## [Prerelease] - Unreleased

## [v0.19.0] - 2026-11-04

### Added
* `Sandbox::snapshot_with_options` takes a snapshot with `SnapshotOptions`. `SnapshotOptions::scratch_size` gives the sandbox, and later restores of the snapshot, a different scratch size. A guest can boot with the scratch its initialisation needs and run guest function calls from a snapshot with only the scratch they need, so each restore costs less. It can also give a guest more scratch than it booted with.
* `Sandbox::scratch_allocated_bytes` returns how much scratch the guest has allocated since the sandbox was last restored or snapshotted. The guest controls the value it is read from.
