* Fixed parsing of "Path askpass" and "Path noexec" in sudo.conf,
which was broken in version 1.8.4.
+ * On systems with an SVR4-style /proc file system, the /proc/pid/psinfo
+ file is now uses to determine the controlling terminal, if possible.
+ This allows tty-based tickets to work properly even when, e.g.
+ standard input, output and error are redirected to /dev/null.
+
+ * The output of "sudoreplay -l" is now sorted by file name (or
+ sequence number). Previously, entries were displayed in the
+ order in which they were found on the file system.
+
+ * Sudo now behaves properly when I/O logging is enabled and the
+ controlling terminal is revoked (e.g. the running sshd is killed).
+ Previously, sudo may have exited without calling the I/O plugin's
+ close function which can lead to an incomplete I/O log.
+
+ * Sudo can now detect when a user has logged out and back in again
+ on Solaris 11, just like it can on Solaris 10.
+
+ * The built-in zlib included with Sudo has been upgraded to version
+ 1.2.6.

What's new in Sudo 1.8.4p4?
* Fixed a bug introduced in Sudo 1.8.4 which prevented "sudo -v"
