# Upgrade notes

> If you are using Design Atoms older than 5.31 and would like to upgrade to the later, note that a number of breaking changes were made

## Upgrading to 5.31 and above

#### Installing a Separate Model Package

In Customer's Canvas 5.31, the object model was separated from the `@aurigma/design-atoms` package. To rebuild your application, you must additionally install the new package:

```shell
npm install @aurigma/design-atoms-model --save
```

After that, replace imports `@aurigma/design-atoms/Model/<class>` with `@aurigma/design-atoms-model/<class>` in your .ts code.
