 ### Added
 
+- Per-provider `cache_duration` option (seconds) forwarded to the
+  underlying library; lets consumers tighten or extend the 24h default
+  TTL for the cached OIDC discovery document and JWKS
 - Per-provider `http_client_options` block (`timeout`, `proxy`, `verify`)
   forwarded to the underlying Guzzle HTTP client used by league/oauth2-client.
   Closes the long-standing inability to bound HTTP requests to the IdP.
