 ## Improved
 
 ## Changed
+- For 3DS2 native flow, cancellations by shopper trigger `onAdditionalDetails()` event. You can make a `/payments/details` call to gain more insight into the transaction.
+  - If you already handle other 3DS2 errors by making a `/payments/details` call, then no changes are required and the specific handling for `Cancelled3DS2Exception` can be removed.
+  - If not yet implemented, you should update your systems to handle shopper cancellations using the new flow.
 - Dependency versions:

 ## Deprecated
+- `Cancelled3DS2Exception` is now deprecated. Shopper cancellation of the 3DS2 native flow triggers the `onAdditionalDetails()` event, enabling a `/payments/details` call for transaction insights.
