Slim/twig-view:3.0.0-beta doesn't include new Twig.php

I’ve been using Twig-View, and now testing Twig-View 3-beta with Slim 4.
Then PHP Fatal error occurs.
Uncaught Error: Call to undefined method Slim\Views\Twig::create()
This occurs when I download slim/twig-view:3.0.0-beta via Composer.
It doesn’t occurs if I download zip file via GitHub.
Actually slim/twig-view:3.0.0-beta package via composer doesn’t include new Twig.php file.

The latest master has support for Twig 3 now.

Not Twig 3.
Twig-View 3.

What happens when you install the latest dev version?

composer require slim/twig-view:"3.x-dev"

What happens when you install the latest dev version?

Oh!
This is fine. The slim/twig-view:3.x-dev package includes new Twig.php file.
Thanks!
