2026-05-05, Version 26.0.0 (Current), @RafaelGSS

We're excited to announce the release of Node.js 26! Highlights include the Temporal API enabled by default,
updates to the V8 JavaScript engine to 14.6, Undici to 8.0, and several important deprecations and removals
as we continue to modernize the platform.

As a reminder, Node.js 26 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

Temporal API

The Temporal API is now enabled by default in Node.js 26. Temporal is a modern date/time API for JavaScript
that provides a more robust and feature-rich alternative to the legacy Date object.

Contributed by Richard Lau in #61806.

V8 14.6

The V8 engine is updated to version 14.6.202.33, which is part of Chromium 134.

This version also includes:

Upsert (https://github.com/tc39/proposal-upsert): [Weak]Map.prototype.getOrInsert(), [Weak]Map.prototype.getOrInsertComputed()
Iterator sequencing (https://github.com/tc39/proposal-iterator-sequencing): Iterator.concat()

Contributed by Michaël Zasso in #61898.

Undici 8

Undici has been updated to version 8.0.2, bringing new features and improvements to Node.js's HTTP client implementation.

🚀 New features to boost your workflow:

❄️ Test Analytics: Detect flaky tests, report on failures, and find test suite problems.
📦 JS Bundle Analysis: Save yourself from yourself by tracking and limiting bundle sizes in JS merges.

Blocking on V8 update (#61898) and #62533 (or some variation of it).

📦 https://ci-release.nodejs.org/job/iojs+release/11700/ + https://ci-release.nodejs.org/job/iojs+release/11707/ - RC.1 - Temporary V8 14.6 update.

Due to the issues we are having to land V8 14.6, I will postpone the v26 to the next week (28th). I can't land it in another day of this week since I'm traveling back to Brazil.

The issue description contains:

The V8 engine is updated to version 14.6.202.33, which is part of Chromium 134.

that ought to be Chromium 146 (per V8's release numbering scheme), I suppose?

This has remained incorrect in the release announcement.
