The differences and new features are described in the file /exp/rcf/share/share/emacs/19.30/etc/NEWS.
The lisp files are now found in /exp/rcf/share/share/emacs/19.30/lisp. The site-lisp files are in /exp/rcf/share/share/emacs/site-lisp
Due to problems with some of the site-lisp files, we will not be installing emacs-19.30 as the default emacs program yet. Please try it out though, and send mail to system@cs.umass.edu with any problems you encounter using it.
Due to conflicts with the previous site-lisp files in /exp/rcf/common/lib/emacs/site-lisp/ , this path should not be added to the load-path. The default load-path in emacs.new already has the new site-lisp directory in it.
