Varnish Controller 6.6.4 Release

Note: We recommend updating all components for this patch release, as they all include fixes. See: versioning.

• Support for Prometheus 3.x (api-gw now uses content-type tex/plain for Prometheus calls)
• Fixes a bug in the Router when fetching debug information.
• Brainz will now warn for expiring license on stdout 30 days before it expires (previous 10 days before).
• Set From now shows correctly File for configuration that comes from file and was specified in the global scope of the configuration file.
• Fixed a bug where UI log in would crash.

See Varnish Controller Changelog for more details on the changes and the upgrade notes for more details on how to upgrade.
