+A maintenance release for the 3.x line. A single unrecognized JWKS key — Ed25519, which Rauthy and Ory Hydra publish by default — no longer poisons the entire key cache, alongside fixes for Azure scope fallback, OpenAPI `deepObject` query serialization, schema compression, and transformed tool `required` ordering.
