chore(deps): bump the python-production group with 2 updates

[dependabot]

Updates the requirements on uvicorn and httpx2 to permit the latest version.
Updates uvicorn to 0.54.0

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.

HTTP/2 support remains experimental. Install zttp>=0.0.34 and enable it with --http zttp --http2.

Added

• Add HTTP/2 response trailers through the ASGI http.response.trailers extension. Clients must send TE: trailers to receive them (#3146)
• Add HTTP/2 103 Early Hints through the ASGI http.response.early_hint extension (#3137)

0.53.0 (September 14, 2026)

This release adds experimental HTTP/2 support through zttp. Enable it with --http zttp --http2. Upgrade-based h2c and WebSockets over HTTP/2 are not supported.

Added

• Add experimental HTTP/2 support through zttp (#2982, #3101)
• Add support for zuvloop (#3104)

Fixed

• Handle comma-separated, case-insensitive Connection: close tokens across HTTP implementations (#3103)
• Trust IPv6 loopback in the default FORWARDED_ALLOW_IPS value (#3119)
• Cancel the HTTP keep-alive timer when upgrading to WebSocket (#3107)

0.52.4 (August 18, 2026)

Fixed

• Remove duplicate Date headers from accepted WebSocket handshakes with websockets-sansio (#3078)

0.52.3 (August 13, 2026)

Updates httpx2 to 2.13.1

Release notes

Sourced from httpx2's releases.

v2.13.1

Highlights

📤 Accurate file upload lengths

Passing a file as content= now calculates Content-Length from its remaining bytes, respecting the current file position (#1214).

🔐 Reliable proxy TLS and HTTP/2 negotiation

TLS hostname overrides now apply inside HTTP proxy tunnels without affecting the proxy's own TLS connection (#1223). HTTP/2 is advertised first when enabled, and HTTP/1.1 is omitted when disabled (#1155).

🧹 Clean WebSocket shutdown

The sync WebSocket keepalive thread now exits cleanly when a ping races with connection shutdown (#1228).

httpx2

Fixed

• Calculate Content-Length from the remaining bytes when a file is passed as content=, respecting its current position (#1214).
• Stop the sync WebSocket keepalive thread cleanly when a ping races with connection shutdown (#1228).

httpcore2

Fixed

• Honor the sni_hostname extension for TLS inside HTTP proxy tunnels without applying it to the proxy's TLS connection (#1223).
• Prefer HTTP/2 during TLS protocol negotiation when enabled, and stop advertising HTTP/1.1 when it is disabled (#1155).
