Adobe Commerce 2.4.9-alpha2: OpenSearch 3.x Compatibility

On August 12, 2025, Adobe released Adobe Commerce 2.4.9-alpha2, continuing the evolution toward modernised technical foundations. This release focuses on infrastructure compatibility, supporting OpenSearch 3.x, Nginx 1.28, and Composer 2.4+, enabling merchants to run on the latest generation of supporting technologies.

OpenSearch 3.x Support

OpenSearch, the open-source search engine powering Adobe Commerce, released version 3.x with significant performance improvements. OpenSearch 3.x delivers 30% faster search operations, improved memory efficiency, and enhanced security capabilities. For merchants managing large catalogues with thousands of products, these performance gains are substantial. Commerce 2.4.9-alpha2 enables merchants to upgrade to OpenSearch 3.x and realise these performance benefits.

Nginx 1.28 Compatibility

Nginx 1.28 brings improved concurrency handling, better load balancing algorithms, and enhanced HTTP/2 support. For merchants managing high-traffic storefronts, Nginx 1.28 improves request handling efficiency and reduces server resource requirements. Commerce 2.4.9-alpha2 compatibility ensures merchants can upgrade web servers without platform compatibility issues.

Composer 2.4+ Support

Composer, the PHP dependency manager, continues evolving. Version 2.4+ introduces faster dependency resolution, improved security scanning, and better handling of complex extension ecosystems. For development teams, Composer 2.4+ support means faster deployment pipelines and more reliable dependency management.

Alpha Testing and Feedback

As an alpha release, 2.4.9-alpha2 is intended for testing and feedback rather than production deployment. Merchants interested in modernising infrastructure should begin testing in development environments. Feedback on compatibility issues, performance, and feature functionality informs the final 2.4.9 release.

Upgrade Path

Merchants currently on 2.4.8 can expect a straightforward upgrade path to 2.4.9. The focus on infrastructure compatibility rather than breaking API changes means existing extensions should continue working with minimal modification. Most merchants can plan 2.4.9 upgrades as routine maintenance rather than major projects.

Strategic Value

By maintaining compatibility with modern infrastructure components, Adobe ensures Commerce remains on a current technology foundation. For merchants planning infrastructure modernisation, 2.4.9 compatibility removes obstacles. For Tom&Co's development partnerships, the modern infrastructure support enables us to recommend contemporary solutions without worrying about platform compatibility.
