Dear Hono Devs, Having also eagerly awaited the Command & Control functionality in Hono, we have given it a try and evaluated it in the context of the Bosch IoT Hub. New concepts
and APIs are easy to understand and we have had no problems integrating the functionality into the Hub services. We are currently using the feature in our tests to send commands to simulated devices. Here are a few feedback points * TTD is in seconds. It can be the case that this will not be "fine-grained" enough for all use cases. In other words, perhaps it would make sense to allow providing
the TTD in milliseconds. * If a device sets the TTD and there is no command to be sent from an application or applications, the response will be delayed. This seems to be an use case
which was not (yet) addressed or thoroughly thought through, although there is already a hono-dev email discussion on this topic. * It will be interesting to see how will Hono support the gateway mode in combination with the Command & Control functionality. In summary, using C&C was a smooth experience so far. We are looking forward to next releases of Hono and further features around Command & Control. Mit freundlichen Grüßen / Best regards

Im Auftrag von Hudalla Kai (INST/ECS4) Dear Hono community, This release introduces a technology preview of the long anticipated Command & Control functionality which can be used to send commands from back end applications to devices connected
to Hono. In this initial version it is possible to send commands to devices that connect to the HTTP protocol adapter only. In a future release we will add support for command & control to the MQTT adapter as well. We encourage users to start playing around
and evaluating the feature but would not recommend using it for production scenarios yet because we might need to make some changes to the API and/or implementation in the upcoming milestones and release. In any case, we are very interested in getting some
feedback regarding its usefulness and/or usability. Another interesting new feature is the support for authenticating devices using a client X.509 certificate. The device certificates are validated during connection establishment
based on a trust anchor that can be configured per tenant. Again, this feature is available in the HTTP adapter only for the time being. We will bring this feature to the MQTT adapter as soon as the Vert.x MQTT framework that we use in the MQTT adapter provides
access to the client certificate chain. Hono can be downloaded from the project website [1], individual artifacts are also available from the Eclipse Repository [2] and (later during the day)
from Maven Central [3]. More details regarding the new features and changes can be found in the release notes [6]. Finally, an outlook on future plans for Hono can be found in the Road Map [7]. [6]
