1.8.1

Fixes & Enhancements

• Letting the trace sampling settings of the Hono components be defined via sampling strategies served by the Jaeger
  Collector did not work for components using Quarkus native images. This has been fixed.
• Command messages with no payload could not be sent to an MQTT device. This has been fixed.
• The value of the properties auto-provisioned and auto-provisioning-notification-sent are always false while
  retrieving device registration information using the MongoDB based registry implementation. This has been fixed now.
• The Command Router service could have gotten into a state of very high CPU utilization when protocol
  adapters submitted non-existing tenant IDs for which command routing should be re-enabled. This has been fixed.
• The LoRA protocol adapter will now free command consumer resources when the idle timeout of the corresponding tenant
  (configured via the hono.lora.tenantIdleTimeout property) has elapsed and the tenant is already removed or disabled.
• The device registry implementations have already supported the limitation of the body size of requests to the
  /tenants and /credentials resources of the HTTP based Device Registration Management API.
  However, the admin guides did not cover the corresponding HONO_REGISTRY_HTTP_MAXPAYLOADSIZE configuration variable
  yet. The /devices resources have been added to the scope of the feature and the admin guides have been amended
  accordingly.
