V1.8.23

• Fix LACP flooding corner cases
• Fix setting useless pop_vlan action where all tagged ports on a VLAN are down
• Workaround LACP packets have appended nuls.
• Configurable workaround for OFA not resetting idle timer on rule refresh (idle_dst)
• Configurable workaround for OFA not sending packet out to all listed ports (multi_out)
• Faster learning for proactive learning (learn connected source host)
• More config-time checks for L2/L3 learning timers.

V1.8.22

• Experimental LACP active support (set lacp_active: True on ports with lacp enabled) - supported only to another FAUCET currently.
• FAUCET could occasionally falsely detect that a config change had occurred due to dict ordering.
• Experimental infrastructure for OpenFlow metadata and output ACL tables (not complete yet)
• Stricter length checks for control plane (and fix ICMPv4 echo not replied to)
• When multi_out: False set disable multiple outputs in packet out message.

v1.8.21

• Don't refresh eth_dst rules if a non-hairpinned host didn't move ports (reduced maintenance flowmods)
• Implement Generic hardware type (relative table IDs, no TFM, barriers)
• Decreased L2 cache updates (reduced maintenance flowmods)
• Controller flood requests use same packet with multiple output ports (reduced packet outs for nexthop resolution)
• Avoid unnecessary regeneration of Prometheus learned_macs.
• Add Prometheus variable faucet_service_secs for background services runtime.
• Upgrade docker base image to alpine 3.8.1

V1.8.20

• Routing supports clients on same port in different VLANs (w/hairpin_unicast: True). Uses new eth_dst_hairpin table.
• Fix table next_table and set_fields properties not verified.
• Experimental 802.1x RADIUS and multi port/DP support.

V1.8.19

Rollback Chewie.

V1.8.18

• First retry of stale IP nexthop is unicasted, to satisfy neighbor reachability
• Fix Gauge crash where multiple DPs that have different table layouts
• Fix non-unicast traffic forwarded muliply on LACP bundles
• TFM next tables decided from pipeline config
• TFM autosizer permits more scale tests to pass
• RADIUS support for 802.1x

V1.8.17

• Fix if more than one DP, could send wrong TFM.
• dp_status incorrectly set to 0 on config reload.
• More aggressive nexthop resolver (to clear dead nexthops).
• All packet outs order randomized.
• Experimental support for MD5 802.1x on one port.
• python3 mininet.
• NoviFlow recommended hardware now GenericTFM.
• Add Zodiac GX

V1.8.16

• Correct broken apt packages which broke VM image and Raspbian image
• Improve performance of IPv4/IPv6 nexthop resolver
• Fix crash on bad ICMPv6 packet

V1.8.15

• Improve table auto sizing for TFM switches
• Avoid sending multiple miss flows which might be reordered unintentionally
• Avoid unnecessary Ethernet header re-parsing
• Stacking edge switches have faster learning if directly connected to root

V1.8.14

• Enable global routing (if one router only is defined, and dp/global_vlan is set to an unused VID, router will use that VID for all routed VLANs so that FIB scales linearly)
• Fix incorrect use of class attributes that could cause objects (like ports) to have incorrectly entangled attributes (like port up status)
• Fix LACP port status Prometheus variable.
• Fix sending DEC_TTL action for TFM switches that support it.
