Major changes between sudo 1.8.18b3 and 1.8.18b2:

 * Fixed a bug where "sudo -l command" would indicate that a command
   was runnable even when denied by sudoers when using the LDAP or
   SSSD backends.

 * The match_group_by_gid Defaults option has been added to allow
   sites where group name resolution is slow and where sudoers only
   contains a small number of groups to match groups by group ID
   instead of by group name.

Major changes between sudo 1.8.18b2 and 1.8.18b1:

 * Fixed a use-after-free bug in visudo introduced in sudo 1.8.18b1.

 * Fixed a bug introduced in 1.8.17 where the SIGPIPE signal handler
   was not being restored when sudo directly executes the command.

Major changes between sudo 1.8.18b1 and 1.8.17p1:

 * The sudoers locale is now set before parsing the sudoers file.
   If sudoers_locale is set in sudoers, it is applied before
   evaluating other Defaults entries.  Previously, sudoers_locale
   was used when evaluating sudoers but not during the inital parse.
   Bug #748.

 * A missing or otherwise invalid #includedir is now ignored instead
   of causing a parse error.

 * During "make install", backup files are only used on HP-UX where
   it is not possible to unlink a shared object that is in use.
   This works around a bug in ldconfig on Linux which could create
   links to the backup shared library file instead of the current

 * Fixed a bug introduced in 1.8.17 where sudoers entries with long
   commands lines could be truncated, preventing a match.  Bug #752.

 * The fqdn, runas_default and sudoers_locale Defaults settings are
   now applied before any other Defaults settings since they can
   change how other Defaults settings are parsed.

 * On systems without the O_NOFOLLOW open(2) flag, when the NOFOLLOW
   flag is set, sudoedit now checks whether the file is a symbolic link
   before opening it as well as after the open.  Bug #753.

 * Sudo will now only resolve a user's group IDs to group names
   when sudoers includes group-based permissions.  Group lookups
   can be expensive on some systems where the group database is
   not local.

 * If the file system holding the sudo log file is full, allow
   the command to run unless the new ignore_logfile_errors Defaults
   option is disabled.  Bug #751.

 * The ignore_audit_errors and ignore_iolog_errors Defaults options
   have been added to control sudo's behavior when it is unable to
   write to the audit and I/O logs.
