Node.js 24 Released: The 'Krypton' LTS Line Begins

Node.js 24 was first released on May 6, 2025 and carries the codename 'Krypton'. As an even-numbered major version, it follows the release line that historically becomes Active LTS, meaning it is the version the project steers production applications toward once it reaches that phase.

How Node.js releases work

Every major Node.js version starts in a Current phase that lasts about six months, giving library authors time to add support. Historically, up to Node.js 26, odd-numbered releases become unsupported after that six-month window, while even-numbered releases move into Active LTS. LTS, or long-term support, typically guarantees that critical bugs are fixed for a total of about 30 months, which is why the project advises production applications to run Active or Maintenance LTS releases rather than the newest Current line.

Why the LTS line matters

For teams shipping software, the practical takeaway is straightforward: an even-numbered release like Node.js 24 is the version to standardise on for production, because it will receive a long window of bug and security fixes. The Current line is where new features land first, but it is better suited to experimentation and preparing libraries than to running critical services.

A changing cadence ahead

The Node.js project has signalled a shift starting with Node.js 27: the release cycle will become annual, and every major version will move to LTS after its six-month Current phase. That change simplifies the odd-versus-even distinction that has guided upgrade decisions for years, but for Node.js 24 the familiar even-numbered LTS path applies.

What to do

Teams already on an older LTS such as Node.js 20 or 22 can plan a move to Node.js 24 once it is in Active LTS and their dependencies support it. As with any runtime upgrade, testing against the new version in a staging environment before rolling it into production is the safe path.
