+## 1.5.3
+  - Fix: With `config_mode => 'advanced'`, event hub-specific settings (`initial_position`, `max_batch_size`, `prefetch_count`, `receive_timeout`, `initial_position_look_back`) were being ignored and replaced with global defaults. These settings are now correctly applied per event hub [#104](https://github.com/logstash-plugins/logstash-input-azure_event_hubs/pull/104)
+
 ## 1.5.2
   - Updated JWT dependency [#101](https://github.com/logstash-plugins/logstash-input-azure_event_hubs/pull/101)
