     * This method keeps the invariant that the version of a child is bigger than the version of the parent.
     * This is because modifying the parent implies that all of its children have been modified, so they need to have at least the same version.
     *
     * @param newVersion The new version. Must be bigger than the current maximum version in this hierarchy.

## Dependencies для группы *операций путей*

Позже, читая о том как структурировать большие приложения ([Bigger Applications - Multiple Files](../../tutorial/bigger-applications.md){.internal-link target=_blank}), возможно, многофайловые, вы узнаете как объявить единый параметр `dependencies` для всей группы *операций путей*.
