Maxima 5.28.0 release



Hi, I've created branch-5_28 in Git and tagged branch-5_28-base and
5.28.0. I've created tar.gz, srpm, and rpm's and uploaded them to the
SourceForge file manager. (http://sourceforge.net/projects/maxima/files)

Please give it a try & let us know how it turns out. If someone can
create a Windows installer, that will be terrific. (Special thanks to
David Billinghurst for his Herculean efforts on the Windows build
system.)

Happy computing,

Robert Dodier
