- In API version 2027-01, the Navigation API currententrychange event's event.from now contains the previous page instead of the new page for customer account full‑page extensions.
- Update any currententrychange handlers to read the new page from shopify.navigation.currentEntry (or the useNavigationCurrentEntry hook) rather than event.from.
- Make this change before upgrading extensions to API version 2027-01 to avoid broken navigation behavior.
