   Access to search results URLs is now CSRF whitelisted, based on user
   feedback.
   An error in rt-email-dashboards has been corrected.

  3.8.13 Release Notes

   This release contains an important bugfix over the 3.8.12 security
   release:

    * Fix sending email with the 'perl-script' mod_perl handler, by
      ensuring that STDIN was always on FD 0 before calling IPC::Open2.
      This failure showed as either SIGPIPE or abnormal exit codes when
      running sendmail.

    * Fix for "Undefined value assigned to typeglob" and "Bad file
      descriptor: core_output_filter" errors caused by the above change, by
      ensuring that both FD 0 and FD 1 are prevented from being claimed by
      Apache.  This error only arose with the perfork MPM and mod_perl <=
      2.0.4.
