I created a ticket with the patch
http://www.isp-control.net/ispcp/ticket/1277
The new parameter to ispcp.conf is CHECK_FOR_UPDATES (yes/no) which by default is yes (current behaviour). Also, the patch is made in a way not to break current ispcp.conf installations that miss it (simply defaults are used in this case).
The parameter has effect only on the login page of the administrator. If you manually go to system tools->ispcp updates a check will be made regardless the status of CHECK_FOR_UPDATES parameter (which is good to have).
I'm pushing one more feature with this patch, which is the possibility to specify password parameters in the ispcp.conf file instead of modifying the source (PASSWD_STRONG and PASSWD_CHARS added).
I needed this as some of my accounts have long text-only passwords and will not be validated with the current ispcp.
