Release Notes

v26.0.0

Compare Source

Breaking Changes

  • Eventlet worker removed: The eventlet worker class has been dropped. Migrate to gevent, gthread, or tornado.

New Features

  • ASGI Framework Compatibility Suite: New end-to-end compatibility test harness covering Starlette, FastAPI, Litestar, Quart, Sanic, and BlackSheep. Current grid passes 438/444 tests (98%).
  • ASGI Test Suite Expansion: 134 additional ASGI unit tests covering protocol semantics, lifespan, websockets, and chunked framing.

Security

  • HTTP/1.1 Request-Target Validation (RFC 9112 sections 3.2.3, 3.2.4):
    • Reject authority-form request-target outside CONNECT
    • Reject asterisk-form request-target outside OPTIONS
    • Reject relative-reference request-targets
  • Header Field Hardening (RFC 9110):
    • Reject control characters in header field-value (section 5.5)
    • Reject forbidden trailer field-names (section 6.5.1)
    • Reject Content-Length list form (RFC 9112 section 6.3)
  • Request Smuggling Hardening:
    • Tighten keepalive gate and scope finish_body byte cap
    • Keep _body_receiver alive across the keepalive smuggling gate so pipelined requests cannot re-enter a closed body
    • Address parser/protocol findings from a six-point WSGI/ASGI audit
  • PROXY Protocol (ASGI): Enforce proxy_allow_ips and tighten v1/v2 parsing in the ASGI callback parser.
  • Connection Draining: Drain the connection on close per RFC 9112 section 9.6 to prevent reset-on-close truncation.

Bug Fixes

  • Body Framing on HEAD/204/304:
    • Keep Content-Length on HEAD and 304 responses (#​3621)
    • Drop body framing on HEAD/204/304 even when the framework set it
    • Warn once when an ASGI app emits a body for a no-body response
  • HTTP/2 ASGI:
    • Fix _handle_stream_ended to set _body_complete in the async HTTP/2 handler so request bodies finalize correctly on stream end
    • Add InvalidChunkExtension mapping and fast-parser support in ASGI tests (#​3565)
  • HTTP/1.1 100-Continue: Stop adding Transfer-Encoding: chunked to 100-Continue interim responses.
  • WebSocket Close Handshake (RFC 6455):
    • Comply with the close handshake state machine
    • Close the transport after the close handshake completes
    • Fix binary send when the text key is None
  • Early Hints: Validate headers in the early_hints callback to match process_headers; pass only the header name to InvalidHeader (#​3588).
  • ASGI Framework Fixes:
    • Fix ASGI disconnect handling for Django-style apps
    • Fix Litestar request handling (use raw ASGI receive for body/headers)
    • Fix Litestar HTTP endpoints for compatibility tests
    • Fix Quart headers endpoint to normalize keys to lowercase
    • Fix Quart WebSocket close test app (missing accept())
    • Fix duplicate Transfer-Encoding header for BlackSheep streaming

Refactoring

  • Split BodyReceiver._closed into separate transport and body-wait flags for clearer keepalive/EOF semantics.

Changes

  • Fast HTTP Parser: Require gunicorn_h1c >= 0.6.5. Drop the last python_only test markers; the C extension is now used wherever available (CPython only; PyPy continues to use the Python parser).
  • Test Dependencies: Add h2 and uvloop to the testing extra; remove eventlet.
  • Docker Build: Bump GitHub Actions docker/setup-qemu-action, docker/setup-buildx-action, docker/login-action, docker/build-push-action, and docker/metadata-action to current major versions.
