An OrderedSet is a custom MutableSet that remembers its order, so that every entry has an index that can be looked up. It combines the uniqueness of a set with the order-preserving and indexable properties of a list. The library is currently at version 4.1.0 and is actively maintained, with updates driven by new features and bug fixes.
