Node.js 26.11.0 (Current)

Node.js 26.11.0 adds Buffer.stringLength(), http.isValidHeaderName() and isValidHeaderValue(), an HTTP/2 connectionWindowSize option, a --process-timeout flag, and histogram diff() and snapshot(). process.ref and unref graduate to stable, and Alpine Linux is promoted to tier 2.

Dependencies move to OpenSSL 3.5.9, npm 11.20.0 and undici 8.11.2. A same-day patch, 26.11.1, has no new features and only reverts three build and doc tooling commits.
