+## [2.0.0] - revision 2023-01-24
 
 - Added the following endpoints (which were previously in our Beta API/SDKs):
   - Data Privacy
   - All Tags endpoints, as well as the following related resource-specific endpoints:
     - Get Flow Tags
     - Get List Tags
     - Get Segment Tags
-- Reworked the response object returned by SDK methods
+- Reworked the response object from returned by SDK methods
   - instead of only returning the response payload, the status code and headers are now also returned
   - The API response payload is now nested under `body` within the API response returned by SDK methods. You can get the `id` of the returned resource by calling `response.body.data.id` instead of `response.data.id` from previous releases. You can get response headers and status with `response.headers` and `response.status` respectively.
