Node.js 22 LTS is now generally available for builds and functions

Starting today, Node.js version 22 is available as the runtime for your builds and functions leveraging Node. To use version 22, go to Project Settings > General > Node.js Version and select 22.x. This is also the default version for new projects.

Node.js 22 highlights:

• Improved Stream performance: higher default water mark provides performance boosts across the board at the cost of slightly higher memory usage

• Improved AbortSignal performance: optimized AbortSignal creation improves performance in fetch and the test runner

• Improved Buffer performance: significant improvements to the Buffer.copy and Buffer.write methods lead to overall performance boost

• Improved CJS interop with ESM: added support for require()ing synchronous ESM module graphs

The current version used by Vercel is 22.11.0 and will automatically update minor and patch releases. Therefore, only the major version (22.x) is guaranteed.
