There may not be any compatiblity problems if you continue to use code
compilied under MPW 2.x. What you will run into is that MPW 2.x will not
run under System 7.0 or A/UX. MPW 3.x comes with several nice additions
as well. Projector, the Mark Browser, split text views to name a few. Of
these Projector is the most useful.
