This release updates certifi-backed dependencies following the eMudhra CA compromise and fixes public-client OAuth authentication, empty visibility selections, generator transforms, and per-server timeouts for ordinary requests. FastMCP 4 uses system trust by default: follow the security notice to update operating-system, container, custom, and installer trust stores; upgrading FastMCP alone is insufficient. Thanks to our 11 contributors, including 6 first-time contributors.
