Kaleidoscope is one of the world’s best tools for spotting differences in images and text. Now it supports the ignoring of leading, trailing and line-ending whitespace too. Kaleidoscope integrates directly with Git, Subversion, Mercurial, P4, and Bazaar to fit perfectly in your workflow.

The real question is does it still skin OS9.
I have an old piece of equipment in one of my labs attached to a Mac that is running OS9. I still have Kaleidoscope running on there and I switch up the windows now and then for old time’s sake.
