Windows build now supports PGO and Thin LTO (
262dee5)
Node’s Windows build/configuration was extended to support profile-guided optimization and Thin LTO flows, including new CLI/config flags and corresponding MSVC link/compiler settings. This is a significant build-system change that can affect release performance and how binaries are produced on Windows.
MockTimers now matches the public Timeout disposal API (
a5b3d76)
Fake timer handles exposed by the test runner now implement Timeout.close() and Timeout[Symbol.dispose]() just like real timers. That keeps disposal-based patterns from throwing when tests use MockTimers, and the new coverage locks in the behavior.
HTTP proxy NO_PROXY matching is fixed for leading-dot domains (
d44a71a)
The proxy matcher no longer treats .example.com as matching partial names like notexample.com or badexample.com; it now requires an exact suffix boundary or the exact host. This closes a correctness bug in proxy bypass behavior that could send traffic through the wrong path.
Crypto key generation is hardened against inherited properties (
800f582)
generateKeyPair* now checks key type names as own properties instead of walking the prototype chain, preventing inherited values like toString or constructor from being accepted as supported algorithms. That’s a small but important hardening fix for public crypto input validation.
WebCrypto crypto util lookup is hardened against prototype pollution (
1f6f3ac)
The internal kKeyOps lookup was tightened with a null-prototype object, reducing the risk of prototype-chain interference in crypto utility dispatch. The accompanying test coverage confirms the lookup stays safe.
Debugger probe tests now normalize a known inspector crash (
3dc06ae)
The probe harness now treats a trailing inspector segfault as completion for a pre-existing teardown issue, so CI doesn’t fail on machines where the debuggee exits too quickly. This is a pragmatic test-only workaround, not a product fix, but it stabilizes the suite until the upstream bug is resolved.
Test runner rerun edge case around ambiguous children is fixed (
633b963)
Suite reruns no longer double-start direct children, which could re-run synthetic descendants with already-incremented disambiguators and produce spurious failures. The regression coverage adds an ambiguous shared-helper scenario and updates expected rerun state to match.
Other misc changes
- Streams WPT fixtures updated to a newer upstream snapshot and related metadata.
- Argon2 docs corrected to show inclusive parameter bounds.
- Test coverage added for MockTimers disposal methods, debugger probe normalization, crypto keygen validation, and rerun bookkeeping.
