 - `POST /api/card` and `PUT /api/card/:id`
 
-  The `dataset` key is deprecated and will be removed in a future version, most likely 50. In its place we have added a new key: `type` which is equivalent in that it distinguishes Models from Questions. `type="model"` is equivalent to `dataset=true` and `type="question"` is equivalent to `dataset=false`.
