Release notes

Noteworthy new features and improvements in this release include:

• (#4122, #4131, #4156, and more) Cumulus is now ready for analysis with EVPN-based VXLANs! Please try it out and share your experience with us on Slack.
• (#4074, #4092, #4154) vxlanVniProperties and edges (and protocol-specific variants like bgpEdges) questions now include dynamic network state rather than just the configured topology by default. This is a breaking change to in response to user confusion.
• (#4101) Palo Alto Networks: Support next-vr references in static routes.

Bug fixes:

• (#4125) General: Fix crash related to aggregate interfaces with no children (thanks @Vadims06!).
• (#4169) Juniper: Fix handling of from tag in policy statement (thanks @Volcanon-!).
• (#4168) Juniper: Fix crash related to from metric in policy statement (thanks @Volcanon-!).
• (#4163) IOS-XR: Fix handling for done route policy disposition.

Breaking changes:

• See the note above about vxlanVniProperties and edges questions.

Release notes

Noteworthy new features and improvements in this release include:

• (#3883, #3823, #3835) Batfish now has initial VXLAN support, beginning with support for Cumulus and Arista devices.
  • switchedVlanProperties reports the VNI if any configured for each VLAN.
  • vxlanVniProperties reports the VNI-level network segment settings configured for VXLANs.
  • edges supports edgeType="VXLAN".
  • Batfish verifies VTEP reachability before establishing VXLAN tunnels.

Bug fixes:

• (#3907) Cisco: Correctly compute interface bandwidths for Port-Channel interfaces and subinterfaces.
• (#3886, #3877, #3873, and many more) Dataplane: Misc. performance improvements.

Breaking changes:

• (#3840) Batfish no longer supports expressing Layer-3 link failures by providing an edge_blacklist file. Users are recommended to blacklist interfaces instead, as in the example with outage network. Please file an issue if interface blacklists are not sufficient for your use case.
