+### [bevy_backroll v0.3][backroll-github]
+
+[Backroll][backroll-github] is a 100% type-safe native Rust implementation of the
+[GGPO][ggpo] rollback netcode library. The core library has gone through
+superfical updates, but the [Bevy plugin][bevy-backroll-crates-io] has been
+massively overhauled. This update signfigantly improves the ergonomics of setting
+up rollback netcode for your game (no more ugly turbofishes! no more generic type
+parameter config type!), provides an automatic way of saving and loading Bevy
+components and resources, and fully parallelizes the saving and loading of game
+state when a rollback occurs.
