:wave: :robot: :thinking: Hello, @christinaausley! Did you make your changes in all the right places?

These files were changed only in docs/. You might want to duplicate these changes in versioned_docs/version-8.6/.

docs/components/modeler/bpmn/bpmn-coverage.md

You may have done this intentionally, but we wanted to point it out in case you didn't. You can read more about the versioning within our docs in our documentation guidelines.

@korthout thanks for sharing your opinion.

@saig0 @nikku could you support us here to define what would be needed so that we can claim we support Data store and data object elements?

TLDR: Data stores, input and output have always been modeling only from Camunda's perspective, in C8 and C7. We don't support any of the "data features" beyond modeling (for documentation purposes) that the BPMN standard defines.

BPMN implements data on two layers:

Visual, i.e. data stores and data objects, documentation only
For execution (+visual) using IO mappings (data input, and data output)

The later one is a direct competition to our own data mappings (both C7 and C8).

An answer to our users could be to mark them as supported (*) with the disclaimer that this includes "modeling only/for documentation" and that we do not support IO-mappings as defined in the BPMN standard.

From the spec:
