Notable Changes

This release marks the transition of Node.js 24.x into Long Term Support (LTS) with the codename ‘Krypton’. It will continue to receive updates through to the end of April 2028.

Other than updating metadata, such as the process.release object, to reflect that the release is LTS, no further changes from Node.js 24.10.0 are included.

Known issue

An issue has been identified in the Node.js 24.x line with Buffer.allocUnsafe unintentionally returning zero-filled buffers. This API is documented to return uninitialized memory. The documented behavior will be restored in the next Node.js 24.x LTS release to bring it back in line with previous releases. For more information, see #60423.

Commits

• [a71dd592e3] - benchmark: calibrate config dgram multi-buffer (Bruno Rodrigues) #59696

Node.js 25 is here! We have upgraded V8 to 14.1, bringing major JSON.stringify performance improvements, built-in Uint8Array base64/hex conversion, and ongoing WebAssembly and JIT pipeline optimizations.

This release doubles down on secure-by-default apps and web-standard APIs: the permission model gains --allow-net, Web Storage is enabled by default, and ErrorEvent is now a global.

We’ve also removed or finalized long-deprecated APIs such as SlowBuffer, and added quality-of-life improvements like a portable compile cache and JSPI for WebAssembly.

Notable Changes

OpenSSL updated to 3.5.2

For official Node.js builds, or builds using the default build configuration, Node.js now bundles OpenSSL 3.5.2. This update allows Node.js 22.x to be supported through to the planned End-of-Life date of 2027-04-30 as the previously bundled OpenSSL 3.0.x goes out of support in September 2026.

This change does not affect third-party builds of Node.js that link to an external OpenSSL (or OpenSSL-compatible) library.

Notable Changes

HTTP/2 Network Inspection Support in Node.js

Node.js now supports inspection of HTTP/2 network calls in Chrome DevTools for Node.js.

Usage

Write a test.js script that makes HTTP/2 requests.

const http2 = require('node:http2');

const client = http2.connect('https://nghttp2.org');

const req = client.request([
  ':path', '/',
  ':method', 'GET',
]);

Run it with these options:

node --inspect-wait --experimental-network-inspection test.js

Open about:inspect on Google Chrome and click on Open dedicated DevTools for Node. The Network tab will let you track your HTTP/2 calls.

Notable Changes

Post-Quantum Cryptography in node:crypto

OpenSSL 3.5 on 24.x kicked off post-quantum cryptography efforts in Node.js by allowing use of NIST’s post-quantum cryptography standards for future-proofing applications against quantum computing threats. The following post-quantum algorithms are now available in node:crypto:

• ML-KEM (FIPS 203, Module-Lattice-Based Key-Encapsulation Mechanism Standard) through new crypto.encapsulate() and crypto.decapsulate() methods.
• ML-DSA (FIPS 204, Module-Lattice-Based Digital Signature Standard) in the existing crypto.sign() and crypto.verify() methods.

Contributed by Filip Skokan in #59259 and #59491.

Modern Algorithms in Web Cryptography API

The second substantial extension to the Web Cryptography API (globalThis.crypto.subtle) was recently accepted for incubation by WICG. The following algorithms and methods from this extension are now available in the Node.js Web Cryptography API implementation:

• AES-OCB
• ChaCha20-Poly1305
• ML-DSA
• ML-KEM
• SHA-3
• SHAKE
• subtle.getPublicKey()
• SubtleCrypto.supports()
• … with more coming in future releases.

Notable Changes

Upgrade to OpenSSL 3.5

This release is distributed with OpenSSL 3.5.1, following the announcement that OpenSSL 3.5 will be supported until April 2030, while Node.js 24 will be supported until April 2028. Read more about OpenSSL support in their blog post: https://openssl-library.org/post/2025-02-20-openssl-3.5-lts/.

Contributed by Richard Lau in #58100.

Unflag --experimental-wasm-modules

Node.js supports both source phase imports and instance phase imports to WebAssembly modules and for WASM imports to JavaScript, in line with the current Phase 3 WebAssembly ESM Integration proposal. The implementation and the specification are still subject to change.

Contributed by Guy Bedford in #57038.

Built-in proxy support in request() and Agent

node:http and node:https now support proxies. When NODE_USE_ENV_PROXY is set to 1, the default global agent would parse the http_proxy/HTTP_PROXY, https_proxy/HTTPS_PROXY, no_proxy/NO_PROXY settings from the environment variables, and proxy the requests sent through the built-in http/https client accordingly.

To use global proxy support from the command line:

NODE_USE_ENV_PROXY=1 HTTP_PROXY=http://proxy.example.com:8080 HTTPS_PROXY=http://proxy.example.com:8080 NO_PROXY=localhost,127.0.0.1 node client.js

Notable Changes

Type stripping is enabled by default

Node.js will be able to execute TypeScript files without additional configuration:

$ echo 'const foo: string = 'World'; console.log(`Hello ${foo}!`);' > file.ts
$ node file.ts
Hello World!

There are some limitations in the supported syntax documented at https://nodejs.org/api/typescript.html#type-stripping.

This feature is experimental and is subject to change. Disable it by passing --no-experimental-strip-types CLI flag.

Notable Changes

⚠️ Deprecations

Instantiating node:http classes without new

Constructing classes like IncomingMessage or ServerResponse without the new keyword is now discouraged. This clarifies API expectations and aligns with standard JavaScript behavior. It may warn or error in future versions.

Contributed by Yagiz Nizipli in #58518.

options.shell = "" in node:child_process

Using an empty string for shell previously had undefined behavior. This change encourages explicit choices (e.g., shell: true or a shell path) and avoids relying on implementation quirks.

Contributed by Antoine du Hamel and Renegade334 #58564.

HTTP/2 priority signaling

The HTTP/2 prioritization API (e.g., stream.priority) is now deprecated due to poor real-world support. Applications should avoid using priority hints and expect future removal.

Contributed by Matteo Collina and Antoine du Hamel #58313.

✅ Features graduated to stable

assert.partialDeepStrictEqual()

This method compares only a subset of properties in deep object comparisons, useful for flexible test assertions. Its stabilization means it’s now safe for general use and won’t change unexpectedly in future releases.

Contributed by Ruben Bridgewater in #57370.

Notable Changes

Remove support for HTTP/2 priority signaling

The support for priority signaling has been removed in nghttp2, following its deprecation in the RFC 9113. As a consequence of this, priority signaling is deprecated on all release lines of Node.js, and removed from Node.js 24 so we can include latest updates from nghttp2.

Contributed by Matteo Collina and Antoine du Hamel in #58293.

import.meta.main is now available

Boolean value available in ECMAScript modules, which can be used to detect whether the current module was the entry point of the current process.

export function foo() {
  return 'Hello, world';
}

function main() {
  const message = foo();
  console.log(message);
}

if (import.meta.main) main();
// `foo` can be imported from another module without possible side-effects from `main`

Starting with Node.js 24, support for MSVC has been removed, and ClangCL is now required to compile Node.js on Windows. The AsyncLocalStorage API now uses AsyncContextFrame by default, and URLPattern is available globally. These changes, along with many other improvements, continue to push the platform forward.

As a reminder, Node.js 24 will enter long-term support (LTS) in October, but until then, it will be the “Current” release for the next six months. We encourage you to explore the new features and benefits offered by this latest release and evaluate their potential impact on your applications.

Notable Changes

V8 13.6

The V8 engine is updated to version 13.6, which includes several new JavaScript features:

• Float16Array
• Explicit resource management
• RegExp.escape
• WebAssembly Memory64
• Error.isError

The V8 update was a contribution by Michaël Zasso in #58070.

Notable Changes

Introducing --experimental-config-file

With the introduction of test runner, SEA, and other feature that require a lot of flags, a JSON config flag would improve by a lot the developer experience and increase adoption.

You can have a node.config.json containing:

{
  "$schema": "https://nodejs.org/dist/v23.10.0/docs/node-config-schema.json",
  "nodeOptions": {
    "test-coverage-lines": 80,
    "test-coverage-branches": 60
  }
}

You can run your tests without passing the flags defined in the config file.

node --experimental-default-config-file --test --experimental-test-coverage

or

node --experimental-config-file=node.config.json --test --experimental-test-coverage

Node.js will not sanitize or perform validation on the user-provided configuration, so only ever use trusted configuration files.

• [6fd2ec6816] - doc: add @geeksilva97 to collaborators (Edy Silva) #57241

Notable Changes

require(esm) is now enabled by default

Support for loading native ES modules using require() had been available on v20.x under the command line flag –experimental-require-module, and available by default on v22.x and v23.x. In this release, it is now no longer behind a flag on v20.x.

This feature has been tested on v23.x and v22.x, and we are looking for user feedback from v20.x to make more final tweaks before fully stabilizing it. It now no longer emits a warning unless --trace-require-module is explicitly used. If there happens to be any regressions caused by this feature, users can report it to the Node.js issue tracker. Meanwhile this feature can also be disabled using --no-experimental-require-module as a workaround.

With this feature enabled, Node.js will no longer throw ERR_REQUIRE_ESM if require() is used to load a ES module. It can, however, throw ERR_REQUIRE_ASYNC_MODULE if the ES module being loaded or its dependencies contain top-level await. When the ES module is loaded successfully by require(), the returned object will either be a ES module namespace object similar to what’s returned by import(), or what gets exported as "module.exports" in the ES module.

Notable Changes

Support for using system CA certificates store on macOS and Windows

This version adds the --use-system-ca command-line flag, which instructs Node.js to use the trusted CA certificates present in the system store along with the --use-bundled-ca, --use-openssl-ca options.

This option is available on macOS and Windows for now.

Contributed by Tim Jacomb in #56599 and Joyee Cheung in #56833.

Introduction of the URL Pattern API

An implementation of the URL Pattern API is now available.

The URLPattern constructor is exported from the node:url module and will be available as a global in Node.js 24.

Contributed by Yagiz Nizipli and Daniel Lemire in #56452.

Support for the zstd compression algorithm

Node.js now includes support for the Zstandard (zstd) compression algorithm. Various APIs have been added to the node:zlib module for both compression and decompression of zstd streams.

Contributed by Jan Krems in #52100.

Node.js thread names

Threads created by the Node.js process are now named to improve the debugging experience. Worker threads will use the name option that can be passed to the Worker constructor.
