 - `client.threads.stream()` now accepts `transport="sse"` (default) or

+### Fixed

+- Resource-scoped auth decorators now honor `actions=` and reject empty or
+  invalid action lists. Because unmatched custom-auth paths remain allowed,
+  deployments using action-scoped handlers should configure a global
+  default-deny handler; `langgraph-api` 0.10+ warns about uncovered paths at
+  startup. Resource-specific decorators retain matching `resources=` selectors
+  for backward compatibility; use `@auth.on(resources=...)` for other resources.
