"[#<n>]" below refers to ticket <n> at
https://arc.liv.ac.uk/trac/SGE/ticket/<n>.  For historical reasons,
changes due to Univa/Sun are tagged as "[U]", or "[(U)]" if partially
due to them or appearing first in this version.

 * submit jobs in a SystemD friendly manner.
   Prerequisite:
     Exec hosts must be running Linux with SystemD (tested on Centos 7)
     There must be a binary "/bin/systemd-run" located on the exec hosts

Version 8.1.9
-------------

* Security

    methods
  * distinst supports installation with install(1) for use with -local

* Incompatible changes

  * The CA directory is now /var/lib/sgeCA instead of /var/sgeCA

    version built with qsort_args (as above), which will make live
    upgrades from such a version fail on nodes running parallel jobs

* Other changes

  * Extensive internal changes to improve robustness, e.g. of
    string-handling against buffer overruns -- somewhat error-prone
    and may have caused regressions; more required

  The first fix is for a trivial remote root by a valid user.  The
  others, including fixes for potential buffer overruns in daemon and
  setuid programs, may or may not be exploitable.

  * Sanitize the environment before executing remote startup programs etc.
    Somewhat incompatible:  LD_LIBRARY_PATH etc. may need to be set
    differently.  See the security notes in remote_startup(5) and
    sge_conf(5).  (CVE-2012-0208, thanks to William Hay)
  * Don't write initial log messages in /tmp [#508].  Somewhat
    incompatible:  initial messages now in syslog.
  * Avoid using mktemp.  (Probably not a significant problem.)
  * Control core dumps under setuid etc. with SGE_ENABLE_COREDUMP.
    (Not normally a security issue.)
  * Bounds checking in replace_params [#215]
