+### [Sparsey]
+
+[Sparsey] by [@LechintanTudor] is a sparse set-based Entity Component System
+(ECS) with component storage grouping, granular component change detection,
+fallible systems and beautiful syntax.
+
+The latest release (0.4) adds support for optional system parameters, which
+allows `Option<Res<T>>` and `Option<ResMut<T>>` to be used in system functions.
+
+This release also features a refactored `ComponentStorage` which makes adding,
+removing and swapping components faster, swapping being especially important
+since it enables component grouping, a features that makes certain queries
+specified by the user extremely fast.
+
+Finally, some implementation details were hidden from the public API and the
+`#[must_use]` attribute was added to functions whose results should not be
+discarded.
