Good morning, it's July 25th, 2026, and this is your Node.js briefing.
The headline today is networking across worker threads. Guy Bedford's PR 64725 lets a `net.BoundSocket` be transferred between threads via `postMessage`, so one thread can reserve a port and hand it off to another without racing on the bind. That builds directly on recent groundwork: Matteo Collina's commit added…
The second theme is test reliability. A cluster of PRs from Trivikram, Joyee Cheung, and Matteo Collina all target flaky CI: fixing a timer race in the event loop delay test, extending timeouts for slow debugger probe tests, unflaking debugger and REPL tests on macOS, and separating stream-close from write-callback…
A smaller but notable thread: URL Pattern correctness. Two PRs from Archkon, 64733 and 64735, fix property ordering in URL Pattern results to match the WebIDL spec, paired with a CODEOWNERS update adding the URL team to that file.
Worth flagging individually: PR 64720 fixes a segfault in QUIC when a client hello arrives fragmented across packets, by deferring session setup until ALPN actually resolves — a real crash fix, not just cleanup. And PR 64721 wires perfetto tracing into CI,…
