• Introduced support for eBPF for all daemons: if SO_REUSEPORT is supported by the OS and eBPF support is compiled in, this allows to load a custom load-balancer. To load-share, daemons have to be part of the same cluster_name and each be configured with a distinct cluster_id.
• Introduced support for listening on VRF interfaces on Linux for all daemons. The feature can be enabled via nfacctd_interface, bgp_daemon_interface and equivalent knobs. Many thanks to Marcel Menzel ( @WRMSRwasTaken ) for this contribution.
• pre_tag_map: introduced limited tagging / labelling support for BGP (pmbgpd), BMP (pmbmpd), Streaming Telemetry (pmtelemetryd) daemons. ip, set_tag, set_label keys being currently supported.
• pre_tag_map: defined a new pre_tag_label_encode_as_map config knob to encode the output 'label' value as a map for JSON and Apache Avro encodings, ie. in JSON "label": { "key1": "value1", "key2": "value2" }. For keys and values to be correctly mapped, the '%' delimiter is used when composing a pre_tag_map, ie. "set_label=key1%value1,key2%value2 ip=0.0.0.0/0". Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution.
• pre_tag_map: introduced support for IP prefixes for src_net and dst_net keys for indexed maps (maps_index set to true). Indexing being an hash map, this feature currently tests data against all defined IP prefix lenghts in the map for a match (first defined matching prefix wins).
• pre_tag_map: introduced two new 'is_nsel', 'is_nel' keys to check for the presence of firewallEvent field (233) and natEvent field (230) in NetFlow/IPFIX respectively in order to infer whether data is NSEL / NEL. If set to 'true' this does match NSEL / NEL data, if set to 'false' it does match non NSEL / NEL data respectively.
• Introduced a new mpls_label_stack primitive, encoded as a string and includes a comma-separated list of integers (label values). Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution.
• Introduced a new fw_event primitive, to support NetFlow v9/ IPFIX firewallEvent 233 Information Element.
• Introduced a new tunnel_tcp_flags primitive for pmacctd and sfacctd to record TCP flags for the inner layer of a tunneled technology (ie. VXLAN). Also tunnel_dst_port decoding was fixed for sfacctd.
• Introduced support for in/out VLAN support for sfacctd. To be savy, 'in_vlan' and 'vlan' were muxed onto the same primitive depending on the daemon being used. Thanks to Jim Westfall ( @jwestfall69 ) for this contribution.
• Introduced a new mpls_label_stack_encode_as_array config knob to encode the MPLS label stack as an array for JSON and Apache Avro encodings, ie. in JSON "mpls_label_stack": [ "0-label0", "1-label1", "2-label2", "3-label3", "4-label4", "5-label5" ] and in Avro "name": "mpls_label_stack", "type": { "type": "array", "items": { "type": "string" } }. Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution.
• Introduced a new tcpflags_encode_as_array config knob to encode TCP flags as an array for JSON and Apache Avro, ie. in JSON "tcp_flags": [ "URG", "ACK", "PSH", "RST", "SYN", "FIN" ] and in Avro "name": "tcp_flags", "type": { "type": "array", "items": { "type": "string" } }. Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution.
• Introduced a new fwd_status_encode_as_string config knob to encode the 'fwd_status' primitive in human-readable format like described by RFC-7270 Section 4.12 when JSON or Avro formats are selected for output. Thanks to Salvatore Cuzzilla ( @scuzzilla ) for this contribution.
• Introduced a new protos_file to define a list of (known/ interesting/meaningful) IP protocols. Both protocol names, ie. "tcp", and protocol numbers, ie. 1 (for icmp), are accepted. IANA reserved protocol value 255 is used to bucket as 'others' those IP protocols not matching the ones defined in the list.
• Introduced a new tos_file to define a list of (meaningful) IP ToS values; if tos_encode_as_dscp is set to true then DSCP values are expected as part of the file. The directive uses value 255 to bucket as 'others' those ToS/DSCP values not matching the ones defined in the list.
• A new tos_encode_as_dscp config knob makes pmacct to honour only the 6 bits used by DSCP and report only on those.
• BGP, BMP, Streaming Telemetry daemons: introduced a new dump_time_slots config knob to spread the load deriving by dumps over the configured refresh time interval. The interval is divided into time slots and nodes are assigned to such slots. The slot for each node is determined using its IP address. Thanks to Raphael Barazzutti ( @rbarazzutti ) for this contribution.
• BGP, BMP daemons: End-of-RIB messages are now being exposed in the output feed in order to facilitate tracking their arrival (or not!).
• pmtelemetryd: aligned daemon to the latest Unyte UDP-Notif API (0.6.1) and related standardization draft-ietf-netconf-udp-notif
• RPKI daemon: added case for input "asn" value being integer (ie. "asn" : 2914) on top of the string case (ie. "asn" : "AS2914").
• Kafka, amqp plugins: introduced a new writer_id_string config knob to allow to customize the the "writer_id" field value. A few variables are supported along with static text definitions.
• Added a new aggregate_unknown_etype config knob to account also frames with EtherTypes for which there is no decoding support and allow to aggregate them by the available Ethernet L2 fields (ie. 'src_mac', 'dst_mac', 'vlan', 'cos', 'etype'). Thanks to @singularsyntax for this contribution.
• Added a new bgp_daemon_add_path_ignore config knob to ignore (do not advertise back) the ADD-PATH capability advertised by remote BGP peers.
• nfacctd, sfacctd: extended the possibility to run daemons from a user with non root privileges to these daemons.
• nfacctd: if Information Element 90 (MPLS VPN RD) is present in NetFlow v9/IPFIX, make it available for BGP/BMP correlation.
• pmacctd, sfacctd: introduced basic support for QinQ, 802.1AD.
• [print|kafka|amqp]_preprocess: added suppport for 'maxp', 'maxb' and 'maxf' keys when preprocessing aggregates of non- SQL plugins. Thanks to Andrew R. Lake ( @arlake228 ) for this contribution.
• nDPI: newer versions of the library (ie. >= 4.0) bring changes to the API. pmacct is now aligned to compile against these. At the same time support for nDPI 3.x was dropped.

• fix, plugin_common.[ch]: when stitching feature was enabled, ie. nfacctd_stitching, timestamp_min was never reset. Also both timestamp_min and timestamp_max were clamped to sec granularity.
• fix, BGP, BMP daemons: added a tmp_bgp_daemon_origin_type_int to print out BGP "origin" field as int (legacy behaviour) instead of string (current behaviour). In a future major release the legacy behaviour will be dropped.
• fix, BGP, BMP daemons: MPLS labels are now encoded in both JSON and Apache Avro as 'mpls_label' instead of 'label'. This is to align behaviour with pre_tag_map where 'label' has a different semantic.
• fix, BGP, BMP daemons: resolved memory leak when encoding log messaging (logmsg) in Avro format with Schema Registry support.
• fix, BGP daemon: improved handling of ADD-PATH capability, making it per-AF (as it is supposed to be) and not global.
• fix, BMP daemon: now checking that ADD-PATH capability is enabled at both ends of the monitored session (check both BGP OPEN in a Peer Up message) in order to infer that the capability exchange was successful. Also some heuristics were added to conciliate BGP Open vs BGP Update 4-bytes ASN reality.
• fix, nfacctd: improved parsing of NetFlow v9 Options data particularly when multiple IEs are packed as part of a flowset.
• fix, nfacctd: corrected parsing of Information Element 351 (layer2SegmentId).
• fix, pmacctd: improved processing of pcap_interfaces_map for cases where the same interface is present multiple times (maybe with different directions). Also, if the map is empty then bail out at startup.
• fix, pmacctd: SEGV when ICMP/ICMPv6 traffic was processed and 'flows' primitive was enabled.
• fix, pmacctd: sampling_rate primitive value was not reported correctly when 'sampling_rate' config directive was specified.
• fix, pmbgpd, pmpmbd, pmtelemtryd: changed SIGCHLD handler to prevent zombification of last spawned data dump writer.
• fix, Kafka plugin: moved the schema registration from the dump writer to the plugin process in order to register the schemas only once at plugin startup and not on every start of a writer process. Thanks to Uwe Storbeck ( @ustorbeck ) for this contribution.
• fix, Kafka plugin: a check for kafka_partition was missing, leading the plugin to always use the default partitioner instead of sending data to the configured fixed partition. Thanks to Martin Pels ( @rodecker ) for this contribution.
• fix, nfprobe plugin: BGP data enrichment was not working due to a mistakenly moved pointer.
• fix, sfprobe plugin: AS-PATH was being populated even when null; added a check to see if the destination AS is not zero in order to put the destination AS into the AS-PATH for sFlow packets. Thanks to Marcel Menzel ( @WRMSRwasTaken ) for this contribution.
• fix, networks_file: remove_dupes() was making partial commits of valid rows hence creating data inconsistencies.
• fix, pre_tag_map: resolved a potential string overflow that was being triggered in pretag_append_label() when data would be assigned more than one single label. Also now allow ',' chars in set_label.
• fix, maps_index: uninitialized var could cause SEGV in case no results are found in the map index. Also introduced support for catch-all rules, ie. "set_label=unknown".
• fix, maps_index: optimized the case of no 'ip' key specified (for nfacctd and sfacctd): when indexing is enabled, prevent recirculation from happening, ie. test v4 first then v6, since the 'ip' key is not going to be part of the hash serializer.
• fix, pretag.c: allow to allocate maps greater than 2GB in size. Also several optimizations were carried out yelding to a better memory utilization for allocated maps along with improved times to resolve JEQs.
• fix, pre_tag_label_filter: optimized and improved runtime evaluation part of this feature, avoiding a costly strdup() and returning immediately on certain basic mismatch conditions.
• fix, kafka_common.[ch]: a new p_kafka_produce_data_and_free() is invoked to optimize memory allocations and releases.
• fix, plugin_cmn_avro.c: when a schema registry is being defined, ie. kafka_avro_schema_registry, the logic to generate the schema name has been changed: use topic plus record name as the schema name, use underscore as separator within the record name, stop adding a "-value" suffix. Thanks to Uwe Storbeck ( @ustorbeck ) for this contribution.
• fix, util.c: roundoff_time() to reason always with the locally configured time, like for the rest of functional (as in non-data) timestamps, ie. refresh time, deadline, etc.
• fix, log.c: when log messages are longer than message buffer, the message gets cut off. As the trailing newline also gets cut off the message will be concatenated with the following message which makes the log hard to read. Thanks to Uwe Storbeck ( @ustorbeck ) for this contribution.

• Completed the retirement of legacy packet classification based on home-grown code (Shared Objects) and the L7 layer project.
• Removed the mpls_stck_depth primitive due to the introduction of the mpls_label_stack primitive.

• BGP, BMP, Streaming Telemetry daemons: introduced parallelization of dump events via a configurable amount of workers where the unit of parallelization is the exporter (BGP, BMP, telemetry exporter), ie. in a scenario where there are 4 workers and 4 exporters each worker is assigned one exporter data to dump.
• pmtelemetryd: added support for draft-ietf-netconf-udp-notif: a UDP-based notification mechanism to collect data from networking devices. A shim header is proposed to facilitate the data streaming directly from the publishing process on network processor of line cards to receivers. The objective is a lightweight approach to enable higher frequency and less performance impact on publisher and receiver process compared to already established notification mechanisms. Many thanks to Alex Huang Feng ( @ahuangfeng ) and the whole Unyte team.
• BGP, BMP, Streaming Telemetry daemons: now correctly honouring the supplied Kafka partition key for BGP, BMP and Telemetry msg logs and dump events.
• BGP, BMP daemons: a new "rd_origin" field is added to output log/ dump to specify the source of Route Distinguisher information (ie. flow vs BGP vs BMP).
• pre_tag_map: added ability to tag new NetFlow/IPFIX and sFlow sample_type types: "flow-ipv4", "flow-ipv6", "flow-mpls-ipv4" and "flow-mpls-ipv6". Also added a new "is_bi_flow" true/false key to tag (or exclude) NSEL bidirectional flows. Added as well a new "is_multicast" true/false config key to tag (or exclude) IPv4/IPv6 multicast destinations.
• maps_index: enables indexing of maps to increase lookup speeds on large maps and/or sustained lookup rates. The feature has been remplemented using stream-lined structures from libcdada. This is a major work that helps preventing the unpredictable behaviours caused by the homegrown map indexing mechanism. Many thanks to Marc Sune ( @msune ).
• maps_index: support for indexing src_net and dst_net keywords has been added.
• Added <daemon_name>_ipv6_only config directives to optionally enable the IPV6_V6ONLY socket option. Also changed the wrong setsockopt() IPV6_BINDV6ONLY id to IPV6_V6ONLY.
• Added log function to libserdes to debug transactions with the Schema Registry when kafka_avro_schema_registry is set.
• nDPI: newer versions of the library (ie. >= 3.5) bring changes to the API. pmacct is now aligned to compile against these.
• pmacctd: added pcap_arista_trailer_offset config directive since Arista has changed the structure of the trailer format in recent releases of EOS. Thanks to Jeremiah Millay ( @floatingstatic ) for his patch.
• More improvements carried out on the Continuous Integration (CI) side by migrating from Travis CI to GitHub Actions. Huge thanks to Marc Sune ( @msune ) to make all of this possible.
• More improvements also carried out in the space of the Docker images being created: optimized image size and a better layered pipeline. Thanks to Marc Sune ( @msune ) and Daniel Caballero ( @dcaba ) to make all of this possible.
• libcdada shipped with pmacct was upgraded to version 0.3.5. Many thanks Marc Sune ( @msune ) for his work with libcdada. ! build system: several improvements carried out in this area, ie. improved MySQL checks, introduced pcap-config tool for libpcap, compiling on BSD/old compilers, etc. Monumental thanks to Marc Sune ( @msune ) for his continued help. ! fix, nfacctd: improved euristics to support the case of flows with both IPv4 and IPv6 source / destination addresses (either or populated). Also improved euristics to distinguish event data vs traffic data in NetFlow v9/IPFIX from Cisco 9300/9500, ASA firewalls and Cisco 4500X. ! fix, nfacctd: improved support for initiatorOctets (IE #231) and responderOctets (IE #232). Thanks to Esben Laursen ( @hyberdk ) for reporting the issue. ! fix, nfacctd: in NF_mpls_vpn_id_handler() double ntohl() calls were applied for the case of 'vrfid'-encoded mpls_vpn_rd field. ! fix, sfacctd: wrong ethertype set for VLAN-tagged, MPLS-labelled IPv6 traffic. Impacting BGP resolution among others. Thanks to Jeremiah Millay ( @floatingstatic ) for his help resolving the problem. ! fix, BGP, BMP daemons: parsing improvements: added a check for BGP Open message and BGP Open Options lengths. Strengthened parsing of Peer Up, Route Monitoring and Peer Down v4 messages. ! fix, BGP, BMP daemon: when using Avro encoding and Avro Schema Registry, attempt to reconnect if serdes schemas are voided. Also now checking for serdes schema definitions before doing a serdes_schema_serialize_avro() to avoid triggering a SEGV. Finally improved serdes logging. ! fix, BGP, Streaming Telemetry daemons: in daemon logs, summary counters for amount of tables / entries dumped were wrong. ! fix, BGP daemon: distinguish among null and zero value AIGP and Prefix SID attributes. Same applies for Local Preference and MED attributes. ! fix, BMP daemon: resolved a memory leak in bgp_peers_free(). Thanks to Pether Pothier ( @pothier-peter ) for his patch. Also resolved a leak caused by an invalid BGP message contained in a BMP Route Message v4. ! fix, BMP daemon: correctly setting peer_ip and peer_tcp_port JSON fields for Term messages. Also the correct bmp_router value when bmp_daemon_parse_proxy_header feature is enabled. ! fix, BMP daemon: several encoding issues when using Apache Avro ie. u_int64_t now correctly encoded with avro_value_set_long(), certain u_int32_t fields switched to avro_value_set_long() due to lack of unsignedness in Avro encoding, improved various aspectes of Avro-JSON format output, etc. ! fix, pmtelemetryd: wrong parsing of pm_tfind() output was leading to mistaken data attribution of UDP-based peers (always first peer to connect was being picked). ! fix, pmtelemetryd: when set, the pidfile config directive was not being correctly honoured. ! fix, RPKI: the RTR PDU element for maxLength is uint8, therefore it might have been possible to transmit incorrect RTR data. Thanks to Job Snijders ( @job ) for his patch. ! fix, SQL plugins: amended the text composition of SQL queries that are involving latitude and longitude keys. ! fix, MySQL plugin: check for 'unix:' prefix string only when a sql_host configuration directive is specified. ! fix, nfprobe: modernized Application Information export. Until the previous release pmacct was adhering to aging NBAR model whereas now NBAR2 has been implemented. Thanks to Rob Cowart ( @robcowart ) for helping out resolving this issue. ! fix, tee plugin: restored usefulness of tee_source_ip which was broken in 1.7.6. Thanks to Jeremiah Millay ( @floatingstatic ) for reporting the issue. ! fix, maps_index: indexing of mpls_pw_id was broken. Also now, when the feature is enabled, actual data is being referenced in the index structure instead of creating a copy of it; thanks to Sander van Delden ( @SanderDelden ) for reporting the memory leak that was resulting from the copy. ! fix, kafka_common.c: solved memory leak in p_kafka_set_topic() when Kafka session was getting in down state. Many thanks to Peter Pothier ( @pothier-peter ) for nailing the issue. ! fix, net_aggr.[ch]: when a networks_file is specified in the config, gracefully handle max memory structure depth; added also de-duplication of entries. ! fix, pmacct-defines.h: if PCAP_NETMASK_UNKNOWN is not defined, ie. in libpcap < 1.1.0, let's define it. ! fix, SO_REUSEPORT feature was being restricted to Linux only in previous releases: now it has been unlocked to all other OS that do support the feature. ! fix, split SO_REUSEPORT and SO_REUSEADDR setsockopt() calls. Thanks to @eduarrrd for reporting and resolving the issue. ! fix, several code warnings catched gcc9 and clang.

• Obsoleted sql_history_since_epoch, pre_tag_map_entries and refresh_maps configuration directives.

• Added dependency to libcdada in an effort to streamline basic data structures needed for everyday coding. All new structures will make use of libcdada, old ones will be ported over time. Libcdada offers basic data structures in C: ie. list, set, map/ hash table, queue and is a libstdc++ wrapper. Many thanks to Marc Sune ( @msune ) for his work with libcdada and his enormous help facilitating the integration.
• BGP daemon: added suppport for Accumulated IGP Metric Attribute (AIGP) and Label-Index TLV of Prefix-SID Attribute.
• BGP daemon: added SO_KEEPALIVE TCP socket option (ie. to keep the sessions alive via a firewall / NAT kind of device). Thanks to Jared Mauch ( @jaredmauch ) for his patch.
• BGP daemon: if comparing source TCP ports among BGP peers is being enabled (config directive tmp_bgp_lookup_compare_ports), print also BGP Router-ID as distinguisher as part of log/dump output.
• BMP daemon: added support for HAProxy Proxy Protocol Header in the first BMP message in order to determine the original sender IP address and port. The new bmp_daemon_parse_proxy_header config directive enables the feature. Contribution is by Peter Pothier ( @pothier-peter ).
• BMP daemon: improved support and brought implementation on par with the latest drafting efforts at IETF wrt draft-cppy-grow-bmp- path-marking-tlv, draft-xu-grow-bmp-route-policy-attr-trace, draft-ietf-grow-bmp-tlv and draft-lucente-grow-bmp-tlv-ebit.
• BMP daemon: added 'bgp_agent_map' equivalent feature for BMP.
• nfacctd, nfprobe plugin: added support for collection and export of NetFlow/IPFIX data over Datagram Transport Layer Security (in short DTLS). The feature depends on the GnuTLS library.
• nfacctd: added support for deprecated NetFlow v9 IE #104 (layer2packetSectionData) as it is implemented for NetFlow-lite on Cisco devices. Reused code from IPFIX IE #315.
• nfacctd: added support for MPLS VPN RD IE #90. This comes in two flavours both found across vendor implementations: 1) IE present in flow data and 2) IE present in Options data as a lookup from IE #234 (ingressVRFID) and #235 (egressVRFID).
• nfacctd: added a new timestamp_export aggregation primitive to record the timestamp being carried in the header of NetFlow/IPFIX messates (that is, the time at which the export was performed).
• nfprobe plugin: added support for ICMP/ICMPv6 information as part of the NetFlow/IPFIX export. The piece of info is encoded in the destination port field as per the current common understandings across vendors. As a result of that, the 'dst_port' primitive is to be part of the aggregation method in order to leverage this feature.
• MySQL plugin: introduced support to connect to a MySQL server via UNIX sockets.
• tee plugin: added crc32 hash algorithm as a new balancing option for nodes in the receiving pool. It hashes original exporter IP address against a crc32 function. Thanks to @edge-intelligence for the contribution.
• Massive improvements carried out on the Continuous Integration (CI) side, ie. to ensure better quality of the code, and on the containerization side by offering official stable / bleeding edge Docker images. Huge thanks to Marc Sune ( @msune ) to make all of this possible.

• pmacct & Redis: pmacct daemons can now connect to a Redis cache. The main use-case currenly covered is: registering every stable daemon component in a table so to have, when running a cluster comprising several daemons / components, an olistic view of what is currently running and where; shall a component stop running or crash it will disappear from the inventory.
• BMP daemon: as part of the IETF 107 vHackaton, preliminar support for draft-xu-grow-bmp-route-policy-attr-trace and draft-lucente- grow-bmp-tlv-ebit was introduced. Also added support for Peer Distinguisher field in the BMP Per-Peer Header.
• BMP daemon: added support for reading from savefiles in libpcap format (pcap_savefile, pcap_savefile_delay, pcap_savefile_replay, pcap_filter) as an alternative to the use of bmp_play.py.
• BMP daemon: re-worked, improved and generalized support for TLVs at the end of BMP messages. In this context, unknown Stats data is handled as a generic TLV.
• BMP daemon: added SO_KEEPALIVE TCP socket option (ie. to keep the sessions alive via a firewall / NAT kind of device). Thanks to Jared Mauch ( @jaredmauch ) for his patch.
• nfacctd, nfprobe plugin: added usec timestamp resolution to IPFIX collector and export via IEs #154, #155. For export, this can be configured via the new nfprobe_tstamp_usec knob.
• nfacctd: new nfacctd_templates_receiver and nfacctd_templates_port config directives allow respectively to specify a destination where to copy NetFlow v9/IPFIX templates to and a port where to listen for templates from. If nfacctd_templates_receiver points to a replicator and the replicator exports to nfacctd_templates_port of a set of collectors then, for example, it gets possible to share templates among collectors in a cluster for the purpose of seamless scale-out.
• pmtelemetryd: in addition to existing TCP, UDP and ZeroMQ inputs, the daemon can now read Streaming Telemetry data in JSON format from a Kafka broker (telemetry_daemon_kafka_* config knobs).
• pmgrpcd.py: Use of multiple processes for the Kafka Avro exporter to leverage the potential of multi-core/processors architectures. Code is from Raphael P. Barazzutti ( @rbarazzutti ).
• pmgrpcd.py: added -F / --no-flatten command-line option to disable object flattening (default true for backward compatibility); also export to a Kafka broker for (flattened) JSON objects was added (in addition to existing export to ZeroMQ).
• nDPI: introduced support for nDPI 3.2 and dropped support for all earlier versions of the library due to changes to the API.
• Docker: embraced the technology for CI purposes; added a docker/ directory in the file distribution where Dockerfile and scripts to build pmacct and dependencies are shared. Thanks to Claudio Ortega ( @claudio-ortega ) for contributing his excellent work in the area.

• Released pmgrpcd.py v3: a Streaming Telemetry collector and decoder for multi-vendor environments written in Python3. It supports gRPC transport along with Protobuf encoding as input and can output to Kafka with Avro encoding. Output to files and JSON encoding is currently supported sending data via ZMQ to pmtelemetryd first. It was tested working with data input from Cisco and Huawei routers and v3 replaces v2. Thanks to the Streaming Telemetry core team: Matthias Arnold ( @tbearma1 ), Camilo Cardona ( @jccardonar ), Thomas Graf ( @graf3 , @graf3net ), Paolo Lucente ( @paololucente ).
• Introduced support for the 'vxlan' VXLAN/VNI primitive in all traffic daemons (NetFlow/IPFIX, sFlow and libpcap/ULOG). Existing inner tunnel primitives (ie. tunnel_src_host, tunnel_dst_host, tunnel_proto, etc.) have been wired to the VXLAN decoding and new ones (tunnel_src_mac, tunnel_dst_mac, tunnel_src_port, tunnel_dst_port) were defined.
• BMP daemon: added support for Peer Up message namespace for TLVs (draft-ietf-grow-bmp-peer-up) and also support for Route Monitor and Peer Down TLVs (draft-ietf-grow-bmp-tlv).
• BGP, BMP daemons: in addition to existing JSON export, data can now be exported in Apache Avro format. There is also support for the Confluent Schema Registry.
• Introduced support for JSON-encoded Apache Avro encoding. While the binary-encoded Apache Avro is always recommended for any production scenarios (also to optionallly leverage Confluent Schema Registry support), JSON-encoded is powerful for testing and troubleshooting scenarios.
• sfprobe plugin: added support for IPv6 transport for sFlow export. sfprobe_agentip is an IP address put in the header of the sFlow packet. If underlying transport is IPv6, this must be configured to an IPv6 address.
• zmq_common.[ch]: Improved modularity of the ZMQ internal API and decoupled bind/connect from push/pull and pub/sub; also improved support for inproc sockets. All to increase the amount of use-cases covered by the API.
• bgp_peer_src_as_map: added 'filter' key to cover pmacctd/uacctd use cases.
• nfprobe, sfprobe plugins: introduced [sn]fprobe_index_override to override ifindexes dynamically determined (ie. by NFLOG) with values computed by [sn]fprobe_ifindex.
• MySQL, PostgreSQL plugins: added support for SSL/TLS connections by specifying a CA certificate (sql_conn_ca_file).
• Kafka, AMQP plugins: amqp_markers and kafka_markers have now been properly re-implemented when output encoding is Avro using an own Avro schema (instead of squatting pieces of JSON in the data stream for the very purpose).
• print plugin: introduced print_write_empty_file config knob (true, false) to create an empty output file when there are no cache entries to purge. Such behaviour was present in versions up to 0.14 and may be preferred by some to the new >= 1.5 versions behaviour. Thanks to Lee Yongjae ( @setup74 ) for the contribution.

• Introduced the RPKI daemon to build a ROA database and check prefixes validation status and coverages. Resource Public Key Infrastructure (RPKI) is a specialized public key infrastructure (PKI) framework designed to secure the Internet routing. RPKI uses certificates to allow Local Internet Registries (LIRs) to list the Internet number resources they hold. These attestations are called Route Origination Authorizations (ROAs). ROA information can be acquired in one of the two following ways: 1) importing it using the rpki_roas_file config directive from a file in the RIPE Validator format or 2) connecting to a RPKI RTR Cache for live ROA updates; the cache IP address/port being defined by the rpki_rtr_cache config directive (and a few more optional rpki_rtr_* directives are available and can be reviwed in the CONFIG-KEYS doc). The ROA fields will be populated with one of these five values: 'u' Unknown, 'v' Valid, 'i' Invalid no overlaps, 'V' Invalid with a covering Valid prefix, 'U' Invalid with a covering Unknown prefix. Thanks to Job Snijders ( @job ) for his support and vision.
• Introducing pmgrpcd.py, written in Python, a daemon to handle gRPC- based Streaming Telemetry sessions and unmarshall GPB data. Code was mostly courtesy by Matthias Arnold ( @tbearma1 ). This is in addition (or feeding into) pmtelemetryd, written in C, a daemon to handle TCP/UDP-based Streaming Telemetry sessions with JSON-encoded data. Thanks to Matthias Arnold ( @tbearma1 ) and Thomas Graf for their support and contributing code.
• pmacctd, uacctd: added support for CFP (Cisco FabricPath) and Cisco Virtual Network Tag protocols. Both patches were courtesy by Stephen Clark ( @sclark46 ).
• print plugin: added 'custom' to print_output. This is to cover two main use-cases: 1) use JSON or Avro encodings but fix the format of the messages in a custom way and 2) use a different encoding than JSON or Avro. See also example in examples/custom and new directives print_output_custom_lib and print_output_custom_cfg_file. The patch was courtesy by Edge Intelligence ( @edge-intelligence ).
• Introducing mpls_pw_id aggregation primitive and mpls_pw_id key in pre_tag_map to filter on signalled L2 MPLS VPN Pseudowire IDs.
• BGP daemon: added bgp_disable_router_id knob to enable/disable BGP Router-ID check, both at BGP OPEN time and BGP lookup. Useful, for example, in scenarios with split BGP v4/v6 AFs over v4/v6 transports.
• BGP, BMP daemons: translate origin attribute numeric value into IGP (i), EGP (e) and Incomplete (u) strings.
• plugins: added new plugin_exit_any feature to make the daemon bail out if any (not all, which is the default behaviour) of the plugins exits.
• maps_index: improved selection of buckets for index hash structure by picking the closest prime number to the double of the entries of the map to be indexed in order to achieve better elements dispersion and hence better performances.
• nfacctd: added support for IPFIX templateId-scoped (IE 145) sampling information.
• pmacctd, uacctd, sfacctd, nfacctd: added a -M command-line option to set *_markers (ie. print_markers) to true and fixed -A command-line option to set print_output_file_append to align to true/false.
