Sudo version 1.7.3 is now available. This version adds support for
logging a command's input and output. A new utility, sudoreplay,
is provided to play back sessions.

Major changes between sudo 1.7.2p8 and 1.7.3:
* Support for logging I/O for the command being run.
For more information, see the documentation for the "log_input"
and "log_output" Defaults options in the sudoers manual. Also
see the sudoreplay manual for how to replay I/O log sessions.
* The use_pty sudoers option can be used to force a command to be
run in a pseudo-pty, even when I/O logging is not enabled.
* On some systems, sudo can now detect when a user has logged out
and back in again when tty-based time stamps are in use. Supported
systems include Solaris systems with the devices file system,
Mac OS X, and Linux systems with the devpts filesystem (pseudo-ttys
* On AIX systems, the registry setting in /etc/security/user is
now taken into account when looking up users and groups. Sudo
now applies the correct the user and group ids when running a
command as a user whose account details come from a different
source (e.g. LDAP or DCE vs. local files).
* Support for multiple 'sudoers_base' and 'uri' entries in ldap.conf.
When multiple entries are listed, sudo will try each one in the
order in which they are specified.
* Sudo's SELinux support should now function correctly when running
commands as a non-root user and when one of stdin, stdout or stderr
is not a terminal.
* Sudo will now use the Linux audit system with configure with
the --with-linux-audit flag.
* Sudo now uses mbr_check_membership() on systems that support it
to determine group membership. Currently, only Darwin (Mac OS X)
* When the tty_tickets sudoers option is enabled but there is no
terminal device, sudo will no longer use or create a tty-based
ticket file. Previously, sudo would use a tty name of "unknown".
As a consequence, if a user has no terminal device, sudo will
now always prompt for a password.
* The passwd_timeout and timestamp_timeout options may now be
specified as floating point numbers for more granular timeout
* Negating the fqdn option in sudoers now works correctly when sudo
is configured with the --with-fqdn option. In previous versions
of sudo the fqdn was set before sudoers was parsed.
