New features

  • Hono now supports using Google Pub/Sub as the messaging infrastructure. The Admin Guide and the API documentation have
    been amended with corresponding information on how to configure Hono and applications for using Pub/Sub.
  • Hono's MQTT and HTTP adapters now support using JSON Web Tokens (JWT) for authentication. In particular, the adapters
    allow devices that have been connected to Google's IoT Core endpoints to connect to Hono instead. The User Guides have
    been amended with corresponding information regarding configuration and usage.
  • The CoAP adapter now allows clients to retrieve the CoAP adapter's current time by means of including a query parameter
    and/or request option.
  • The HTTP protocol adapter now supports authenticating devices using the JWT based authentication scheme employed by
    Google IoT Core.
  • The command router now has experimental support for routing commands received via Google Pub/Sub to connected devices.
  • The authentication identifier being created for devices that are using client certificate based auto-provisioning can now
    be specified as a pattern based on fields from the certificate's subject DN.

Fixes & Enhancements

  • The JDBC based device registry now supports searching for tenants and devices including paging. However, sorting is not
    implemented (yet) and the number of filter predicates is (currently) limited to one.
  • The MQTT adapter failed to close a connection with a client after the JWT used by the client for authentication had expired.
    This has been fixed.
  • Hono could not be built using Maven 3.9.0 and newer. This has been fixed.
