Vercel now supports pnpm v10.

New projects with a `pnpm-lock.yaml` file with `lockfileVersion: '9.0'` will automatically use pnpm v10 for Install and Build Commands. Existing projects will continue to use pnpm v9 for backwards compatibility, since pnpm v9 also uses `lockfileVersion: '9.0'`.

Check your [build logs](https://vercel.com/docs/deployments/logs) to see which version a deployment uses. If you'd like to manually upgrade or downgrade your version, [use Corepack](https://vercel.com/docs/deployments/configure-a-build#corepack).

Visit the [package managers documentation](https://vercel.com/docs/deployments/builds/package-managers#supported-package-managers) to learn more.
