New: Variable localhost gives the Host setting from the service
config.

and : throughout most of IPS. Could mean changes to scripts and
applications dealing with date or time values from IPS.

*WARNING* Activating this breaks the FTP standard for the active
connection.
Fix: SITE IDLE command failed if a very large or

not that it ever was.
Mod: New setting in [GLOBAL] in main.cfg
named GroupsDefined is added to list all defined groups.

are the last IP the user connected from.
Fix: Various bugs in
the example RexxHook scripts fixed.

Mod: scr\* directory divided into multiple subdirectories by default, this means that the old standard FTPd scripts are moved into scr\ftpd\*.
New: All system read only variables are now available from within SMTPd and POP3d also. See updated list.
