As of march 2013 I have stopped maintaining cc65.
Oliver Schmidt, long time contributor to the libraries is providing support for the old version. See http://cc65.github.io/cc65/ for more information.
The old resources (main web page, docs, wiki, mailing list and FTP server) are still available for reference as long as there is demand. I will also try to help people with questions regarding the old version. Maybe with a little less priority than before:-)
