Stream iter semantics tightened across writers and pipelines (
7aba44d, 6e1789a, 1ed73da, 5ada066, 33f85fe, 60b8f28, 7fafadf, 7089049, e6332d6, 57e0f33, 3c8f77f, 7b61c62)
The experimental stream/iter API picked up a substantial round of behavior fixes. Writer arguments now follow Web IDL conversion rules, pull()/pipeTo() normalize sources at call time, transforms preserve their receiver, and push/broadcast writers were adjusted so capacity, draining, end-of-stream, and async disposal behave more predictably.
fs.mkdtemp() now returns Buffer when given a Buffer prefix (
1f53d7e)
mkdtemp() and its promise variant now preserve Buffer input by returning a Buffer output instead of always coercing to string. That fixes a long-standing type inconsistency in the fs API and aligns the result with the caller’s prefix type.
ffi helpers now throw when required args are omitted (
7147a3e)
The memory helper methods in the ffi addon no longer quietly return undefined when a required argument is missing. That makes omitted-argument bugs observable instead of being mistaken for a legitimate zero-value read or write.
Undici updated to 8.10.2 (
8af7545)
Node bundled a newer Undici release, bringing along a broad set of internal HTTP client and proxy changes. This can affect fetch and related network behavior even though the update is dependency-driven.
QUIC stop-sending callback guard removed (
695f01f)
Node simplified its ngtcp2 stop-sending callback handling in QUIC code. This is a targeted internal fix for the QUIC session path and likely reduces wrapper complexity around the callback field.
Other misc changes
- Typings updates for internal bindings (
fs_event_wrap,stream_pipe,profiler) - Docs-only updates, including
node:modulesheader wording andstream_iterAPI text - Test stability fixes for benchmark timing, DNS timeout comparisons, WASI threads, watch restarts, proxy resets, EPIPE handling, and core-dump behavior
