[NewsBot]

Node.js v20.12.0 and v18.20.0 has been released.

Notable Changes

crypto: implement crypto.hash()

This patch introduces a helper crypto.hash() that computes
a digest from the input at one shot. This can be 1.2-2x faster
than the object-based createHash() for smaller inputs (<= 5MB)
that are readily available (not streamed) and incur less memory
overhead since no intermediate objects will be created.

const crypto = require('node:crypto');

// Hashing a string and return the result as a hex-encoded string.
const string = 'Node.js';
// 10b3493287f831e81a438811a1ffba01f8cec4b7
console.log(crypto.hash('sha1', string));

Notable Changes

Added support for import attributes

Support has been added for import attributes, to replace the old import
assertions syntax. This will aid migration by making the new syntax available
across all currently supported Node.js release lines.

This adds the with keyword which should be used in place of the previous
assert keyword, which will be removed in a future semver-major Node.js
release.

For example,

import "foo" assert { ... }

should be replaced with

import "foo" with { ... }
