[Security hardening] [Notification] haproxy (previously) failed to drop supplementary groups after setuid / setgid calls properly

just FYI notification that haproxy upstream has recently corrected 
improper dropping of supplementary groups  after setuid / setgid
We have further investigated this issue and have reasons to believe that
by itself this is NOT a security issue (another flaw would need to be
found in haproxy this to be actually possible to use for something interesting).
For now we are considering this fix to be a preventive measure / security
hardening (but took the time to notify you explicitly about this as you might
still want to backport it into affected versions).
Thank you && Regards, Jan.
