Version 0.85
------------

	New Features

		* Added a ``transform to 0-1'' filter
		  (Revalues observations so that they
		   fall between 0 and 1)

		* 		

	Bug Fixes / Modifications

		* No more segfaults from Data->Rename->Cancel.
		  (thanks to Kyle Ferrio 
		  <kbf@zathras.greatmachine.org>).

		* Focus problems in edit window corrected.
		  (thanks to Kyle Ferrio 
		  <kbf@zathras.greatmachine.org>).

		* Summarize errors with varying variable
		  lengths corrected.
		  (thanks to Kyle Ferrio 
		  <kbf@zathras.greatmachine.org>).

		* Fixed Equality of Means bug
		  xldlas no longer fails with an 
		  X Window undrawable error.



Version 0.81
------------

	New Features

		* Will now compile with newer versions of XForms
		  (see README)

Version 0.80
------------

	New Features

		* A Test Menu.
		  Not many tests yet, but at least the structure
		  is now in place. It does include a Durbin-
		  Watson test (suggested by Wolfgang Koehler
		  <koehler@isis.wu-wien.ac.at>). Thanks to
		  Marti Rijken <mrijken@prv.gelderland.nl> for
		  sending me great info on tests; sorry I haven't
		  been able to incorporate it yet).

		* A Filters Menu.
		  Again, not many filters available (just detrend
		  and remove outliers), but more are coming.

		* First step taken in reducing ``modal''-ness
		  That is, the Graph window can be kept open while
		  other routines are performed.   

	Bug Fixes / Modifications

		* Added an "Assume Sample Data" option to preferences.
		  When selected, this will use one less degree of freedom
		  for the calculation of various statistics (ie. N-1 instead
		  of N). 

		* Median and Quartile calculations corrected to not round
		  to nearest integer.

		* Still more popup help balloons added.


Version 0.70
------------

	New Features

		* Sticky Windows. When you choose a location for "major"
		  xldlas windows, they will now reappear in the same
		  place (Suggested by Paul Vogel <vogel@boris.convex.com>).
 
		* Import Routines completely rewritten. No more freezes!
		  Also added command line options -icol and -irow to
		  import files on startup.

		* Added the following command line options:
 		  -h, -help, --help, -v, -version, --version
		  (Suggested by Paul Vogel <vogel@boris.convex.com>)
		
		* New Makefile. Just log on as root and type `make world'. 
		  (see the README file for details).

	Bug Fixes / Modifications

		* Histogram now handles missing values properly. Thanks to
		  Paul Vogel <vogel@boris.convex.com>
 
		* Lots of little bug fixes


Version 0.61
------------


	New Features

		* New distribution system. Source and binary are now split, 
		  with binary versions available for a variety of systems 
		  (ie. More than just Linux). See http://a42.com/~thor/xldlas
		  for details.


	Bug Fixes / Modifications

		* NN Fit no longer seg faults when fed missing observations.

		* Popup Balloon Helps now disappear correctly on menus.

		* Popup Balloon Helps added to more items.

		* Removed some non-ANSI stuff to ease compilation on other
		  platforms.

Version 0.60
------------

	New Features

		* Popup Balloon Help Added. These routines are based on
		  the tooltips library which is Copyright (C) 1996 Michael 
		  Chu (but it's GPL'd).
 
	Bug Fixes / Modifications

		* Summarize can now be performed on multiple variables. 
		  Suggested by N.V.Joshi <nvjoshi@ces.iisc.ernet.in>


Version 0.50
------------

	New Features

		* Optional PiCTeX format output of a Fitted Neural Network 
		  if a TeXLog is open.

		* Added some useful commandline options and wrote a man page 
		  for xldlas to explain them. See the file xldlas.1

	Bug Fixes / Modifications

		* GA Routine completely rewritten. Handles negative data 
		  better, and will try multiple terms for each independent 
		  variable.

		* You can now set the number of hidden nodes in an NN Fit.

		* HTML Log output now handles blank entries in tables in a 
		  nicer way.

		* Prob(F) output corrected.

		* Bug in Data --> Rename with long variable names fixed 
		  (Thanks to Tom Goddard <goddard@gpu.srv.ualberta.ca>)


Version 0.40
------------

	New Features


		* xldlas now has its own homepages on web space graciously 
		  provided by Linux Journal and SunSITE Hungary. In North 
		  America, go to:
	
		  http://a42.com/~thor/xldlas/
	
		  in Europe, try:

		  http://sunsite.math.klte.hu/mirrors/xldlas/

		* HTML Format log files - See HTML Log under the Log menu and 
		  the relevant Help entry.

		* NN Fit - Fitting Data with a Neural Network Try it out under
		  the Analysis menu, see the relevant help, and the addition
		  to Tutorial 3.

	Bug Fixes / Modifications

		* Suggested location on sunsite changed from
		  pub/Linux/apps/math to pub/Linux/X11/xapps/math
	
		* Added horizontal scrolling to the main window. It is now 
		  possible to see all output without having to resize the 
		  window.

		* Graph window now allows you to set x and y ranges (useful 
		  for making sets of graphs with identical axis).

		* xldlas no longer seg faults when you try to import more 
		  observations than MAX_OBS (Now you get a nice warning 
		  instead). (thanks to  Hans Zoebelein  
		  <zocki@goldfish.cube.net>) 

		* Third regression table output changed so that TeXLog works 
		  properly.
		
		* Default Line Styles in Plot menu are now sequential rather 
		  than all equal to one. (Thanks to Hans Zoebelein
		  <zocki@goldfish.cube.net>) 

		* The graph output format and options now work properly when 
		  changed from the graphing window.

Version 0.30
------------

	New Features:

		* One Way and Two Way Analysis of Variance (ANOVA). Try it out 
		  under the Analysis menu. See help Analysis --> ANOVA  and 
		  the fourth tutorial. (suggested by Richard B. Kreckel
		  <kreckel@iphcip1.physik.uni-mainz.de>)

		* Scatter Plots. Just double-click on a highlighted variable's
		  name in the Y-Variable browser (in the plotting window) 
		  and set the line type to 0. (suggested by Tom Fawcett 
		  <fawcett@nynexst.com>)

		* Regression output now includes probability values. The 
		  F-Test of the regression and the t-tests for coefficient 
		  estimates are now included, so you can see their 
		  significance without having to look up any values in 
		  distribution tables.


	Bug Fixes / Modifications:

		* Changed object gravity in most windows so that resizing 
		  works sensibly.(thanks to Richard B. Kreckel
		  <kreckel@iphcip1.physik.uni-mainz.de>)

		* Log and TeXLog now activated even if you don't hit return 
		  in the file name requestor.
		  (thanks to Tom Fawcett <fawcett@nynexst.com>)

		* Temporary files are much improved and are actually removed 
		  when xldlas is finished with them.(thanks to Richard B. 
		  Kreckel <kreckel@iphcip1.physik.uni-mainz.de>)

		* External declaration of **environ variable, which
		  is apparently useful for compiling under Solaris (and
		  should have been there for Linux in any case). 
		  (thanks to John Bazik <jsb@cs.brown.edu>).

		* Generate operations on (current) now work. That is
		  you can +,-.*,/ (current) and the data actually
		  changes.
