Some of the improvements in the release include the following:
1. The Static Optimization tool now has better error handling and 
error messages. It is also compatible with models that have passive 
elements.
2. We created a new example demonstrating how to understand and 
improve the results of a Static Optimization analysis. 
3. The Scale tool now handles the scaling of ligaments.
We created a new script to help generate a reserve and residual 
actuator file for use with RRA, CMC, or Static Optimization.
4. Several bug fixes based on reports from our users.
