 - `InteractionGroups` default value for `memberships` is now `GROUP_1` (#706)
 - `ImpulseJointSet::get_mut` has a new parameter `wake_up: bool`, to wake up connected bodies.
+- Removed unmaintained `instant` in favor of `web-time`. This effectively removes the `wasm-bindgen` transitive dependency as it's no longer needed.
