+What's new in Sudo 1.8.28
+
+ * Sudo will now only set PAM_TTY to the empty string when no
+   terminal is present on Solaris and Linux.  This workaround is
+   only needed on those systems which may have PAM modules that
+   misbehave when PAM_TTY is not set.
+
+ * The mailerflags sudoers option now has a default value even if
+   sendmail support was disabled at configure time.  Fixes a crash
+   when the mailerpath sudoers option is set but mailerflags is not.
+   Bug #878.
+
+ * Sudo will now filter out last login messages on HP-UX unless it
+   a shell is being run via "sudo -s" or "sudo -i".  Otherwise,
+   when trusted mode is enabled, these messages will be displayed
+   for each command.
+
+ * On AIX, when the user's password has expired and PAM is not in use,
+   sudo will now allow the user to change their password.
+   Bug #883.
+
+ * Sudo has a new -B command line option that will ring the terminal
+   bell when prompting for a password.
+
+ * Sudo no longer refuses to prompt for a password when it cannot
+   determine the user's terminal as long as it can open /dev/tty.
+   This allows sudo to function on systems where /proc is unavailable,
+   such as when running in a chroot environment.
+
+ * The "env_editor" sudoers flag is now on by default.  This makes
+   source builds more consistent with the packages generated by
+   sudo's mkpkg script.
+
+ * Sudo no longer ships with pre-formatted copies of the manual pages.
+   These were included for systems like IRIX that don't ship with an
+   nroff utility.  There are now multiple Open Source nroff replacements
+   so this should no longer be an issue.
+
+ * Fixed a bad interaction with configure's --prefix and
+   --disable-shared options.  Bug #886.
+
+ * More verbose error message when a password is required and no terminal
+   is present.  Bug #828.
+
+ * Command tags, such as NOPASSWD, are honored when a user tries to run a
+   command that is allowed by sudoers but which does not actually
+   exist on the file system.  Bug #888.
+
+ * Asturian translation for sudoers from translationproject.org.
+
+ * I/O log timing files now store signal suspend and resume information
+   in the form of a signal name instead of a number.
+
+ * Fixed a bug introduced in 1.8.24 that prevented sudo from honoring
+   the value of "ipa_hostname" from sssd.conf, if specified, when
+   matching the host name.
+
+ * Fixed a bug introduced in 1.8.21 that prevented the core dump
+   resource limit set in the pam_limits module from taking effect.
+   Bug #894.
+
+ * Fixed parsing of double-quoted Defaults group and netgroup bindings.
+
+ * The user ID is now used when matching sudoUser attributes in LDAP.
+   Previously, the user name, group name and group IDs were used
+   when matching but not the user ID.
+
+ * Sudo now writes PAM messages to the user's terminal, if available,
+   instead of the standard output or standard error.  This prevents
+   PAM output from being intermixed with that of the command when
+   output is sent to a file or pipe.  Bug #895.
+
+ * Sudoedit now honors the umask and umask_override settings in sudoers.
+   Previously, the user's umask was used as-is.
+
+ * Fixed a bug where the terminal's file context was not restored
+   when using SELinux RBAC.  Bug #898.
+
+ * Fixed CVE-2019-14287, a bug where a sudo user may be able to
+   run a command as root when the Runas specification explicitly
+   disallows root access as long as the ALL keyword is listed first.
+
