- Deprecate instantiating node:http classes without new, passing an empty string to options.shell, and HTTP/2 priority signaling; future versions may error or remove them.
- Stabilize assert.partialDeepStrictEqual() and add numerous new web‑stream utilities (e.g., readableWebStream, Dir resource management, duplex/web conversions) plus http2 diagnostics channels and implicit read permission for entrypoints.
- Introduce minor ergonomics such as autoClose option for FileHandle readableWebStream, Dir explicit close handling, util.styleText('none'), and URL.createObjectURL()/revokeObjectURL() APIs.
