filp/Whoops package still show old UI after upgrading to Laravel 5.5

With the release of Laravel 5.5 last week, the package filp/Whoops got revamped.

However, if you follow the official Laravel 5.5 upgrade guide, it does not mention anything about filp/Whoops.

As a result, you will still have the old filp/Whoops UI. So how do you get the new filp/Whoops version with Laravel 5.5?
