• pmtelemetryd: gRPC data collection functionalities were added to
  the daemon. https://github.com/scuzzilla/mdt-dialout-collector is
  the library linked to add the functions required to collect data
  via gRPC dialout. Thanks to Salvatore Cuzzilla ( @scuzzilla ) for
  this contribution, along with the ninja support of Marc Sune
  ( @msune ).
• BMP daemon: HA support introduced: in order to add redundancy at
  data collection, let multiple collectors to establish indentical
  BMP session, while only one is sending data to the backend. Thanks
  to Zhuoyao Lin ( @Zephyre777 ) and Leonardo Rodoni ( @rodonile )
  for this contribution.
• nfacctd: developed a more robust and streamlined NetFlow v9/
  IPFIX template handling framework based on libcdada structures,
  hence dropping the previous ad-hoc home-grown memory structures.
• nfacctd: introduced support for sampling rate calculation based
  on IANA entities IE309 (samplingSize), IE310 (samplingPopulation),
  which are being exported in IPFIX sampling options for a random-n-
  out-of-N sampler. Also, support for 16-bit and 32-bit selectorID
  is added as well. Thanks to Leonardo Rodoni ( @rodonile ) for this
  contribution.
• nfacctd: extended the support of IE130 (exporterIPv4Address) and
  IE131 (exporterIPv6Address) for when this info is contained in
  data packets. Thanks to Leonardo Rodoni ( @rodonile ) for this
  contribution.
• nfacctd: added nfacctd_ignore_exporter_address config knob to
  not honour IE130 (exporterIPv4Address), IE131 (exporterIPv6Address)
  and use the socket address instead.
• nfacctd: improved support for Route Distinguisher (RD): added the
  case where the RD information has finer-grained scope in Option
  packets; also RD in IPFIX Options can now be used for correlating
  data against BGP/BMP. Finally priority of supplied RD info is
  streamlined as: RD in flow_to_rd.map > RD in IPFIX/NFv9 data
  packet > RD in IPFIX/NFv9 option packets. Thanks to Leonardo
  Rodoni ( @rodonile ) for these contributions.
• nfacctd: added IEs 44 (sourceIPv4Prefix), 170 (sourceIPv6Prefix),
  45 (destinationIPv4Prefix), and 169 (destinationIPv6Prefix) to
  flow heuristics.
• nfacctd: as part of src_mac, dst_mac primitives, added support
  for IEs 365 (staMacAddress) and 366 (staIPv4Address).
• nfacctd: introduced support for IE497 (srhSegmentIPv6ListSection),
  The SRv6 Segment List as defined in Section 2 of [RFC8754] as a
  series of octets in IPFIX. Also added Path Delay measurements
  PathDelay{Mean,Min,Max,Sum}DeltaUsecs.
• nfacctd: tunnel primitives (tunnel_src_host, tunnel_dst_host,
  tunnel_proto, tunnel_tos, tunnel_src_port, tunnel_dst_port and
  tunnel_tcpflags) were linked to SRv6 code. Also, in this context,
  support for repeating IEs has been added. Thanks to Uwe Storbeck
  ( @ustorbeck ) for this contribution.
• nfacctd: extended IE89 (forwardingStatus) support to be 2 or 4
  bytes long. Also introduced support for IE31 (flowLabelIPv6).
  Thanks to Uwe Storbeck ( @ustorbeck ) for these contributions.
• nfacctd: a new primitive 'nvgre' is defined representing the
  Tenant Network Identifier (TNI) for NVGRE L2 tunnels, which is
  encoded in IANA IE351 (layer2SegmentId) with MSB 0x02. Thanks to
  Leonardo Rodoni ( @rodonile ) for this contribution.
• sfacctd: added support for accounting for ARP packets via a new
  aggregate_unknown_etype config knob.
• nfacctd, sfacctd, pmacctd: added new 'in_cvlan' and 'out_cvlan'
  primitives. It identifies the VLAN to which the frame belongs to
  when it is transmitted in the customer network.
• BGP daemon: added support for "Only to Customer" OTC attribute,
  RFC9234.
• BGP daemon: extend MP nexthop length to support 48 bytes to fit
  the BGP VPNv6 nexthop length. Thanks to @FRIDM636 for this
  contribution.
• BGP daemon: as specified by RFC8950, routers cannot advertise
  IPv4 or VPNV4 routes with an IPv6 next hop without an extra
  capability advertisement (Extended Next Hop Encoding). This has
  been added so that the daemon can reply with this capability to
  the remote peer. Thanks to Leonardo Rodoni ( @rodonile ) for
  this contribution.
• BGP, BMP daemons: Two new configuration keys are introduced:
  bgp_comms_encode_as_array and as_path_encode_as_array to allow
  to specify that BGP communities and AS_PATH are encoded as an
  array in JSON or AVRO encodings.
• BMP daemon: a new bmp_dump_exclude_stats config knob has been
  added: if enabled, BMP Stats messages are not going to be cached
  and thus not being included in the regular dump.
• All daemons: added a -T / dry_run config knob. With the 'config'
  argument only configuration is validated; with the 'setup' one
  the daemon and its plugins are also instantiated and validated.
• Kafka plugin: allowing to configure sub-minute historical time
  bins (ie. kafka_history, etc.).
• pre_tag_map: introduced pre_tag_map_dont_recirculate config knob
  to explicitely disable v4/v6 recirculation of entries without an
  'ip' key specified. Also if 'ip' key is not defined, still define
  the address family (AF) so to be memory-savvy and avoid creating
  duplicate entries in case of v4/v6 recirculation.
• nDPI support: updated API calls to compile against nDPI 4.6. Also
  dropped support for previous versions of the library.
  ! fix, nfacctd: treat the result of (SysUptime - fstime) as signed
  to avoid a underflow in the case where fstime > SysUptime in
  NetFlow v9. Thanks to Jim Westfall ( @jwestfall69 ) for this
  contribution.
  ! fix, nfacctd: addressed a memory leak in handling NetFlow/IPFIX
  templates. Also performed code re-factoring to better encapsulate
  the template functionality, add a template header file, separate
  the module interface from local functions and reduce the scope of
  local functions. Thanks to Uwe Storbeck ( @ustorbeck ) for these
  contributions.
  ! fix, nfacctd: parsing of IPFIX/NetFlow data when a template does
  contain multiple padding octet fields IE 210 (paddingOctets) with
  different length. Thanks to Uwe Storbeck ( @ustorbeck ) for this
  contribution.
  ! fix, nfacctd: 4 bytes long IE95 (applicationID) is now supported;
  as part of this work the setup of nDPI and NBAR classifiers have
  been harmonized.
  ! fix, sfacctd: mispelled daemon type in sampling_direction handler
  was causing counters not to print.
  ! fix, pmacctd: restored packet data pointer for correct collection
  of ICMPv6 data.
  ! fix, uacctd: the daemon was crashing upon receipt an ICMP Echo
  Request packet (as a result, for example, of a ping). Thanks to
  Alexei A Smekalkine ( @ikle ) for this contribution.
  ! fix, pmtelemetryd: when no backend dump method is configured (and
  telemetry_dump_time_slots is not set) pmtelemetryd was crashing
  with SIGFPE. Also fixed the dump interval calculation when time
  slots are used. Thanks to Uwe Storbeck ( @ustorbeck ) for these
  contributions.
  ! fix, pmtelemetryd: restored ability of the daemon re-loading maps
  via SIGUSR2 signal. Thanks to Salvatore Cuzzilla ( @scuzzilla )
  for this contribution.
  ! fix, BGP, BMP daemons: the hash function used to distribute per-
  peer information attached to RIB entries was enriched with the
  addition of Route Distinguisher (RD) data in order to minimize
  collisions. It is in fact crucial to have an efficient hash-table
  to perform data correlation between BGP/BMP & IPFIX. Thanks to
  Salvatore Cuzzilla ( @scuzzilla ), Leonardo Rodoni ( @rodonile )
  for this contribution.
  ! fix, BMP daemon: finer grained control on support of ADD-PATH
  capability as part of the Peer Up message in order to support
  the case of remote peer receive-only scenario.
  ! fix, SQL plugins: 'in_vlan' primitive is not muxed anymore on
  'vlan' keyword at configure time. Also, 'out_vlan' primitive is
  now properly handled if sql_optimize_clauses left false.
  ! fix, MySQL plugin: if timestamps_utc is set to true, enforce UTC
  for the current session.
  ! fix, tee plugin: missing variable definition when BSD definition
  is on was preventing the code to compile correctly.
  ! fix, pre_tag_map: check added to avoid daemon hanging if 'next'
  label was mentioned as part of the last map entry.
  ! fix, Redis: avoid to create a new file descriptor for every
  reconnect. Use redisReconnect instead of redisConnect. Thanks to
  Uwe Storbeck ( @ustorbeck ) for this contribution.
  ! fix, util.c: weekly time roundoff has been made consistent by
  correctly including the first day of the week.
  ! fix, util.c: when pidfile is specified, use mkdir_multilevel() to
  build dir structure if needed.
  ! fix, plugins_hook.c: when processing a pcap_savefile, perform an
  inter-buffer sleep of 1ms only if using home-grown buffering as
  ZeroMQ (plugin_pipe_zmq) would instead do fine absorbing the data
  burst.
  ! fix, rpki_msg.c: missing json_decref() in rpki_roas_file_load()
  was leaking memory on map reload. Also, solved a SEGV observed at
  times when reloading rpki_roas_file. Finally free'd the output of
  aspath_make_str_count() in rpki_roas_file_load().

• pmtelemetryd: removed legacy Python decoders and associated utils,
  also removed support for Kafka and ZeroMQ telemetry collection.
• pre_tag_map: obsoleted 'fwdstatus' key.
• GeoIP support: removed support for Maxmind API v1.
