LGTM

LGTM, but the changelog entry is now for the wrong version.

OK, I've rebased with the latestmaster and put the changelog entry in the 1.0 section.

I'm currently implementing a new "JSON provider" interface for customizing how an app handles JSON. As part of that, I'm deprecating theapp.config["JSONIFY_MIMETYPE"] parameter in favor of settingapp.json.mimetype (along with some other config that makes more sense as provider setup).

However, reviewing this I'm not clear that setting the mimetype unconditionally is correct. The JSON API mimetype seems to be specifically for responses related to its own metadata and introspection, not to the actual API responses. It makes much more sense to me to set the content type for the specific responses that need it:

response=jsonify(data)response.mimetype="application/vnd.api+json"returnresponse

Am I missing something here or can I remove the configuration entirely? Note that it would still be possible to change the default using a custom provider:

classVndProvider(DefaultJSONProvider):defresponse(self,*args,**kwargs):response=super().response(*args,**kwargs)response.mimetype="application/vnd.cool-api.v1+json"returnresponseapp.json=VndProvider(app)
