1.9.1

Fixes & Enhancements

• The Quarkus based variants of Hono's components now support configuring the Hot Rod client with a key and/or
  trust store in order to enable TLS secured connections to Infinispan servers and to authenticate using a
  client certificate.
• The MongoDB based DeviceManagementService erroneously removed the original device registration when trying to
  register a new device using the existing device's identifier. This has been fixed.
• The Mongo DB based registry implementation now uses a proper DB index to find credentials by type and authentication
  ID. This will speed up query execution significantly when there are a lot of devices registered for a tenant.
• The JDBC based device registry's get Credentials operation used by the protocol adapters now also supports
  matching credentials against a given client context.
• The device registry implementations did not return a JSON object in a response to a failed request as specified
  in the Device Registry Management API. This has been fixed.
• The tracing output in error scenarios has been improved in the Mongo DB based device registry.
• The MongoDB based registry erroneously rejected requests that would result in multiple tenants having an empty
  set of trusted CAs. This has been fixed.
