React - Is there is a difference between TransitionGroup / ReactCSSTransitionGroup / CSSTransitionGroup

Question

So I cannot figure out why people like to call the React Transition Functions in the different ways by

TransitionGroup: import TransitionGroup from 'react-transition-group/TransitionGroup'

ReactCSSTransitionGroup import ReactCSSTransitionGroup from 'react-transition-group'

CSSTransitionGroup import CSSTransitionGroup from 'react-transition-group/CSSTransitionGroup'

So, the question is there some differenses (performance, functionality) between these invokes or it just on the mind of the developer - how to call the Transition from react-transition-group...

P.S. I do not find the answer on this question in the web.

I'll be pleased for any help...

Based on the index.js the following are the same:

import { TransitionGroup } from 'react-transition-group'
import TransitionGroup from 'react-transition-group/TransitionGroup'

The since CSSTransition exports a default class the following is misleading:

import TransitionGroup from 'react-transition-group/CSSTransition'
import AnyThing from 'react-transition-group/CSSTransition'
