`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

- 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)

`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

`v24.1.1`

Compare Source

Bug Fixes

Fix forwarded_allow_ips and proxy_allow_ips to remain as strings for backward
compatibility with external tools like uvicorn. Network validation now uses strict
mode to detect invalid CIDR notation (e.g., 192.168.1.1/24 where host bits are set)
(#3458,
PR #3459)

Full Changelog: https://github.com/benoitc/gunicorn/compare/24.1.0...24.1.1

`v24.1.0`: Gunicorn 24.1.0

Compare Source

New Features

Official Docker Image: Gunicorn now publishes official Docker images to GitHub Container Registry (PR #3454)
- Available at ghcr.io/benoitc/gunicorn
- Based on Python 3.12 slim image
- Uses recommended worker formula (2 × CPU + 1)
- Configurable via environment variables
PROXY Protocol v2 Support: Extended PROXY protocol implementation to support the binary v2 format in addition to the existing text-based v1 format (PR #3451)
- New --proxy-protocol modes: off, v1, v2, auto
- auto mode (default when enabled) detects v1 or v2 automatically
- v2 binary format is more efficient and supports additional metadata
- Works with HAProxy, AWS NLB/ALB, and other PROXY protocol v2 sources
CIDR Network Support: --forwarded-allow-ips and --proxy-allow-from now accept CIDR notation (e.g., 192.168.0.0/16) for specifying trusted networks (PR #3449)
Socket Backlog Metric: New gunicorn.socket.backlog gauge metric reports the current socket backlog size on Linux systems (PR #3450)
InotifyReloader Enhancement: The inotify-based reloader now watches newly imported modules, not just those loaded at startup (PR #3447)

Bug Fixes

Fix signal handling regression where SIGCLD alias caused "Unhandled signal: cld" errors on Linux when workers fail during boot (#3453)
Fix socket blocking mode on keepalive connections preventing SSL handshake failures with async workers (PR #3452)
Use smaller buffer size in finish_body() for faster timeout detection on slow or abandoned connections (PR #3453)
Handle SSLWantReadError in finish_body() to prevent worker hangs during SSL renegotiation (PR #3448)
Log SIGTERM as info level instead of warning to reduce noise in orchestrated environments (PR #3446)
Print exception details to stderr when worker fails to boot (PR #3443)
Fix unreader.unread() to prepend data to buffer instead of appending (PR #3442)
Prevent RecursionError when pickling Config objects (PR #3441)
Use proper exception chaining with raise from in glogging.py (PR #3440)
