Thankyou for above reply,
Currently, I'm using same Bitnami Shopware Stack versions 5.5.3 provided by you on my local (Windows OS) and host environment (LINUX OS).
I need to update PHP for currently installed Btnami Shopware Stack that's why I asked for Bitnami Shopware Stack version 5.6.
I have to update PHP from 7.0.23 to 7.2.
So, please provide Installer link for Bitnami Shopware Stack version 5.6 for LINUX and Windows.
Or let me know if there is any other way to update the PHP version within same Bitnami Shopware Stack 5.5.3 for both Linux and Windows.
