[dependabot]

Bumps gunicorn from 22.0.0 to 25.0.2.

Release notes

Sourced from gunicorn's releases.

Release 25.0.2

Bug Fixes

• Fix ASGI concurrent request failures through nginx proxy by normalizing sockaddr tuples to handle both 2-tuple (IPv4) and 4-tuple (IPv6) formats ([PR #3485](benoitc/gunicorn#3485))

• Fix graceful disconnect handling for ASGI worker to properly handle client disconnects without raising exceptions ([PR #3485](benoitc/gunicorn#3485))

• Fix lazy import of dirty module for gevent compatibility - prevents import errors when concurrent.futures is imported before gevent monkey-patching ([PR #3483](benoitc/gunicorn#3483))

Changes

• Refactor: Extract _normalize_sockaddr utility function for consistent socket address handling across workers

• Add license headers to all Python source files

• Update copyright year to 2026 in LICENSE and NOTICE files

25.0.1

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

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](benoitc/gunicorn#3460))
  • Inspired by Erlang's dirty schedulers
  • Asyncio-based with Unix socket IPC
