Changelog

Sourced from uvicorn[standard]'s changelog.

0.50.1 (July 6, 2026)

Fixed

• Split comma-separated Sec-WebSocket-Protocol values in the websockets-sansio implementation (#3019)

0.50.0 (July 4, 2026)

If you use WebSockets, note that --ws auto now picks the websockets-sansio implementation. You shouldn't need it, but you can pin --ws websockets to get the deprecated legacy one back.

Changed

• Exit with the dedicated code 3 on any startup failure: app loading, socket bind and lifespan startup errors previously exited with a mix of 0, 1 and 3 (#3001)
• Stop the multiprocess supervisor when a worker exits with code 3 instead of restarting it forever (#3001)
• Default --ws auto to websockets-sansio when websockets is installed (#2985)
• Skip the eager app import in the parent process with --reload or --workers, fixing a memory regression introduced in 0.47.0 (#3012)
• Build a fresh asgi scope dict per request (#2977)
• Cache the asgi scope sub-dict per connection (#2976)
• Avoid copying single-frame WebSocket payloads in websockets-sansio (#2983)
• Memoize trusted host checks in ProxyHeadersMiddleware (#2970)
• Replace click.style with an internal ANSI style helper (#2981)

Deprecated

• Deprecate the legacy websockets implementation; use websockets-sansio or wsproto instead (#2985)

0.49.0 (June 3, 2026)

Changed

• Bump httptools minimum version to 0.8.0 (#2962)
• Consume duplicate forwarding headers in ProxyHeadersMiddleware (reverses the 0.48.0 behavior of ignoring them) (#2971)

0.48.0 (May 24, 2026)

Changed

• Default ssl_ciphers to None and use OpenSSL defaults (#2940)

Fixed

• Ignore duplicate forwarding headers in ProxyHeadersMiddleware (#2944)

0.47.0 (May 14, 2026)

Added

• Add ssl_context_factory for custom SSLContext configuration (#2920)

Changed
