OmniGraffle 5.3.1 is now available for download
 

[B]IMPORTANT[/B]: The Mac App Store version has not been released yet, it has been submitted for review — This release is mostly for the benefit of our users who are still running under Mac OS X v10.5.x.

We've managed to correct two very nasty crashes-on-launch for our Mac OS X v10.5 users along with fixing a few other bugs concerning stencils and exporting, etc.

You can find the latest disk images at our [URL="http://www.omnigroup.com/products/omnigraffle/download/"]Downloads page[/URL], and as always, you can peruse the voluminous [URL="http://www.omnigroup.com/products/omnigraffle/download/releasenotes/"]historical release notes[/URL] at your own peril.
