by Greg Ralston) allows you to
		copy graph data to a disk file (printable ASCII row/column
		data suitable for import into most programs).  This allows
		larger numbers of data points to be exported than can be 
		done via the Clipboard.  (Only 64 Kbytes can go to the 
		Clipboard, which is not sufficient for 9 data sets + fits).
		When data is written, the initial default is to separate
		columns of data with a tab character, but this default
		column delimiter can be set to a comma or space via the 
		'Save Defaults for Graphs...' choice in the graphics window.

	The error that occurs when trying to transfer too many data points
		to the Clipboard is now trapped and will give a warning 
		message to use the disk copy method instead.

---------------------------
February '95 Svedberg 3.13

	Fixed bug in installation program causing error during creation
	of program manager group and icons.

	Fixed bug in setting fit range for single data sets - file name
	shown on graph was erroneously that for next file, and this caused a
	crash if you tried to do it on the 9th file.

---------------------------
January '95 Svedberg 3.12 (intermediate versions not released)

	The control of loading of multiple file sequences
	has been placed on the File Enter/Alter form rather than within a
	separate dialog box, and this form has been re-arranged slightly.

	When you graph individual data sets (fit overlays,
	residuals, etc.) the selection of which data set to plot is done 
	via a separate floating window, which makes it easier to look through
	a series of scans one at a time. 

	The bug in Svedberg's Claverie simulation routine that affected 
	the results at the bottom of the cell has now been fixed (thanks 
	to Walt Stafford).	

	Graphics related menus have been re-arranged to correspond more 
	closely to typical Windows naming conventions.

	New options appear under the graphics Edit menu for adding offsets
	to different data series in a graph to separate them so they do 
	not overlap.  

	Other new options under the graphics Edit menu for copying or 
	pasting the data values from a graph to/from another program (e.g.
	Origin or a spreadsheet).  This provides a way to access the 
	calculated values in another program or to export graph data for 
	redrawing by your favorite graphics program.  Copying and pasting
	is done as tab-delimited tables of text, via the Clipboard.
	Copy/paste functions are also provided for the text strings which
	are used in the legends of multi-series graphs.

-----------------------
July '94 Svedberg 3.08

	Maintenance release: fixed bugs when printing margins went into 
	non-printable areas.  Minor adjustments to spacing around axis labels in graphs.
