Changes

• The ._links field, which contained non-user-relevant Mailchimp metadata, has been removed from all streams.
• All instances of datetime fields have had their type changed from string to airbyte-type timestamp-with-timezone. This change should ensure greater precision and consistency in how datetime information is represented and processed by destinations.
• The Mailchimp API returns many fields without data as empty strings. To accomodate the above changes, empty strings are now converted to null values:

{"id": "record_id", "last_opened": ""} -> {"id": "record_id", "last_opened": null}
