🦀 Breaking Changes

Warning

• 2.0 removes support for Python 3.8 and 3.9.

🪄 Added

• Python 3.12 and 3.13 support (PR #1052).
• Simple Read/Write Splitting Plugin (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).
• 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).

🐛 Fixed

• Sliding expiration cache bug which causes delay upon exit (PR #1043).
• Unnecessary boto3 call to verify region in IAM plugin which causes performance issues (PR #1042).
• MySQL connections hanging during garbage collection (PR #1063).
• Incorrect MySQL host alias query (PR #1051).
• ImportError when MySQL Connector/Python C Extension isn't available (PR #1038).
• Background threads being created at import time (PR #1066).

🦀 Changed

• Refactor host list provider (PR #1065).
• Performance optimizations (PR #1072).
• Update documentation with required db user permissions for Multi-AZ DB Cluster and Blue/Green support (PR #1061).
