1.8.2

Fixes & Enhancements

• The MQTT adapter didn't close the CONNECT tracing span and didn't report metrics on failed connection attempts. This
  has been fixed.
• The registry implementations failed to reject a request to update a device's empty set of credentials, e.g. right
  after the device has been created, if the request contained a secret having an ID. In fact, the registry
  implementations would have accepted such a request even if the secrets did not contain a password/key/etc at all
  but only the identifier. This has been fixed.
• A potential issue processing Command & Control messages from a Kafka cluster while Command Router instances are
  getting stopped or started has been fixed.
