### StackReference Breaking Change
StackReferences Identifier is Nullable now when the specified parser is not available (e.g. when a third-party plugin isn't available), or the parser fails to parse the item.
To reflect those changes, the `StackReference#identifier()` returns an `Optional` instead, and you may fall back to `StackReference#originalStack` when it is not present.
