Node.js 24.15.0 LTS released

Node.js 24.15.0 moved into long-term support on April 15, giving the 24.x line a production-focused release with 30 months of support. (nodejs.org) Node.js is the JavaScript runtime that powers web servers, command-line tools, and build systems outside the browser. The Node.js project lists 24.15.0 as the latest long-term support release and labels it “Krypton.” (nodejs.org) The 24.15.0 release adds a new `--max-heap-size` command-line option, marks `require` support for ECMAScript modules as stable, and marks the module compile cache as stable. The release notes also list new file-system, Hypertext Transfer Protocol 2, networking, SQLite, and test-runner changes. (nodejs.org) Long-term support is Node’s stability track for production deployments. The project says long-term support lines typically receive critical bug fixes for 30 months, and it recommends production applications use Active LTS or Maintenance LTS releases. (nodejs.org) That matters for teams that pin a Node version across application servers, continuous-integration pipelines, and local development machines. A long-term support designation signals that the 24.x branch is the one Node expects backend and full-stack JavaScript teams to standardize on for routine updates instead of chasing every current release. (nodejs.org) The archive page for v24.15.0 says the line was first released on May 6, 2025, and last updated on April 15, 2026. It also shows Node 24 ships with npm 11.12.1, V8 13.6.233.17, and N-API version 137. (nodejs.org) One security detail sits under the hood: the Node 24 changelog says the line is distributed with OpenSSL 3.5.1, and notes OpenSSL 3.5 support runs until April 2030 while Node 24 support runs until April 2028. That lines up the JavaScript runtime with a supported cryptography library for most of the branch’s life. (github.com) The Node.js project is also changing its broader cadence. In a March 2026 announcement, maintainers said that starting with 27.x, Node will move from two major releases a year to one, while saying users who already upgrade on long-term support should see little change beyond version numbering. (nodejs.org) For developers deciding what to deploy this spring, the signal is straightforward: Node 24 is now the supported long-haul branch, and 24.15.0 is the release the project is pointing them to first.
