Climate Interactive updates the En-ROADS simulator on regular basis. Normally the reasons for updates include:


1. Update with the latest science - Climate Interactive monitors the latest climate science, economic projections, and other important sources of data that are used in the model. We update the model as new science and data become clear and vetted.


2. New features - The application and user interface are updated with new features, graphs, language translation, and sliders.


3. Fix errors - Sometimes there are errors/bugs in the software, and we work hard to discover and correct them quickly.


The update history of En-ROADS can be found in the User Guide here.
