Documentation

• Documentation is now available from the web (reference.wolfram.com/system-modeler)
• Dramatically improved documentation of built-in model libraries, including parameters, connections, links to examples, etc.
• Automatically generated documentation for models, packages, etc.
• WYSIWYG editing of embedded HTML documentation makes it easy to add professional-looking documentation to models
• Improved model and experiment publishing feature makes it easy to automatically publish your models, visualizations, etc.

Modeling

• Model browser is now divided into four sections: Examples, Libraries, User Classes, and Recently Used Components
• Faster browsing of model libraries and components
• Connections between components are now color-coded to indicate domains
• Automatically create hierarchical models by selecting components in the diagram view
• Easily drill into components in hierarchical models to configure them (set parameters, initial values, etc.)
• Interactive support for replaceable components, allowing reconfigurable models
• Annotations are now by default hidden in the Text View for improved readability

Simulation

• Improved visualization aesthetics with plot themes, grid styles, etc.
