V1.7.1

• Enable send barrier after TFM, and send set_config/set_async early.
• Change combinatorial_port_flood default to False (depend on OF spec behavior to not send out input port unless requested with reserved port)
• Add FAUCET for the first time tutorial
• Add notify event for port status at DP connection time

V1.7.0

Upgrading to this release may require manual steps, check the release notes for more details.

• Package faucet/gauge for debian & ubuntu
• Start using new directories for config and logs
• Fix crash clearing cache on port with permanent_learn: True
• Fix duplicate flow/group adds/deletes
• Fix port mirroring of broadcasts to port
• Increase parsing performance (switch to YAML CLoader)
• Make combinatorial_port_flood configurable, default True but will switch to False in next release for fewer OF rules (L3 not yet supported)
• Add force_port_vlan option in ACL rules to force packet into a different FAUCET VLAN (requires combinatorial_port_flood: False)
• Add port override_output_port: n to force traffic from a port to a static port while still supporting MAC learning
• Disable barriers for OVS (less OF messages, OVS doesn’t use them anyway)

V1.6.27

Test base image build can fail, because pip doesn't reliably install setuptools before ryu.

V1.6.26

• Ryu 4.23
• Synchronize Prometheus DP port status when DP connects
• Fix extraneous broadcasts to controller when stacking (and don't learn broadcast sources from core to edge, reducing edge switch flow table sizes)
• FAUCET can send/receive LLDP packets with OUI TLV describing DP ID (for cabling/link verification)
• Log L3 dest address (if any) when learning
• Learning scale improvements (test up to 4096 hosts/switch)
• ACL output can do multiple ports
• Test meters with OVS

V1.6.25

• Fix learned host reporting/counting (bug introduced in 1.6.24)
• Fix dead L3 neighbors not being expired
• Workaround for stale netns in hairpin int. test
• Re-add bgp_connect_mode config option (e.g. peer can be set passive)
• Explicitly decode of_dp_desc_stats labels as UTF8.

V1.6.24

• DO NOT USE 1.6.24 (see 1.6.25 release notes)
• Upgrade to OVS 2.9.0 and DPDK 18.02
• Increase L2 and L3 scale baseline to 1024 and 2048 hosts respectively (many reductions to packet in processing, state expiry, and Prometheus export costs)
• Gauge logs port max/speed changes
• Rabbit MQ support for Pi
• Fix incorrect use of thread for Prometheus client (caused occasional data truncation)
• Gauge no longer needs empty prometheus_addr.
• Fix stacking config changes not being processed via cold start.

V1.6.23

• Remove CouchDB support
• Minor optimizations in L3 resolution path
• Don't configure flow removed notifications if not required
• LACP packets could be truncated
• Don't use OFPP_LOCAL port for test

V1.6.22

• Increase test coverage to 75% and enable code coverage reporting (https://codecov.io/gh/faucetsdn/faucet)
• Move FAUCET pipeline config to own file (faucet_pipeline.py)

V1.6.21

• Tests: Add coveralls test coverage reports to project
• Tests: Improve unit test coverage to 73%
• Enhancement: Refactor Ryu code into a new RyuApp class
• Enhancement: Add --display-labels option to fctl

V1.6.20

• Ryu 4.22
• Fix more bugs with stacked and non-stacked DPs under same controller.
• Interface mirrors can mirror more than one interface
• Can now configure multiple ACLs on same interface/VLAN
• Fix crash with status message from unknown port
• Fix port name references in ACLs for mirror ports
• Fix permanent drop of dead nexthop
• Increase unit test coverage to 72%
