- Use `NOTIFICATION_ENTER`/`EXIT_WORLD` for `Area` (intead of `*_TREE`). - Now both bodies' and areas' constraints are cleaned up. - And now also that happens as soon as the space is set to null (i.e., when exiting the tree) instead of only at freeing time. - When clearing constraints, the loop goes on to the next if the current is already released, instead of breaking. - When one has been already released, no error is shown from now on, as it's something expected, since a pair (our kind of constraint of interest) can be freed by any of its involved collision objects and the other will try again. - Implement index shifting (or marking as -1) for shapes indices in collision pairs shapes are removed. - Standarize behavior of bodies and areas so that anything that invalidates a given pair gives the same result (collision mask, actual collision, etc); for instance, triggering area enter/exit signals. - Add missing member initializations. - Extend the new-space-equals-area/body-current-space test to every case. - Fix 3D ray-casts early accepting Areas (skipping the mask check). - Fix unpairing of large elements (2D's `BroadPhase2DHashGrid`). Some of these prevent random crashes caused by constraints with dangling pointers to involved objects. Fixes #8856. Fixes #7589. Fixes #6676. And maybe others.
