"The STI Pub Group is delighted to announce the beta test release of the STIX Fonts in OpenType format. This release includes every glyph that is planned for the final, production release which we hope will follow before the end of the year. The beta test period will run from 1 November through 15 December. Regrettably, this beta test will not include TeX support. We expect the TeX package to be ready for beta test near the end of this year.
No amount of careful planning will ever replace dumb luck.
