Major Platform Upgrade: .NET 10

Upgrading to .NET 10 underpins many of the performance improvements in this release. Users can expect faster load times, better scalability, and improved overall responsiveness. This upgrade also future-proofs the platform, ensuring compatibility with the latest Microsoft ecosystem advancements.

New Commercial Plugins: Withdrawal and Warranty

Two new commercial plugins address critical compliance and customer service needs:

Withdrawal Plugin: Enables customers to submit withdrawal requests online for eligible orders and items, supporting compliance with EU digital withdrawal regulations. This streamlines the returns process and improves transparency.
Warranty Plugin: Allows store owners to configure and display harmonized EU labels for legal guarantees and commercial guarantees of durability. This feature helps businesses meet legal obligations and communicate warranty information clearly to customers.

Enhanced AI Features

Smartstore continues to integrate AI to improve content management and customer engagement:

Automatic llms.txt Generation: Automates the creation of this file, aiding AI model management.

Improved User Experience and Storefront Features

Required Products: Automatically added required products can no longer be removed independently, and their quantities can sync with the main product. There’s also a new setting to display prices of these products below the main product price.
Wallet Improvements: Wallet credits can be added anywhere via a PageBuilder block, and credit amounts can be displayed as buttons when purchasing credit.
Google Merchant Center (GMC) Enhancements: New settings allow exporting only products with Google data, and product permissions are better respected.
