OpenSSL 3.0

Node.js now includes OpenSSL 3.0, specifically quictls/openssl which provides QUIC support. With OpenSSL 3.0 FIPS support is again available using the new FIPS module. For details about how to build Node.js with FIPS support please see

While OpenSSL 3.0 APIs should be mostly compatible with those provided by OpenSSL 1.1.1, we do anticipate some ecosystem impact due to tightened restrictions on the allowed algorithms and key sizes.

If you hit an ERR_OSSL_EVP_UNSUPPORTED error in your application with Node.js 17, it’s likely that your application or a module you’re using is attempting to use an algorithm or key size which is no longer allowed by default with OpenSSL 3.0. A command-line option, --openssl-legacy-provider, has been added to revert to the legacy provider as a temporary workaround for these tightened restrictions.

For details about all the features in OpenSSL 3.0 please see the OpenSSL 3.0 release blog.

V8 9.5

The V8 JavaScript engine is updated to V8 9.5. This release comes with additional supported types for the Intl.DisplayNames API and Extended timeZoneName options in the Intl.DateTimeFormat API.

You can read more details in the V8 9.5 release post -

Readline Promise API

The readline module provides an interface for reading data from a Readable stream (such as process.stdin) one line at a time.

The following simple example illustrates the basic use of the readline module:

import * as readline from 'node:readline/promises';
import { stdin as input, stdout as output } from 'process';

const rl = readline.createInterface({ input, output });

const answer = await rl.question('What do you think of Node.js? ');

console.log(`Thank you for your valuable feedback: ${answer}`);
