**Other features**

- **Root disk resizing in every SDK.** The TypeScript, Python, and Go SDKs now expose `rootDiskSize` / `root_disk_size` / `RootDiskSizeMiB` on `modify()`, mapped to the canonical `root_disk_size_mib` patch field. Restart and next-start semantics and backing-specific limits are documented in the [Live Modify guide](/sandboxes/tuning).
- **Active backend context.** New `default_backend_info()` / `defaultBackendInfo()` accessors, and per-sandbox `backendKind` / `backend_kind` fields, let applications inspect the resolved default backend, its cloud API URL, the selector that chose it, and its profile. The API key is never included. A new `msb context` command prints the same information, and `create`, `remove`, `exec`, and `ssh` show a short backend notice. Invalid cloud CLI configuration now fails closed instead of silently dispatching locally. See [backends](/getting-started/backends).

- **Go SDK: attach as non-default guest users.** The Go SDK gains `AttachWith`, with `WithAttachUser`, `WithAttachCwd`, `WithAttachEnv`, and `WithAttachDetachKeys`, matching the Python and TypeScript surface. The existing `Attach` API is unchanged. See the [Go SDK reference](/sdk/go/execution).

- **Explicit cloud backend selection is now required.** Setting `MSB_API_KEY` alone no longer selects the cloud. Cloud intent must be declared through `MSB_BACKEND=cloud`, a selected cloud profile, or a programmatic backend setter. Invalid cloud configuration returns `InvalidConfig` instead of falling back to local execution. See [backends](/getting-started/backends).
