Prerelease: no

Release notes:

1.0.1 - 2026-04-09

> [!IMPORTANT] > Security hardening for `FileCheckpointStorage`: Checkpoint deserialization now flows through a restricted unpickler by default, which only permits a built-in set of safe Python types and all agent_framework framework types. If your application stores custom types in checkpoints, pass their "module:qualname" identifiers via the new allowed_checkpoint_types constructor parameter — otherwise loads will raise WorkflowCheckpointException. See Security Considerations for details and the opt-in format.
