Hi,
I've tagged Maxima 5.23.0 in CVS as version-5_23_0 and
built rpms and uploaded rpms & source code to the SF file manager.
http://sourceforge.net/projects/maxima/files/
If someone can create a Windows and/or Mac package,
that would be great.
Hope you can give it a try and let us know whether it works.
As ever, we 'll try to get to a stable release after a few tries
and make a general announcement then.
best
Robert Dodier
