Hello and welcome to your Node.js weekly recap for October 26th through November 2nd.
30 pull request activity items, 30 additional commits this week.
The lead pattern is stabilization for the next major while fixing subtle correctness bugs in current primitives. The version 27 alpha is cut, and much of the week tightens async context handling, memory accounting, and native safety.
First, version 27 takes shape. PR 67062 published version 27 alpha, dated October 28th, moving the V8 engine to 15 point 6, up from 14 point 6 in Node 26. The notes highlight new JavaScript features enabled by default, including precise summation for math, locale variants, and new iterator helpers for joining,…
Second, web streams get more predictable. Three changes from Matteo Collina address async context and closing. PR 67052 keeps the async context of pipe to watchers, so source close and error steps no longer inherit the context of whoever closed the stream. PR 67055 applies the same principle to writes bridged from…
Third, native boundaries are hardened. On transport security, PR 66949 replaces test hooks with a permanent fixture certificate authority on the compiled block list, exercising the real…
