+### [Rapier]
+
+[![Rapier logo](rapier-logo.svg)][Rapier]
+
+[Rapier] is a set of 2D and 3D physics engines for games, animation and
+robotics written in Rust.
+
+[This month][rapier-october] the version 0.3.0 has been released with exciting
+new features:
+
+- cylinders and cones as collider shapes;
+- collision groups (with bit masks) and collision filters (with callbacks)
+  for deciding what pairs of colliders can touch;
+- the ability to set the mass of rigid-bodies explicitly;
+- linear and angular damping, to progressively slow down rigid-bodies;
+- the ability so attach some user-defined data (of type `u128`) to any
+  collider or rigid-body.
+
+[![Rapier features](rapier-demo.gif)][rapier-demo]
+
+The [bevy_rapier] plugin for the Bevy game engine has been updated to support
+all the aforementioned features.
+
+Finally, a [continuous benchmarking][cont-bench] infrastructure has been set
+up to make sure performances regressions can be detected early.
