# v2.2.0

- Add `.remove` and `.add` functions to `Model` class in `model` module to add and remove compartments.

# v2.1.2

- Fix error from previous release

# v2.1.1

- Fix key error in `model`

# 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.
