Node compatibility jumps across core networking and addons
This week focused heavily on closing the biggest Node parity gaps. TLS/server auth behavior was tightened, node:http and node:http2 picked up multiple correctness fixes, node:net gained resetAndDestroy() plus more option support, and worker_threads semantics were aligned more closely with Node. Native addons also got a safer N-API story, including deferred finalizers, napi_async_init/destroy, and a rollback of real V8 handle scopes after crashes in existing addons.
Performance wins in hot runtime paths
Several changes were aimed squarely at throughput and tail latency: the event-loop polling path was reworked to avoid scanning every live handle, HTTP parsing and stream writes were trimmed, and worker/MessagePort messaging was sped up with raw post-message ops and synchronous drain loops. These should show up most in chatty networking and IPC-heavy workloads.
Filesystem, process, and platform behavior moved closer to Node
A broad set of smaller-but-important compatibility fixes landed in fs, child_process, process, and path handling. Highlights include fs.stat/lstat throwIfNoEntry support, fs.watch path normalization, Windows named-pipe reconnect fixes, spawnSync stdio inheritance support, process.env and debugPort edge-case alignment, and pathToFileURL() improvements for Windows and special characters.
Web/crypto/runtime semantics were tightened
structuredClone() now correctly rejects non-serializable platform objects like Request, Response, Headers, and streams. TLS crypto handling also got stricter validation and better body draining, RSA OAEP parameters are now normalized and validated, and macOS permission checks now compare filesystem-equivalent paths to avoid false mismatches.
