Soar 9.6.0 is the current, stable version of Soar. It is the first major release in a few years and includes six key new features and hundreds of important bug fixes and code improvements:
  1. Explanation-Based Chunking: The first official release of a new, far more powerful rule learning algorithm that replaces chunking, Soar's original general learning mechanism
  2. Instance-based model of semantic memory: Can be used in a greater variety of ways and integrates with other aspects of Soar much more cleanly
  3. Streamlined user interface: Has far fewer top-level commands with improved presentation and feedback
  4. Explanations: A new explain command provides interactive exploration of an agent's rule learning experiences
  5. Visualizations: A new visualize command creates graphical representations of Soar's memory systems and even some of its processing
  6. Spreading activation: The first beta release of a model of spreading activation in semantic memory
