The major changes are: use of jQuery’s native “live” method instead of listen plugin; rewritten drag events; onselect/ondeselect callbacks; no more leakage to global namespace ($.tree_create() repaces new tree_component()); minimized usage of float ... [More] (inline-block is used instead); apple theme included and checkbox theme included (with optional onchange callback, which emulates tri-state checkboxes); no more hardcoded background; smarter drop location calculation.
