Release notes 2020

The new service release comes with various changes, as for example:

New - Enrichment of events and messages
Subscribers of events and messages may request that the payload they receive is enriched with data from the related digital twin.
This way, you can add e.g. attributes or feature properties of your things, which are not included in the original payload, but are helpful for your consumers.
The selection of information to be added is defined using the parameter extraFields, which could point to one or multiple JSON fields of the things. Find details at Enrichment of events and messages.
Bosch IoT Things - various deprecations.
The deprecated parts are still supported. As soon as we drop support we will announce it here.
- API 1 is deprecated
  In case you start your implementation from scratch please use API 2 only.
  Applications using API 1 can find migration instructions at Migration from API 1 to API 2.
- The things-client is deprecated
  Please use the ditto-client instead. Find details at Developer guide > Java API
  Further, find an example on how to Migrate from things-client to ditto-client .
- The authentication via cryptographic challenge is deprecated
  The process to authenticate as a technical client via a public/private key pair is deprecated.
  Please use the OAuth authentication instead. Find details at Authenticate as a technical client.

At this occasion, various minor bugs have also been fixed.

The new service release comes with various changes, as for example:

New header named ditto-originator for internal use within Bosch IoT Things service.
It contains the first authorization subject of the command that caused the sending of this message.
See Developer guide > … > Protocol - specification > Headers.
Bosch IoT Things supports you in registering OAuth2 clients for your solution
Register clients for your solution via API PUT /solutions/{solutionId}/clients
See Create or update all authorized Clients of a specific Solution.
These clients will henceforth be authorized to make requests in the context of your solution. Thus, you will not need to send your API token on each request.
By now we support: Suite Auth, Bosch ID, Google, and custom OAuth2 providers upon request.
Refined the set of restrictions for identifiers:
- Only the slash character (/) and control characters need to be avoided in general.
- See Restrictions > Identifier
- See Restrictions > Decoding and encoding of special characters

At this occasion, various minor bugs have also been fixed.

Our first service release in 2020 comes with this change:

Chart view in Things Dashboard
The Things Dashboard includes a chart view for viewing Thing property data collected over the time. This view helps to understand IoT device sensor data during the development of IoT solutions. The shown data is live data updated in Thing properties and is only collected during the time when the dashboard view is open. The data series is not stored.
To open the view, go to the Things Dashboard into the Things list and click on a Thing entry. In the Thing view you can choose to switch to the chart view.
