* Add `PickedInstancesCount` and `SceneInstancesCount` expressions, to replace `Count`. These expressions don't do any "picking" of instances, so they are safe to use anywhere without "weird" side effects. * Equivalent conditions are available for all objects. These conditions allow to check at any point in your events the number of instances living on the scene or picked by actions/conditions. * This is useful to check if enough objects are picked by a condition before launching an action. * Because this condition does not change the already picked objects, it's safe to use anywhere without any side effect. Only show the rest in the developer changelog: * Allow to read events missing some fields (like `disabled`, `folded`). * Reduce the useless information stored in project JSON files by not storing the fields if they have their default value.
