 Note that 'generic' changes apply to `type` application, dataset and notebook of the same `format_versions`.
 If the changes also apply to `type` model, the coresponding model format version is noted, e.g. [generic 0.3.1 and model 0.5.3](#generic-031-and-model-053).
 
+#### model 0.5.6

+- Non-breaking changes:
+  - New optional `weights.onnx.external_data` field to allow for (large) ONNX models split into an architecture and an external data (weights) file.
