@paulomarg Could we please get this reviewed and merged at your earliest convenience?

Laravel 8 is no longer receiving bug and security fixes as of January 24th, 2023. Laravel 10 will assure everyone is using the latest and most secure version of Laravel available. This should be a high priority item.

@paulomarg @mkevinosullivan Adding my voice to the chorus here :)
Having this would be really great!
The lack of a more updated version of Laravel is actually what's pushing us to use different unofficial solutions like laravel-shopify.
Of course, using the official and maintained version from Shopify would be much better, but we can't compromise on the app security (especially since Laravel 8 is not receiving security fixes anymore)
