Highlights
Mesa 3.1.1 is a maintenance release that includes visualization improvements and documentation updates. The key enhancement is the addition of an interactive play interval control to the visualization interface, allowing users to dynamically adjust simulation speed between 1ms and 500ms through a slider in the Controls panel.
Several example models were updated to use Mesa 3.1's recommended practices, particularly the create_agents() method for more efficient agent creation and NumPy's rng.integers() for random number generation. The Sugarscape example was modernized to use PropertyLayers.
Bug fixes include improvements to PropertyLayer visualization and a correction to the Schelling model's neighbor similarity calculation. The tutorials were also updated to reflect current best practices in Mesa 3.1.
