-  Pymunk 6.5?
+Pymunk 6.5.0 (2023-06-23)
+-------------------------
+
+**Repeatable pickle/unpickle of simulation!**
+
+When pickling the internal collision state will now be pickled as well, 
+meaning that the unpickled space will behave as the original even when
+collisions where ongoing while pickling. This is useful if you want to 
+replay a simulation.
