Release Notes

benoitc/gunicorn (gunicorn)

v25.0.1

Compare Source

Bug Fixes

• Fix ASGI streaming responses (SSE) hanging: add chunked transfer encoding for
  HTTP/1.1 responses without Content-Length header. Without chunked encoding,
  clients wait for connection close to determine end-of-response.

Changes

• Update celery_alternative example to use FastAPI with native ASGI worker and
  uvloop for async task execution

Testing

• Add ASGI compliance test suite with Docker-based integration tests covering HTTP,
  WebSocket, streaming, lifespan, framework integration (Starlette, FastAPI),
  HTTP/2, and concurrency scenarios

v25.0.0: Gunicorn 25.0.0

New Features

• Dirty Arbiters: Separate process pool for executing long-running, blocking
  operations (AI model loading, heavy computation) without blocking HTTP workers
  (PR #​3460)

  • Inspired by Erlang's dirty schedulers
  • Asyncio-based with Unix socket IPC
  • Stateful workers that persist loaded resources
  • New settings: --dirty-app, --dirty-workers, --dirty-timeout,
    --dirty-threads, --dirty-graceful-timeout
  • Lifecycle hooks: on_dirty_starting, dirty_post_fork,
    dirty_worker_init, dirty_worker_exit

• Per-App Worker Allocation for Dirty Arbiters: Control how many dirty workers
  load each app for memory optimization with heavy models
  (PR #​3473)

  • Set workers class attribute on DirtyApp (e.g., workers = 2)
  • Or use config format module:class:N (e.g., myapp:HeavyModel:2)
  • Requests automatically routed to workers with the target app
  • New exception DirtyNoWorkersAvailableError for graceful error handling
  • Example: 8 workers × 10GB model = 80GB → with workers=2: 20GB (75% savings)

• HTTP/2 Support (Beta): Native HTTP/2 (RFC 7540) support for improved performance
  with modern clients (PR #​3468)

  • Multiplexed streams over a single connection
  • Header compression (HPACK)
  • Flow control and stream prioritization
  • Works with gthread, gevent, and ASGI workers
  • New settings: --http-protocols, --http2-max-concurrent-streams,
    --http2-initial-window-size, --http2-max-frame-size, --http2-max-header-list-size
  • Requires SSL/TLS and h2 library: pip install gunicorn[http2]
  • New example: examples/http2_gevent/ with Docker and tests

• HTTP 103 Early Hints: Support for RFC 8297 Early Hints to enable browsers to
  preload resources before the final response
  (PR #​3468)

  • WSGI: environ['wsgi.early_hints'](headers) callback
  • ASGI: http.response.informational message type
  • Works with both HTTP/1.1 and HTTP/2

• uWSGI Protocol for ASGI Worker: The ASGI worker now supports receiving requests
  via the uWSGI binary protocol from nginx
  (PR #​3467)

Bug Fixes

• Fix HTTP/2 ALPN negotiation for gevent and eventlet workers when
  do_handshake_on_connect is False (the default). The TLS handshake is now
  explicitly performed before checking selected_alpn_protocol().

• Fix setproctitle initialization with systemd socket activation
  (#​3465)

• Fix Expect: 100-continue handling: ignore the header for HTTP/1.0 requests
  since 100-continue is only valid for HTTP/1.1+
  (PR #​3463)

• Fix missing _expected_100_continue attribute in UWSGIRequest

• Disable setproctitle on macOS to prevent segfaults during process title updates

• Publish full exception traceback when the application fails to load
  (#​3462)

• Fix ASGI: quick shutdown on SIGINT/SIGQUIT, graceful on SIGTERM

Deprecations

• Eventlet Worker: The eventlet worker is deprecated and will be removed in
  Gunicorn 26.0. Eventlet itself is no longer actively maintained.
  Please migrate to gevent, gthread, or another supported worker type.

Changes

• Remove obsolete Makefile targets
  (PR #​3471)
• Replace RST with markdown documentation format
