ESM require() now throws a dedicated race-condition error (
adeb14a)
Node adds ERR_REQUIRE_ESM_RACE_CONDITION to distinguish a module that is being require()d before async loading has finished. The loader now throws this specific error in the race path, which should make the failure mode clearer and easier to diagnose.
Blob constructor now follows sequence conversion more closely (
df5a925)
The Blob constructor was reworked to use WebIDL sequence conversion instead of manually rejecting non-iterables and stringifying parts. This should bring argument handling closer to the spec, especially around coercion order and mixed part types.
test_runner events gain a stable testId (
31b9e60)
Test events now include a testId, and the API docs plus fixture coverage were updated accordingly. This gives consumers a more reliable way to correlate test lifecycle events across streams and tooling.
ReadableStream-from-iterable is simplified (1266013)
readableStreamFromIterable() was refactored to use direct async iteration and to validate iterator methods explicitly. The change also tightens error handling around iterator results and cancellation while removing older helper machinery.
isDataView() switches to a JS-only implementation (
1bc6394)
Node moved isDataView() off the native implementation and onto the JS path. That reduces native surface area and keeps the type check logic in one place.
Inspector and error source locations use context-free V8 columns (ad44dc4)
Source-location plumbing was updated to read column information without a context argument in the inspector and error formatting paths. This is a small runtime compatibility cleanup for newer V8 APIs.
Other misc changes
- Re-enabled undici WPTs in the daily wpt.fyi job.
- Broadened stale bot automation and related contributor docs.
- Minor lint, docs, and tooling cleanup, including OpenSSL test-shared nix config and a strict-mode contextify test.
