BlockList gets a comprehensive performance overhaul, Windows file handles gain native support, and stream abort logic finally passes spec.

James Snell shipped a sweeping optimization to net.BlockList [1] that eliminates shared pointers, adds read/write locking, introduces bulk address operations, and includes a new clear method, addressing both correctness and speed across the entire API. Windows developers now have a path forward: a new windowsHandle option on fs.createReadStream() and fs.createWriteStream() [2] wraps raw Win32 HANDLEs through CRT file descriptors, fixing the EBADF failures that plagued inherited pipe handles from other processes. The streams implementation fixed a critical recursive abort bug [3] by rechecking stream state after signaling abort, as the spec requires, finally passing WPT and removing its expected-failure entry. Separately, zlib tightened ZIP parsing by rejecting ambiguous EOCD records [4], scanning candidates in a consistent tail window to prevent trailing padding from changing which central directory gets used. Buffer allocation gains optional alignment support [5], letting you allocate 4096-byte aligned buffers for direct file I/O without wrapper overhead. On the infrastructure side, docker-node switched to consuming dist/index.json for version resolution [6], simplifying the release pipeline and removing HTML parsing fragility [7].

Action items

→ Review net.BlockList usage in production for lock contention opportunities from the new read/write locking nodejs/node [plan]
→ Test fs.createReadStream with windowsHandle option if you inherit pipes from other processes on Windows nodejs/node [plan]
→ Verify ZIP file handling in your zlib code paths with padded archives nodejs/node [monitor]
