v8.0.0

Compare Source

Node.js builtin modules prefixed with node: are now in a separate group by default (regex: ^node:), above the packages group. (Node.js builtins without node: are still sorted together with npm packages like before.)

Before:

import fs from "fs";
import _ from "lodash-es";
import { rmSync } from "node:fs";

After:

import { rmSync } from "node:fs";

import fs from "fs";
import _ from "lodash-es";

This is only a breaking change if you use the node: prefix in imports, and only in the form of that you need to autofix your files.
