Closure Tree v4.0.0 Release Notes

    • 🚚 Moved all of closure_tree's implementation-detail methods into a ClosureTree::Support instance, which removes almost all of the namespace pollution in your models that wasn't for normal consumption. If you were using any of these methods, they're now available through the "_ct" class and instance member.

    This change may break consumers, so I incremented the major version number, even though no new functionality was released.
