v2.5

store_history_messages now defaults to False. Previously, agent run history messages were stored automatically. If your application relies on persisted message history for context, continuity, or audit purposes, you will need to explicitly enable this setting.

This change reduces default storage usage and improves performance for the majority of use cases where history persistence is not required.

Details

• Action required: If you rely on stored history, set store_history_messages=True on your agent configuration
• Default behavior now skips history storage, reducing write volume and storage cost
• No impact if you were already managing history explicitly

Who this is for: All teams upgrading to this version. Review your agent configurations to ensure history persistence is enabled where needed.
