Major changes between sudo 1.9.8p1 and 1.9.8:

 * Fixed support for passing a prompt (sudo -p) or a login class
   (sudo -c) on the command line.  This is a regression introduced
   in sudo 1.9.8.  Bug #993.

 * Fixed a crash with "sudo ALL" rules in the LDAP and SSSD back-ends.
   This is a regression introduced in sudo 1.9.8.  Bug #994.

 * Fixed a compilation error when the --enable-static-sudoers configure
   option was specified.  This is a regression introduced in sudo
   1.9.8 caused by a symbol clash with the intercept and log server
   protobuf functions.

Major changes between sudo 1.9.8 and 1.9.7p2:

 * It is now possible to transparently intercepting sub-commands
   executed by the original command run via sudo.  Intercept support
   is implemented using LD_PRELOAD (or the equivalent supported by
   the system) and so has some limitations.  The two main limitations
   are that only dynamic executables are supported and only the
   execl, execle, execlp, execv, execve, execvp, and execvpe library
   functions are currently intercepted. Its main use case is to
   support restricting privileged shells run via sudo.

   To support this, there is a new "intercept" Defaults setting and
   an INTERCEPT command tag that can be used in sudoers.  For example:

    Cmnd_Alias SHELLS=/bin/bash, /bin/sh, /bin/csh, /bin/ksh, /bin/zsh
    Defaults!SHELLS intercept

   would cause sudo to run the listed shells in intercept mode.
   This can also be set on a per-rule basis.  For example:

    Cmnd_Alias SHELLS=/bin/bash, /bin/sh, /bin/csh, /bin/ksh, /bin/zsh
    chuck ALL = INTERCEPT: SHELLS

   would only apply intercept mode to user "chuck" when running one
   of the listed shells.

   In intercept mode, sudo will not prompt for a password before
   running a sub-command and will not allow a set-user-ID or
   set-group-ID program to be run by default.  The new
   intercept_authenticate and intercept_allow_setid sudoers settings
   can be used to change this behavior.

 * The new "log_subcmds" sudoers setting can be used to log additional
   commands run in a privileged shell.  It uses the same mechanism as
   the intercept support described above and has the same limitations.

 * Support for logging sudo_logsrvd errors via syslog or to a file.
   Previously, most sudo_logsrvd errors were only visible in the
   debug log.

 * Better diagnostics when there is a TLS certificate validation error.

 * Using the "+=" or "-=" operators in a Defaults setting that takes
   a string, not a list, now produces a warning from sudo and a
   syntax error from inside visudo.

 * Fixed a bug where the "iolog_mode" setting in sudoers and sudo_logsrvd
   had no effect when creating I/O log parent directories if the I/O log
   file name ended with the string "XXXXXX".

 * Fixed a bug in the sudoers custom prompt code where the size
   parameter that was passed to the strlcpy() function was incorrect.
   No overflow was possible since the correct amount of memory was
   already pre-allocated.

 * The mksigname and mksiglist helper programs are now built with
   the host compiler, not the target compiler, when cross-compiling.
   Bug #989.

 * Fixed compilation error when the --enable-static-sudoers configure
   option was specified.  This was due to a typo introduced in sudo
   1.9.7.  GitHub PR #113.
