- **deprecated** — Deprecate the runtime option in the SDK and CLI
- **changed** — Change default sandbox image from node24 runtime on Amazon Linux 2023 to vercel/sandbox/universal based on Ubuntu with Node.js 24, Bun, Python 3.14, coding agents, and development tools
- **changed** — Passing both runtime and image parameters is now an error

###### Major Changes

- Add support for Vercel Managed Images and deprecate the `runtime` option in the SDK and CLI. Runtime-based creation remains supported through the legacy v2 API; image-based and default creation use the v3 API. Passing both `runtime` and `image` is an error. ([#276](https://github.com/vercel/sandbox/pull/276))

  Sandboxes that do not specify an image now use `vercel/sandbox/universal`. The previous default was the `node24` runtime on Amazon Linux 2023. The new default is based on Ubuntu and includes Node.js 24, Bun, Python 3.14, coding agents, and common development and debugging tools.

  Existing `runtime` calls continue to work, it's recommended to migrate to Vercel managed images when possible:

  - Not using `runtime`: omit `image` to use the new Universal image, or set `image: "vercel/sandbox/node:24"` for an Ubuntu-based Node.js equivalent to the previous default.
  - Using `runtime: "node22"`: use `image: "vercel/sandbox/node:22"` for an Ubuntu-based equivalent.
  - Using `runtime: "node24"`: use `image: "vercel/sandbox/node:24"` for an Ubuntu-based equivalent.
  - Using `runtime: "node26"`: use `image: "vercel/sandbox/node:26"` for an Ubuntu-based equivalent.
  - Using `runtime: "python3.13"`: use `image: "vercel/sandbox/python:3.14"` for an Ubuntu-based equivalent, and note the Python version upgrade.
