I'm just wondering if 4.2.2 marks the end of development of OmniGraffle/OmniGraffle Pro for Tiger (10.4.x) Mac users? I love the (Pro) program and use it all the time, but my hardware (admittedly old) limits me to Tiger, not Leopard. I know time moves forward, but I'm somewhat worried I won't see any new features as a Tiger user. Thanks for listening.
