 ### Bug fixes
 
 - `ServiceBusSessionReceiver.receiveMessages` and `ServiceBusSessionReceiver.subscribe` methods are updated to handle errors on the AMQP connection like a network disconnect in [#13956](https://github.com/Azure/azure-sdk-for-js/pull/13956). Previously, these methods only handled errors on the AMQP link or session.
+
   - This previously resulted in the promise returned by the `receiveMessages` method never getting fulfilled and the `subscribe` method not calling the user provided error handler.
   - The `receiveMessages` method will now throw `SessionLockLostError` when used in `peekLock` mode and return messages collected so far when used in `receiveAndDelete` mode to avoid data loss if errors on the AMQP connection are encountered.
   - When using the `subscribe`, the user provided `processError` callback will now be called with `SessionLockLostError` if errors on the AMQP connection are encountered.
