what is the last Mac Tiger or Leopard PPC (not Intel) compatible version?

Hi, I have the older cover mounted free version, 2.2 I think. I see the latest is 3.2 and Intel only on the Mac. So rather than buy a new Mac can I download the final release for this PPC platform?

Cheers

2.6.1 is the last version compatible with PPC. (There wasn't a version 2.2, maybe you mean 2.1.)
