Dear Colleagues: Version 2.0.5a5 of the OOF program for microstructure modeling is now available at http://www.ctcms.nist.gov/oof/oof2/ This version fixes a number of bugs, including some serious memory leaks. If you had problems with earlier versions running out of memory, especially during Skeleton modification, please try the new version. As before, this version is only called an "alpha" release because it includes some incomplete or untested new features, particularly interface properties. Upgrading to 2.0.5a5 is recommended for all OOF2 users. Sincerely, The OOF Team
