# Developer Release Notes

> Follow Interchange API, agent-tool, and platform contract changes.

Interchange publishes one release history for customer workflows and developer
contracts. Review it before adopting a newly documented field, tool, or
transition, and continue to treat the selected version's live schema as the
integration contract.
