0.1.4

django-stateless-mcp 0.1.4

Added

• Subscription streams (SEP-2575). subscriptions/listen — the
  2026-07-28 replacement for the standing GET stream, whose POST response is
  itself the stream — is now served: under ASGI the response streams live SSE
  frames (ack, then filtered, subscription-id-tagged events) until the client
  disconnects; under WSGI, where a live stream would pin a worker, the view
  answers an explicit 501 unsupported_deployment instead of hanging. Routed
  by the spec's required mcp-method header; every other request is
  byte-identical to before. Wire an external SubscriptionBus
  (MCPServer(subscriptions=…)) for multi-replica event fan-out. The
  conformance suite's server-stateless scenario now passes 30/30 and has
  left the expected-failures baseline. (ADR-0020)

Fixed

• Worker-thread database connections are now recycled. Sync tools run
  in the SDK's thread pool, which Django's request_finished cleanup never
  reaches — connections opened there were never aged out or health-checked,
  a slow stale-connection leak under sustained load. The view now runs
  Django's own close_old_connections inside that pool after each request,
  honouring CONN_MAX_AGE exactly as request threads do. (ADR-0021)

Changed

• mcp_view's published return annotation widens to HttpResponseBase
  (streaming responses are not HttpResponse subclasses).
• The example project registers test_trigger_tool_change /
  test_trigger_prompt_change tools and an in-memory subscription bus.
