+
+[bevy_xpbd] by [@Jondolf] is a 2D and 3D physics engine based on
+Extended Position Based Dynamics for the Bevy game engine.
+It uses Bevy's Entity Component System (ECS) directly for the simulation data
+and logic, which makes the design and API feel better integrated into Bevy while
+avoiding the overhead associated with copying lots of data to a separate data
+structure like in many other physics engines such as bevy_rapier.
+
+In mid-July, bevy_xpbd 0.2 was released, featuring:
+
+- Spatial queries (ray casting, shape casting, point projection, intersection tests);
+- Bevy 0.11 support;
+- Improved scheduling;
+- Velocity damping;
+- Gravity scale;
+- Locking translational and rotational axes;
+
+and much more. You can find more details in the
+[release post][bevy-xpbd-post] and [changelog][bevy-xpbd-changelog].
+
+A lot of work was also done during the rest of July. The physics debug renderer
+was improved, collision stability issues were significantly reduced, external
+impulses were added, and Bevy's own `Transform`s can now be used directly
+for moving bodies. The narrow phase part of collision detection was also
+refactored into a separate plugin, which makes multithreading and several
+upcoming features much easier to implement while also improving modularity.
