* Fixed a warning on macOS introduced in sudo 1.8.29 when sudo
attempts to set the open file limit to unlimited. Bug #904.
* Sudo now closes file descriptors before changing uids. This
prevents a non-root process from interfering with sudo's ability
to close file descriptors on systems that support the prlimit(2)
system call.
* Sudo now treats an attempt to run "sudo sudoedit" as simply
"sudoedit". If the sudoers file contains a fully-qualified path
to sudoedit, sudo will now treat it simply as "sudoedit" (with
no path). Visudo will will now treat a fully-qualified path
to sudoedit as an error. Bug #871.
* Fixed a bug introduced in sudo 1.8.28 where sudo would warn about
a missing /etc/environment file on AIX and Linux when PAM is not
enabled. Bug #907
* Fixed a bug on Linux introduced in sudo 1.8.29 that prevented
the askpass program from running due to an unlimited stack size
resource limit. Bug #908.
* If a group provider plugin has optional arguments, the argument list
passed to the plugin is now NULL terminated as per the documentation.
* The user's time stamp file is now only updated if both authentication
and approval phases succeed. This is consistent with the behavior
of sudo prior to version 1.8.23. Bug #910
* The new allow_unknown_runas_id sudoers setting can be used to
enable or disable the use of unknown user or group IDs. Previously,
sudo would always allow unknown user or group IDs if the sudoers
entry permitted it, including via the "ALL" alias. As of sudo
1.8.30, the admin must explicitly enable support for unknown IDs.
* The new runas_check_shell sudoers setting can be used to require
that the runas user have a shell listed in the /etc/shells file.
On many systems, users such as "bin", do not have a valid shell
and this flag can be used to prevent commands from being run as
those users.
* Fixed a problem restoring the SELinux tty context during reboot
if mctransd is killed before sudo finishes. GitHub Issue #17.
* Fixed an intermittent warning on NetBSD when sudo restores the
initial stack size limit.
