This binary release includes a variety of goodies. A few small bugs have been squashed. The functions rvectorize and cvectorize have been implemented. Both of these functions generate a column vector: rvectorize traverses matrices by row, and cvectorize traverses matrices by column.
We've written a test system that allows us to execute all the example code included in the OpenMx user guide. As a result of this system, we have caught all the syntax errors that were hiding in the user guide. Sorry about that. Please continue to be vigilant and post to the forums if you find a semantic error in the user guide. There is a new OpenMx style guide to help you write your scripts.
A preview of what is to come: we are simplifying the user interface for full information maximum likelihood with ordinal data. In OpenMx version 0.3.0, we will only support a single MxMatrix or MxAlgebra for specifying thresholds. If you are currently using multiple matrices/algebras to specify your thresholds, and you have any questions about the transition, please post to the forums.
