Release notes

Sourced from uvicorn's releases.

Version 0.54.0

📨 Send metadata after the response body

uvicorn 0.54.0 adds response trailers and 103 Early Hints to its experimental HTTP/2 implementation through zttp.

uv add uvicorn==0.54.0 "zttp>=0.0.34"

• Send HTTP/2 response trailers (#3146). The ASGI http.response.trailers extension lets applications send metadata, such as checksums, after the response body. Clients must send TE: trailers to receive them. Multiple trailer messages are combined before completing the response.
• HTTP/2 remains experimental and opt-in. Enable it with --http zttp --http2. Upgrade-based h2c and WebSockets over HTTP/2 remain unsupported.

💡 Hint at resources before the final response

• Send 103 Early Hints over HTTP/2 (#3137). Applications can use the ASGI http.response.early_hint extension to send resource hints before the final response. Each supplied link becomes a separate Link header.
