Varnish Controller 6.6.0 Release

Note: All components needs to be upgraded for this release, see versioning.

• Support for Roles. This feature offers a structured approach to combining and managing permissions across multiple users.
• Resolved an issue where removing a tag from an agent incorrectly returned a 500 Internal Server Error instead of the actual error reason.
• Fixed an issue where the CLI override flag for configs displayed an incorrect long value.
• Addressed a problem where statistics aggregation caused unnecessary growth in the WAL log.
• Updated agent state changes in logs to display as text values for better clarity.
• Removed the duration field from the router’s request-log.
• Updated the basic invalidation lock acquisition error message to a debug-level log, providing clearer context and reducing unnecessary noise.
• UI: Major overhaul which has lead to several improvements in workflows and a performance boost.

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

This update is recommended for all users.
