 - Removes `with_carbon_offset` parameter from `create`, `buy` and `regenerate_rates` methods in the shipment service since now EasyPost offers carbon neutral shipments by default for free
 - Fixes a bug where the original filtering criteria of `all` calls wasn't passed along to `get_next_page` calls. Now, these are persisted via `_params` key on response objects
 - Removes the undocumented `create_and_buy` function from the Batch service. The proper usage is to create a batch first and buy it separately

+## 7.0 Error Parsing
+
+*Likelihood of Impact: **High***
+
+The `errors` key of an error response can return either a list of `FieldError` objects or a list of strings. The error parsing has been expanded to include both formats. As such, you will now need to check for the format of the `errors` field and handle the errors appropriately for the type that is returned.
+
+The `Error` model has been removed since it is unused and we directly assign properties of an error response to the `ApiError` type.
+
+The `code` and `field` properties of an `EasyPostError` have been removed as they only belong to the `ApiError` type.
+
+## 7.0 Deprecations
+
+*Likelihood of Impact: **Medium***
+
+The following deprecated functions have been removed:
+
+- `tracker.create_list` (trackers must be created individually moving forward)
+- `user.all_api_keys` (use `api_key.all`)
+- `user.api_keys` (use `api_key.retrieve_api_keys_for_user`)
+
+The `irb` has been removed from this library.
+
 ## Upgrading from 5.x to 6.0
 
+**NOTICE:** v6 is deprecated.
