Class Paazl\CheckoutWidget\Plugin\Multishipping\Block\Checkout\Address located in ./vendor/paazl/magento2-checkout-widget/Block/Checkout/Address.php does not comply with psr-4 autoloading standard. Skipping.

I get an error on this class and I understand why.

The namespace is:
namespace Paazl\CheckoutWidget\Plugin\Multishipping\Block\Checkout;

While the file path is:
Block/Checkout/Address.php

"Plugin/Multishipping" should be removed from the namespace and from the frontend/di.xml aswell.

Thanks for fixing this, maybe close the ticket yourself next time. And a mention in the Release Notes would be nice :)
