Typography component was removed in version 4, for more information, see the detailed migration guide.
The main reason for this component was to maintain the spacing between typography components. In version 4 we gave this possibility to each, individual typography component.
Right now instead of wrapping your typography in
Typography component, you can just set margin value to each individual typography components.
You might have used
Typography in version 3 like that:
<Typography><Heading element="h4" className="className">Some text</Heading></Typography>
All you need to do is to use this components directly, without a wrapper:
<Heading as="h4" className="className">Some text</Heading>
