  • v0.5.1158 Streams now support BYOB readers and real `ByteLengthQueuingStrategy` accounting.
  • v0.5.1158 `Atomics.wait`, `notify`, and `waitAsync` now block and wake across agents using a shared `SharedArrayBuffer`.
  • v0.5.1158 `node:dns` and `node:dgram` perform real network I/O instead of stub behavior.
  • v0.5.1158 `AsyncLocalStorage` and `async_hooks` now propagate context across await, microtasks, timers, and `process.nextTick`.
