Vercel Sandbox now runs Node.js 26. The update is available in @vercel/sandbox version 1.10.2 or later for v1 users, and version 2.0.0-beta.19 or later for v2 users.
To activate it on v2, set the runtime property to node26. That single config change is the entire migration path.
The changelog entry is brief, but the SDK reference documentation is where the real detail lives. If you are evaluating Vercel Sandbox for production workloads, the versioning model and runtime options are worth reading in full before committing.
