+## [3.0.0] - 2026-05-27
+### :magic_wand: Added
+* [SQLAlchemy ORM support](https://github.com/aws/aws-advanced-python-wrapper/blob/main/docs/using-the-python-wrapper/SQLAlchemySupport.md).
+
+### :bug: Fixed
+* New pooled connections created with stale credentials, and PostgreSQL error handler unable to correctly handle auth errors nested in connection errors ([PR #1231](https://github.com/aws/aws-advanced-python-wrapper/pull/1231)).
+* Read/Write Splitting plugins not subscribed to the execute pipeline, causing idle connections to not be correctly closed during failover ([PR #1117](https://github.com/aws/aws-advanced-python-wrapper/pull/1117)).
+
+### :crab: Breaking Changes
+> [!WARNING]
+> 3.0.0 changes the default `cluster_id` behavior. Applications connecting to **multiple database clusters** must now explicitly set a unique `cluster_id` for each cluster. See the [Cluster ID documentation](https://github.com/aws/aws-advanced-python-wrapper/blob/main/docs/using-the-python-wrapper/ClusterId.md) for details.
+>
+> #### Migration
+>
+> | Scenario | Action Required |
+> |---|---|
+> | Single database cluster | No changes required |
+> | Multiple database clusters | Review all connection strings and add a unique `cluster_id` parameter per cluster. See the [Cluster ID documentation](https://github.com/aws/aws-advanced-python-wrapper/blob/main/docs/using-the-python-wrapper/ClusterId.md) for configuration guidance. |

 ## [2.1.0] - 2026-02-11
