Alex certainly knows more about this, but here are a couple of things 
that I remember:

* revamped help patches (standardized structure + hyperlinks)

* different styles for audio/control inlets/outlets

* different/better font size handling

* the [import] object

* the libdir system (*-meta.pd files), although I don't know how it 
worked in practice

* different dragging behavior in graphical arrays
