* Fixed the sample_approval plugin's symbol exports file for systems
where the compiler doesn't support symbol hiding.
* Fixed a regression introduced in sudo 1.9.1 where arguments to
the "sudoers_policy" plugin in sudo.conf were not being applied.
The sudoers file is now parsed by the "sudoers_audit" plugin,
which is loaded implicitly when "sudoers_policy" is listed in
sudo.conf. Starting with sudo 1.9.3, if there are plugin arguments
for "sudoers_policy" but "sudoers_audit" is not listed, those
arguments will be applied to "sudoers_audit" instead.
What's new in Sudo 1.9.2
* Fixed package builds on RedHat Enterprise Linux 8.

Notes on upgrading from an older release
========================================
o Upgrading from a version prior to 1.9.3:
Starting with version 1.9.3, sudoers rules must end in either
a newline or the end-of-file. This makes it possible to provide
better error messages. Previously, it was possible to include
multiple rules on a single line, separated by white space.
Starting with version 1.9.3, sudo will attempt to recover from
a syntax error in the sudoers file by discarding the portion
of the line that contains the error until the end of the line.
To restore the historic behavior of refusing to run when a
syntax error is encountered, add "error_recovery=false" as a
plugin option in sudo.conf for the "sudoers_audit" plugin, (or
"sudoers_policy" if there is no "sudoers_audit" plugin configured).
o Upgrading from a version prior to 1.9.1:
Starting with version 1.9.1, sudoers plugin arguments in sudo.conf
should be specified for the "sudoers_audit" plugin, not
"sudoers_policy". This is because the sudoers file is now
opened and parsed by the "sudoers_audit" plugin. Previously,
this was done by the "sudoers_policy" plugin. The use of an
audit plugin makes it possible for the sudoers module to detect
when a command has been rejected by an approval plugin and only
log commands that are allowed by both policy and approval
plugins.
o Upgrading from a version prior to 1.8.30:
Starting with version 1.8.30, sudo will no longer allow commands
