Hot on the heels of the release of OmniGraffle 5.0.2, here comes the first beta release of OmniGraffle 5.1.
Lots and lots of bug fixes, and some new features to pique your interest – Our Visio import support now includes Enhanced MetaFiles, we've finagled with the interface of the sidebars a fair bit to try and maintain focus in the main canvas area as much as possible, and added a new smart shape for making pie chart/arc/wedge type shapes.
Copious release notes and the beta disk images are available at the OmniGraffle beta page.
