## [3.0.0] - 2026-06-02

### :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. |

### :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)).

## [2.1.0] - 2026-02-11
### :magic_wand: Added
* [Failover v2 Plugin](https://github.com/aws/aws-advanced-python-wrapper/blob/main/docs/using-the-python-wrapper/using-plugins/UsingTheFailoverPlugin.md), an improved version of the failover plugin with enhanced reliability ([PR #1079](https://github.com/aws/aws-advanced-python-wrapper/pull/1079)).
