Dear OOF Users -- A new version of OOF3D is now available at http://www.ctcms.nist.gov/oof/oof3d This version fixes a number of bugs in version 3.0.0, the most serious of which was an error in the calculation of element shape quality. The fix means that most skeleton modification routines will give quantitatively (but not qualitatively) different results in 3.0.1 than in 3.0.0. A full list of changes is at http://www.ctcms.nist.gov/oof/oof3d/changes.html. Please send bug reports to oof_bugs@nist.gov and other feedback to oof_manager@nist.gov. All comments are welcome! We especially like to receive copies of papers containing OOF calculations, for any version of OOF. This helps us to justify further development. Sincerely, Steve Langer Yannick Congo Andrew Reid Gunay Dogan
