 * **Breaking:** Filesystem paths are now represented using `PathBuf`. `GuestBinary::FilePath` now stores a `PathBuf` instead of a `String`, and `MultiUseSandbox::generate_crashdump_to_dir` accepts `Into<PathBuf>` instead of `Into<String>`. Callers passing a `String` to `GuestBinary::FilePath` must convert it using `.into()`.
 * Deprecate `MultiUseSandbox::poisoned` in favor of `MultiUseSandbox::status().is_poisoned()`.
+* `MultiUseSandbox::restore` has been made more flexible and now accepts snapshots from any guest binary or memory layout when host functions are compatible.
