- Added several Node extension features: SyncWriteStream, llhttp‑based HTTPParser, native TLSWrap, and a native uv pipe implementation with NativePipe and FdTable.
- Fixed core and runtime stability issues including UV pipe handle lifecycle, UV loop memory leak, non‑blocking stdio handling, and canonical watch path caching.
- Improved security and permission handling by normalizing IPv4‑mapped IPv6 addresses, denying numeric hostname bypasses, and adding OTEL exporter timeout.
