Release Notes

benoitc/gunicorn (gunicorn)

v25.1.0: Gunicorn 25.1.0

Compare Source

New Features

• Control Interface (gunicornc): Add interactive control interface for managing
  running Gunicorn instances, similar to birdc for BIRD routing daemon
  (PR #​3505)

  • Unix socket-based communication with JSON protocol
  • Interactive mode with readline support and command history
  • Commands: show all/workers/dirty/config/stats/listeners
  • Worker management: worker add/remove/kill, dirty add/remove
  • Server control: reload, reopen, shutdown
  • New settings: --control-socket, --control-socket-mode, --no-control-socket
  • New CLI tool: gunicornc for connecting to control socket
  • See Control Interface Guide for details

• Dirty Stash: Add global shared state between workers via dirty.stash
  (PR #​3503)

  • In-memory key-value store accessible by all workers
  • Supports get, set, delete, clear, keys, and has operations
  • Useful for sharing state like feature flags, rate limits, or cached data

• Dirty Binary Protocol: Implement efficient binary protocol for dirty arbiter IPC
  using TLV (Type-Length-Value) encoding
  (PR #​3500)

  • More efficient than JSON for binary data
  • Supports all Python types: str, bytes, int, float, bool, None, list, dict
  • Better performance for large payloads

• Dirty TTIN/TTOU Signals: Add dynamic worker scaling for dirty arbiters
  (PR #​3504)

  • Send SIGTTIN to increase dirty workers
  • Send SIGTTOU to decrease dirty workers
  • Respects minimum worker constraints from app configurations

Changes

• ASGI Worker: Promoted from beta to stable
• Dirty Arbiters: Now marked as beta feature

Documentation

• Fix Markdown formatting in /configure documentation

v25.0.3

Compare Source

What's Changed

Bug Fixes

• Fix RuntimeError when StopIteration raised in ASGI coroutine (#​3484)
• Fix passing maxsplit in re.split() as positional argument (deprecated in Python 3.13)

Documentation

• Updated sponsorship section and homepage

Full Changelog: benoitc/gunicorn@25.0.2...25.0.3

v25.0.2

Compare Source

What's Changed

Bug Fixes

• Fix ASGI concurrent request failures through nginx proxy
• Graceful disconnect handling for ASGI worker
• Lazy import dirty module for gevent compatibility

Other

• Increase CI timeout for signal tests on PyPy
• Remove trailing blank line in instrument/init.py

Full Changelog: benoitc/gunicorn@25.0.1...25.0.2

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

Compare Source

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
