Dr. Volker, Two security issues have been reported in GnuTLS: https://www.gnutls.org/security.html#GNUTLS-SA-2016-2 https://www.gnutls.org/security.html#GNUTLS-SA-2016-3 At this point, I think the best way to proceed would be to: 1) release 3.3.24 with the patch for the latter, then; 2) update to 3.4.15, which involves an ABI break. -- Yaakov
