Release Notes

Improvements

• Data plane improvements.

Improvements

New features:

• Dynamic multicast: operators can join and leave streams on demand. It is off by default and turned on per node, with a join/leave drawer in the UI.

• Multicast admission policy: allow and block rules, a catch-all default rule, a first-time setup flow, and blocking of specific sources.

• Fleet management: fleet rollup, membership claim and release, a "managed-by" setting, and a break-glass override. Peers keep their identity across endpoint changes, and users can now set an alias, location and display position for each node.

• Doctor diagnostics: packet capture, a WAN gateway check, a multicast membership view and memory checks.

• Network: separate MTU settings for WAN and LAN, kernel tuning, a network refresh command, and support for IPv6 sources.

Changed:

• API path renamed: /api/v1/peers/* is now /api/v1/groundswxtches/*.

• Management port: the default changed from 8080 to 80, and the metrics_enabled setting was removed.

Improvements

• Default and automatic handling of hugepages when deploying with the install script.

• Improved flushing of packets in the delay buffer once the assigned delay buffer size is exceeded.

• Fixed edge rendering: in some conditions, traffic was flowing but no edge was rendered.

• Separate MTU configuration for the WAN and LAN interfaces.

Improvements

• Improved handling of edge cases in the lossless protocol to ensure packets are not dropped.

Known issues

• If the groundSwXtch details pane is minimized and then maximized, adding a destination by selecting it from the drop-down list closes the user interface without adding it. To work around this, type the destination instead of using the drop-down.
