  • Add a new template function called $(format-flat-json), which generates
    flattened json output. This is useful for destinations, where the json
    parsing does not handle nested json format. (#2890)
  • Add ISO 8601 compliant week numbering. Use it with the ${ISOWEEK} macro
    and and all its variants: S_ISOWEEK, R_ISOWEEK and C_ISOWEEK. (#2878)
  • Add add-contextual-data() glob selector. It matches the message with shell
    style globbing. Enable it by setting selector(glob("$my_template") in the
    add-contextual-data() block. (#2936)
  • Add new rewrite operations to manipulate the timezone portion of timestamps have
    been added. set-timezone() to set the timezone value to a specific value,
    fix-timezone() to fix up an incorrectly recognized timezone and guess-timezone()
    to automatically deduce the timezone value on the assumption that the message
    is received in near real time. (#2818)
  • Send Server Name Identification (SNI) information with transport(tls).
    Enable it by setting the sni(yes) option in the tls block in your
    destination. (#2930)


  • templates: change the $LOGHOST macro to honour use-fqdn() (#2894)
  • Define syslog-ng-sysconfdir (#2932)

  • Fix SCL block parameter substitution of quoted escaped newline (#2901)
  • python, diskq, random-generator source: crash after failed reload (#2907)
  • Fix crash at shutdown on 32bit systems (#2893, #2895)
  • Invalidate the value of the LEGACY_MSGHDR macro in case either the PID or the PROGRAM
    macros are unset() using a rewrite rule. Previously LEGACY_MSGHDR would retain the old values. (#2896)
  • on 32bit platform diskq ftruncate could fail due to size 32/64 interface (#2892)
  • Support new tzdata format, starting from version 2009.XXX, in tzinfo parser. (#2898)
  • udp, udp6, tcp, tcp6, syslog, network destination: Correctly detect and set IP_MULTICAST_TTL
    in case of multicast ip address (#2905)
  • Fix hostname resolve on systems with only the loopback network interface configured (#2933)
  • wildcard-file(): Add multi-line(), pad_size() and multi-line-mode() option validation. (#2922)
