 ### Modified
-- Renamed `BodyStatus` to `RigidBodyType`.
+The use of `RigidBodySet, ColliderSet, RigidBody, Collider` is no longer mandatory. Rigid-bodies and colliders have
+been split into multiple components that can be stored in a user-defined set. This is useful for integrating Rapier
+with other engines (for example this allows use to use Bevy's Query as our rigid-body/collider sets).
 
-FIXME:
+The `RigidBodySet, ColliderSet, RigidBody, Collider` are still the best option for whoever doesn't want to
+provide their own component sets.
+
+#### Rigid-bodies
+- Renamed `BodyStatus` to `RigidBodyType`.
 - `RigidBodyBuilder::translation` now takes a vector instead of individual components.
 - `RigidBodyBuilder::linvel` now takes a vector instead of individual components.
+- The `RigidBodyBuilder::new_kinematic` has be replaced by the `RigidBodyBuilder::new_kinematic_position_based` and
+  `RigidBodyBuilder::new_kinematic_velocity_based` constructors.
+- The `RigidBodyType::Kinematic` variant has been replaced by two variants: `RigidBodyType::KinematicVelocityBased` and
+  `RigidBodyType::KinematicPositionBased`.
+  
+#### Colliders
 - `Colliderbuilder::translation` now takes a vector instead of individual components.
 - The way `PhysicsHooks` are enabled changed. Now, a physics hooks is executed if any of the two
   colliders involved in the contact/intersection pair contains the related `PhysicsHooksFlag`.
   These flags are configured on each collider with `ColliderBuilder::active_hooks`. As a result,
   there is no `PhysicsHooks::active_hooks` method any more.
+- All events are now disabled for all colliders by default. Enable events for specific colliders by setting its
+  `active_events` bit mask to `ActiveEvents::CONTACT_EVENTS` and/or `ActiveEvents::PROXIMITY_EVENTS`.
+- Add a simpler way of enabling collision-detection between colliders attached to two non-dynamic rigid-bodies: see
+  `ColliderBuilder::active_collision_types`.
+- The `InteractionGroups` is now a structures with two `u32` integers: one integers for the groups
+  membership and one for the group filter mask. (Before, both were only 16-bits wide, and were
+  packed into a single `u32`).
 - Before, sensor colliders had a default density  set to 0.0 whereas non-sensor colliders had a
   default density of 1.0. This has been unified by setting the default density to 1.0 for both
   sensor and non-sensor colliders.
 - Colliders are no longer required to be attached to a rigid-body. Therefore, `ColliderSet::insert`
   only takes the collider as argument now. In order to attach the collider to a rigid-body,
   (i.e., the old behavior of `ColliderSet::insert`), use `ColliderSet::insert_with_parent`.
-- The field `ContactPair::pair` (which contained two collider handles) has been replaced by two
+- Fixed a bug where collision groups were ignored by CCD.
-  fields: `ContactPair::collider1` and `ContactPair::collider2`.
+
+#### Joints
 - The fields `FixedJoint::local_anchor1` and `FixedJoint::local_anchor2` have been renamed to
   `FixedJoint::local_frame1` and `FixedJoint::local_frame2`.
+  
+#### Pipelines and others
+- The field `ContactPair::pair` (which contained two collider handles) has been replaced by two
+  fields: `ContactPair::collider1` and `ContactPair::collider2`.
 - The list of active dynamic bodies is no retrieved with `IslandManager::active_dynamic_bodies`
   instead of `RigidBodySet::iter_active_dynamic`.
 - The list of active kinematic bodies is no retrieved with `IslandManager::active_kinematic_bodies`
   instead of `RigidBodySet::iter_active_kinematic`.
-- The `InteractionGroups` is now a structures with two `u32` integers: one integers for the groups
-  membership and one for the group filter mask. (Before, both were only 16-bits wide, and were 
-  packed into a single `u32`).
 - `NarrowPhase::contacts_with` now returns an `impl Iterator<Item = &ContactPair>` instead of 
   an `Option<impl Iterator<Item = (ColliderHandle, ColliderHandle, &ContactPair)>>`. The colliders
   handles can be read from the contact-pair itself.
 - `NarrowPhase::intersections_with` now returns an iterator directly instead of an `Option<impl Iterator>`.
 - Rename `PhysicsHooksFlags` to `ActiveHooks`.
-- The `RigidBodyBuilder::new_kinematic` has be replaced by the `RigidBodyBuilder::new_kinematic_position_based` and
-  `RigidBodyBuilder::new_kinematic_velocity_based` constructors.
-- The `RigidBodyType::Kinematic` variant has been replaced by two variants: `RigidBodyType::KinematicVelocityBased` and
-  `RigidBodyType::KinematicPositionBased`.
-- Fixed a bug where collision groups were ignored by CCD.
 - Add the contact pair as an argument to `EventHandler::handle_contact_event`
-- All events are now disabled for all colliders by default. Enable events for specific colliders by setting its
+
-  `active_events` bit mask to `ActiveEvents::CONTACT_EVENTS` and/or `ActiveEvents::PROXIMITY_EVENTS`.
-- Add a simpler way of enabling collision-detection between colliders attached to two non-dynamic rigid-bodies: see
-  `ColliderBuilder::active_collision_types`.
