plus a couple of minor changes.. Some highlights of the new stuff that was not in the old version: - remote access support.. full checkout/commit/log/etc.. - much improved dead file support.. - speed improvements - better $CVSROOT handling - $Name$ support - support for a "cvsadmin" group to cut down rampant use of "cvs admin -o" - safer setuid/setgid support - many bugs fixed.. :-) - probably some new ones.. :-( - more that I cannot remember offhand..
