June 1.1 This version is not backwards compatible with 1.0, which means that old config files and created Worlds won't work. Changelog Epidemiology related functionality is now all contained in the Epidemiology class and corresponding source folders. New Immunity class tracks the immunity related information of an agent, such as their susceptibility to infection. People can now be vaccinated with lots of customizable parameters. People can now be reinfected with virus variants, and have different susceptibilities to each of them. Added functionality to easily initialize the population with a certain vaccination rate and pre-infection status. New domain decomposition boosts the speed of the code when running in HPC clusters. Documentation The old documentation has been removed to avoid confusion as it is not up-to-date with the new version of the code. We plan to release the new docs soon.
