Checkout loads faster: checkout data can start loading as soon as the checkout form appears (prefetch).
Shipping and payment options display more reliably when the delivery address or country changes (correct selected carrier, extra content shown for the right option).
Virtual carts hide the shipping block so the payment section uses the full width.
After social login, redirect handling is safer and more predictable (invalid or unsafe “back” links are ignored; login loops to the authentication page are avoided).
Colissimo pickup point: address from the checkout form is synced when opening/editing a pickup point (avoids empty or placeholder “opc” address data).
Stripe Official payment form is more stable on the one-page checkout (fewer broken/missing payment fields after refresh).
Address updates only refresh shipping when relevant fields change (country, state, postcode), reducing unnecessary reloads.
Better compatibility with PHP 8.2+ for social login (OAuth).
