Version 1.9.1

The GAMA development team is pleased to announce the release of GAMA 1.9.1

This version, while maintaining the power, stability, expressiveness and ease of use of GAMA, brings new capabilities and openings to the platform, making it even more intuitive to use by modelers and even more versatile in terms of applications.

This major release of GAMA contains many new features and fixes, including:

• A much more fluid and powerful IDE, offering support for all the latest technologies, from HiDPI displays to JDK 17 and Apple Silicon processors.
• A new server mode of GAMA, offering a clear and extensible exchange protocol, which completely revolutionizes the way to interact with the platform from R, Python or any web client.
• Increased model exploration possibilities thanks to new calibration and optimization methods, also directly usable in the server mode.
• The addition of the two new data types field and image, which make it even easier to load, analyze, visualize and produce raster data
• A much more powerful graph manipulation than previous versions, but still easy to couple with agents
• A focus on urban mobility applications, with the advanced_driving and pedestrian skills, which make it much easier to produce realistic large-scale mobility models.
• The possibility to simulate physical interactions between agents thanks to the new skills static_body, dynamic_body and physical_simulation, which rely on the native bullet library.
• New and faster display capabilities, offering more intuitive handling of agents and organisation of display surfaces, making it easier than ever to build interactive simulations, serious games or advanced scientific visualisations.
