After a beta testing period that got somewhat interrupted by WWDC and submitting OmniGraffle 1.2 for iPad to the App Store, we're happy to announce that the final versions of OmniGraffle and OmniGraffle Professional 5.2.3 are ready and available for download.
For those not following the beta releases, version 5.2.3 fixes some important bugs with respect to Bézier lines and how they connect to shapes, fixes some important issues when exporting to other formats, and adds file management options when exporting to various OmniGraffle formats to better get your files working on the iPad.
Find the disk images at our download page, and read up on the lengthy history of OmniGraffle at our historical release notes page.
