V1.9.24

• Add fakeoftable.py browser (can trace packets through a JSON dumped flow table)
• Add port.collect_and_distribute option (to set both flags when LACP is up)
• Rename lacp_status prometheus metric to lacp_state which exposes more information
• Separate stack port state for incorrect cabling
• Add stack change events

• Fix handling of bad initial config file if auto revert is enabled
• Fix should not be able to configure host prefix (/32) as VIP
• Fix LLDP max lost parameter was not configurable
• Fix tunnel ACL could not be applied to multiple ports
• Fix could not configure a switch in a stack that only had stack ports (no local VLANs expressed)
• Fix root switch in stack with no healthy stack links was considered healthy

V1.9.22

• New stacking tutorials
• Allow tuning of TFM autosizer (port_table_scale_factor), fix override of table sizes.
• Handle a non-reflected stack degraded to a string
• Fix test for LACP passthrough
• Relax timers for DPs that do not support idle/hard timers < 10s

V1.9.21

• Fix and test stack rings (multiple paths of same length)
• Support coprocessor ports (can inject packets into pipeline or do DP packet out)
• Fix ACL meters not deleted on cold start
• Stricter checking of configuration file for potential issues (mismatched features etc)

V1.9.18

• FAUCET should not learn all-zeros eth src.
• FAUCET should keep cache on warm started ports and VLANs
• Gauge can detect a changed FAUCET config and reload config

V1.9.17

L2 stack and failover reliability fixes.
