3.21.2 (2026-09-23)

Changed

• Minor performance improvement in CaseInsensitiveDict, with an expected gain of up to 1%.
• Reduced overhead in response attribute access and request preparation.
• python -m niquests.help now reports the WebSocket backend and version through websocket.backend
  and websocket.version, replacing websocket.wsproto.

Fixed

• Fixed a quadratic performance issue in iter_lines() when processing long lines.
• Corrected the generic key type in CaseInsensitiveDict to require str or bytes.
• Fixed an intermittent WASI HTTP 0.2 upload failure when the host closes the output stream after the request body is written.

Misc

• Officially recognized websockets as a supported WebSocket backend alongside wsproto.
  Requires Python 3.9 or newer and urllib3-future 2.25.900 or newer.
  Install it with pip install "niquests[ws-fast]". When both backends are installed, use
  wss+fast://example.org/ to explicitly select websockets. Run python -m niquests.help
  to check which backend is selected by default.
• Documented full-duplex WebSocket communication over HTTP/1.1 with urllib3-future 2.25.900 or newer.
• Documented installation via a prebuilt alternative wheel that isolates urllib3-future, with no local build required.
