Stream performance just got faster with ring buffer optimization in WHATWG tee operations, while DTLS and QUIC improvements shore up critical network paths.

Matteo Collina landed a major optimization that replaces array-backed queues with ring buffers in WHATWG stream operations [1], eliminating per-chunk `Array.prototype.shift` overhead on BYOB reads. This continues a performance series that systematically removes hot-path allocations from the streams stack. Meanwhile, James Snell shipped multiple DTLS improvements to the net module [2], strengthening Node's datagram transport layer as QUIC support matures. Tim Perry fixed a critical segfault in QUIC's fragmented client hello handling [3], addressing a crash path that could destabilize long-lived connections. On the testing side, Aviv Keller removed a flaky REPL test from the blocklist [4] after a V8 fix, and added `--test-coverage-include-all` support to the test runner [5] to improve coverage reporting on untested files. Over in doc-kit, the search navigation now keeps the URL hash synchronized with jumped-to anchors [6], fixing a UX gap where same-page hits left the address bar stale.
