v3.4.5: Key Change

on GitHub

FastMCP 3.4.5 collects five fixes for the 3.x line. The one that prompted it: a single Ed25519 key in a JWKS — which Rauthy, Ory Hydra, and some Keycloak configurations publish by default — made JWTVerifier reject every token, including ones correctly signed by supported keys in the same set.
