Hi,
I've tagged version-5_21_0 in CVS and built tar.gz and rpms and posted
them to the Sourceforge file manager.
See: http://sourceforge.net/projects/maxima/files
If someone can build & upload a Windows installer, that would be great.
Please give it a try, As before we'll go through a few versions to
get something stable and then make a general announcement.
best
Robert Dodier
