  • Fixed inaccurate error rate data for monitoring topology services.
  • Fixed returning 404 error when mesh does not exist.
  • Fixed panic caused by nil pointer in Audit.
  • Fixed displaying Enum type resource types as numbers in audit logs.
  • Fixed inconsistency in behavior between GRPC requests with user authentication information and HTTP requests.
  • Fixed failure to create Telemetry resources during dedicated mesh creation.
