Vensim 9.3 fixes many issues and introduces some new functionality.
Action recorder (DSS only)
Vensim will now record your simulation actions to a command script so that you can re-run them later. You can access this new tool (and settings) under the Tools->Action recorder menu.
Syntax error panel
Vensim now reports errors in an easier-to-use panel. Check the model to view the new syntax error panel. Double-clicking navigates to the problem element in most cases.
