Doesn't look like any of that impacts CB Connect. The API endpoints CB Connect is using have not been deprecated and their usage is consistent with their documentation. They do have a new endpoint for reaching profile data, but the existing endpoint for reaching profile data appears to be still valid.
Looks like they're just changing how you create an Instagram application and how they handle permissions review for your application. CB Connect can already handle cases of the user not wanting to share partial information (e.g. if they don't want to share email address CB Connect will ask them for one). CB Connect actually only needs their social provider id to function, which can't be blocked via permissions.
At any rate have added a feature ticket to further review if our profile data API endpoint needs to be changed.
