What's new June 2026

Faster, cleaner, more extensible

The June 2026 release focuses on platform performance, developer experience, and laying the groundwork for a more flexible backoffice. Key improvements to the Redis cache layer deliver better memory efficiency and observability, while API optimizations reduce unnecessary service calls for price calculations.

On the UI side, a redesigned section card component brings a cleaner, more compact look to the backoffice.

The new app UI extension framework opens up possibilities for third-party integrations using framework-agnostic web components.

Experience a cleaner backoffice with redesigned section cards

A new standard section card component replaces the existing section layout in the Litium backoffice. The redesigned cards offer a more compact and visually clear presentation, improving readability and navigation. This component establishes a consistent design pattern that will be applied across backoffice modules.

Reduce API overhead with batched price calculations

The Storefront API now resolves product prices more efficiently by addressing an N+1 query pattern in the ProductPriceResolver. Previously, the price GraphQL field was resolved independently for each ProductItemTemplate node, resulting in multiple service calls. This optimization reduces redundant calls to the PriceCalculator, improving response times for product listings and catalog queries.

Boost Redis cache performance with compression and better observability

The distributed cache layer receives several improvements targeting performance, reliability, and monitoring. GZip compression reduces memory usage by compressing cache values before storage in Redis. Additional enhancements address memory pressure handling and cache invalidation logic. New observability features provide better insight into cache behavior and performance metrics.

Extend the backoffice UI with framework-agnostic web components

The app UI extension framework introduces support for Web Component (Custom Element) extensions as a new target type. This approach is framework-agnostic, meaning extensions do not need to be compiled against a specific frontend framework. Developers can now build custom backoffice UI extensions using standard web technologies, enabling more flexible third-party integrations.
