A network inspector bug that mangled absolute URLs in HTTP requests is now fixed, while llhttp gets a maintenance bump and Undici optimizes its HTTP/2 client with authority caching.

The inspector was doubling up on URLs when clients passed absolute paths instead of relative ones [1], creating malformed request logs like `http://hosthttp://host/path` — a trap for anyone debugging network traffic in production. The fix handles absolute URLs directly while preserving backward compatibility for relative paths [3]. Separately, llhttp shipped a patch update to 9.4.1 [2], landing upstream in Node with the usual automated dependency sync. Over in Undici, two separate performance wins landed back-to-back: HTTP/2 authority values are now cached to avoid redundant string construction [4], and duplicate request stream setup logic collapsed into a single path [5]. The Node-API CTS gained test coverage for SharedArrayBuffer [6], bridging a gap between the test suite and the compatibility standard. Nothing here demands an emergency patch, but the inspector fix closes a real debugging footgun.
