--- fixes: - This fix binds the jsonschema to use draft-04 for raid schema. The jsonschema 3.0.1 supports draft-03, draft-04, draft-06 and draft-07 and by default the validate function uses latest draft validator. Draft-04 is the latest draft in the jsonschema 2.6. Hence binding the schema to draft-04 validator makes it compliant for both jsonschema 2.6 and jsonschema 3.0.1.
