httpx2 2.13.1

v2.13.1

on Python PyPI

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).
