Use case configuration no longer supports constants, lookups, params_mapping, required_params, file_source, fan_out.split_expression, upload.external_id, and upload.success_when — these fields are no longer accepted when creating or updating a use case or an integration, and are no longer returned by the use case, integration, and use case history endpoints (breaking)
Request steps of a use case gained two new optional fields: body_jsonata for building the request body with a JSONata expression, and enabled for switching a single step off; file uploads additionally accept an optional upload.max_total_bytes limit
POST /v2/erp/imports now accepts an optional import_id to continue working on an existing import, answers with 200 in that case, and can answer with 404 or 409 when the referenced import cannot be used
