All JavaScript libraries and NPM dependencies have also been updated.

GraphQL and API Advancements

GraphQL capabilities have been significantly enhanced in Magento 2.4.7. The release offers improved GraphQL caching abilities and schema support for custom attributes, speeding up page load times. New GraphQL resolver cache types for CMS pages and blocks are introduced, alongside improved GraphQL parser performance. For Adobe Commerce users, a new PHP application server based on the Swoole PHP extension allows for state persistence across GraphQL API calls, reducing API response times by an estimated 50-60 milliseconds. Furthermore, new REST endpoints for managing multiple coupons in a cart have been added, and the `clearCart` mutation replaces the deprecated `clearCustomerCart` mutation. The `createGuestCart` mutation is introduced to replace the deprecated `createEmptyCart` mutation.

Performance Optimizations

Performance improvements are evident across various aspects of Magento 2.4.7. Load times for product listing pages with complex products (over 100 options) have improved. GraphQL requests for listing products by category have also seen performance gains. For enterprise deployments with a large number of active sales rules (around 100,000), performance degradation during checkout operations is mitigated. Adobe Commerce 2.4.7 also boasts improved performance for large product catalogs and complex promotions, alongside faster save operations for store-level configurations in deployments with over 500 stores.

Deprecations and Migrations

Notable deprecations include `clearCustomerCart` and `createEmptyCart` mutations in GraphQL, replaced by `clearCart` and `createGuestCart`, respectively. For developers migrating from older versions or platforms, understanding these changes is crucial. The migration from legacy FedEx WSDL Web Services to FedEx RESTful APIs is complete, and the Commerce UPS XML API gateway has been migrated to the new Commerce UPS REST API. Support for new shipping methods like USPS Ground Advantage has been added.

Practical Implications: What This Means for R&D Engineers

The technical updates in Magento 2.4.7 translate into several practical considerations for R&D engineers:
