Is there information about bugs and will there be “fixpacks”?
Yes, the most recent information about bugs will be available via http://set.gmd.de/~veit/os2/xf86bugs.html (sometimes updated every hour or day). The HTML files linked in this WWW tree are available through FTP as well: set.gmd.de /pub/misc/XFree86OS2/html/* Fixes that become available are at /pub/misc/XFree86OS2/fixes/*.
