This file documents problems you may encounter when upgrading django-treebeard (potential backward incompatible changes). 20081117: Cleaned __init__.py, if you need Node you'll have to call it from it's original location (treebeard.models.Node instead of treebeard.Node). Also exceptions have been moved to treebeard.exceptions. 20100316: Queryset ordering in NS/MP trees is now enforced by the library. Previous ordering settings in META no longer work.
