reactstrap: Spinner is not exported from 'reactstrap'

• components: Spinner
• reactstrap version 7.0.2
• import method umd/csj/es
• react version 6.7.0
• bootstrap version 4.2.1

What is happening?

I do

import { Spinner } from 'reactstrap';

and use it in render method like

<Spinner color="primary" /> according to the doc https://reactstrap.github.io/components/spinners/

What should be happening?

I expected view the Spinner component.

I checked node_modules/reactstrap/src/index.js but Spinner is not exported.

Steps to reproduce issue

1. setup reactstrap
2. in any component, do import { Spinner } from 'reactstrap';

Error message in console

./src/Auth/Components/SignupForm.js
Attempted import error: 'Spinner' is not exported from 'reactstrap'.

Code

import { Spinner } from 'reactstrap';
