## [2.0.0] - 2026-01-14
### :crab: Breaking Changes
> [!WARNING]
> - 2.0 removes support for Python 3.8 and 3.9.

### :magic_wand: Added
* Python 3.12 and 3.13 support ([PR #1052](https://github.com/aws/aws-advanced-python-wrapper/pull/1052)).
* [Simple Read/Write Splitting Plugin](https://github.com/aws/aws-advanced-python-wrapper/blob/main/docs/using-the-python-driver/using-plugins/UsingTheSimpleReadWriteSplittingPlugin.md) (`srw`). This plugin adds functionality to switch between endpoints via calls to the Connection#setReadOnly method. It does not rely on cluster topology. It relies purely on the provided endpoints and their DNS resolution ([PR #1048](https://github.com/aws/aws-advanced-python-wrapper/pull/1048)).
* Wrapper resource cleanup method `aws_advanced_python_wrapper.release_resources()`. This method should be called at program exit to properly clean up background threads and resources ([PR #1066](https://github.com/aws/aws-advanced-python-wrapper/pull/1066)).

### :bug: Fixed
* Sliding expiration cache bug which causes delay upon exit ([PR #1043](https://github.com/aws/aws-advanced-python-wrapper/pull/1043)).
* Unnecessary boto3 call to verify region in IAM plugin which causes performance issues ([PR #1042](https://github.com/aws/aws-advanced-python-wrapper/pull/1042)).
* MySQL connections hanging during garbage collection ([PR #1063](https://github.com/aws/aws-advanced-python-wrapper/pull/1063)).
* Incorrect MySQL host alias query ([PR #1051](https://github.com/aws/aws-advanced-python-wrapper/pull/1051)).
* `ImportError` when MySQL Connector/Python C Extension isn't available ([PR #1038](https://github.com/aws/aws-advanced-python-wrapper/pull/1038)).
* Background threads being created at import time ([PR #1066](https://github.com/aws/aws-advanced-python-wrapper/pull/1066)).

### :crab: Changed
* Refactor host list provider ([PR #1065](https://github.com/aws/aws-advanced-python-wrapper/pull/1065)).
* Performance optimizations ([PR #1072](https://github.com/aws/aws-advanced-python-wrapper/pull/1072)).
* Update documentation with required db user permissions for Multi-AZ DB Cluster and Blue/Green support ([PR #1061](https://github.com/aws/aws-advanced-python-wrapper/pull/1061)).

## [1.4.0] - 2025-10-17
### :magic_wand: Added
* [EFM v2](https://github.com/aws/aws-advanced-python-wrapper/blob/main/docs/using-the-python-driver/using-plugins/UsingTheHostMonitoringPlugin.md#host-monitoring-plugin-v2), an improved alternate version of the `efm` plugin which addresses issues such as garbage collection and monitoring stability, is now live!
