v2.1.0

  • Adds manipulate to manipulate outputs with plots
  • Adds mexport and mimport to model, which allow for exporting and importing models to .js and .json files.
  • Adds version locking to the dependencies. This prevents users from installing incompatible releases when installing the package.

v2.0.0 - LTS

  • Stochastic modelling,
  • Custom models in com module,
  • New pre-built compartments for you to use in comp, including:
    • Susceptible,
    • Exposed,
    • Infected,
    • Hospitalized,
    • Critical,
    • Recovered,
    • Dead,
    • and Vaccinated compartments,
  • A new utils compartment, which has epidemiological related utilities,
  • Bug fixes,
  • Customizable plotting, with the plots module,
  • Allows for more interaction with data from pre module,
  • And metadata on the web, through EpiJS.about, EpiJS.version, etc.

What makes this a major release?

This release is a major release for 2 reasons:

  • Drops 10.x support
  • Syntax for functions/classes was changed with stochastic models
  • pre module no longer outputs graphs, and is instead replaced with the plots module for graphs.

This release is also an LTS release, so bug fixes and security fixes for a while now.
