Aug 17/07 - Release xcrvfit v4.0.8. Lots of cool stuff, see the documentation. Iwould still say this is a preliminary release. I mean, I haven't even tried the linux version yet (placing great faith in my installation tools). The program works well enough for me make the manual so may as well get on with it and face the critics. And yeah, based on fixed releases (up to 8) it is hard to get this software working just right. I really don't know if people like this multiple dataset analysis stuff or not...

Jan 15/04 - Pascal Mercier ported xcrvfit to macOSX aqua. You must then move the folder to /Applications before clicking on the xcrvfit icon. Pascal implemented xcrvfit with a File menu to navigate through data files. I also found that I didn't like the default font selection which I changed via the Options menu. I haven't officially started to support this version yet, but your email would certainly encourage me to do so. You will also need mac tcl/tk to run xcrvfit and that is available at:

Feb 26/03 - Fixed bug with writing out the xcrvfit defaults file. The bug happened when you changed any settings with the "setup graphics" button.

Dec 30/02 - Removed expiry date from this latest version, updated web pages. The manual has been re-formatted into a nice standardized document.
