  • The correct ordering in NS/MP trees is now enforced in the queryset.

  • Fixed support of trees using proxied models. It was broken due to a bug in Django.
  • Fixed a bug in add_child when adding nodes to a non-leaf in sorted MP.

  • This will be the last version compatible with Django 1.0. There will be a a 1.6.X branch maintained for urgent bug fixes, but the main development will focus on recent Django versions.
