 - The POST /api/admin/makeDataCount/{id}/updateCitationsForDataset processing is now asynchronous and the response no longer includes the number of citations. The response can be OK if the request is queued or 503 if the queue is full (default queue size is 1000).
 - The way to set per-format size limits for tabular ingest has changed. JSON input is now used. See :ref:`:TabularIngestSizeLimit`.
 - In the past, the settings API would accept any key and value. This is no longer the case because validation has been added. See :ref:`settings_put_single`, for example.
+- For GET /api/notifications/all the JSON response has changed breaking the backward compatibility of the API.
