Key Features in Adobe Commerce 2.4.9
1. PHP 8.5 Compatibility
One of the biggest highlights of Adobe Commerce 2.4.9 is full compatibility with PHP 8.5. Adobe Commerce now officially supports:
- PHP 8.3
- PHP 8.4
- PHP 8.5
At the same time, PHP 8.2 support has been removed. This helps merchants prepare for future PHP end-of-life deadlines while improving performance and security. (Experience League)
2. Valkey 8.x Support
Adobe Commerce 2.4.9 adds complete support for Valkey 8.x as a Redis-compatible caching backend.
This change is important because Redis licensing and support concerns have pushed many enterprise platforms toward Valkey as a long-term alternative. Adobe now supports Valkey across multiple Commerce release lines. (Experience League)
Benefits of Valkey Support
- Better long-term infrastructure flexibility
- Redis-compatible functionality
- Improved cache reliability
- Simplified migration path
3. ActiveMQ Artemis Support
Adobe Commerce 2.4.9 introduces support for Apache ActiveMQ Artemis as an alternative to RabbitMQ.
This update gives enterprise merchants more flexibility for queue management and cloud-native deployments. (Experience League)
4. Symfony Cache Replaces Zend_Cache
Adobe has officially replaced the deprecated Zend_Cache framework with Symfony Cache.
This modernization improves:
- Cache performance
- PHP 8.x compatibility
- Maintainability
- Long-term framework stability
Existing cache backends continue working without major migration changes. (Experience League)
5. Symfony 7.4 LTS Support
Adobe Commerce 2.4.9 upgrades all Symfony dependencies to Symfony 7.4 LTS.
This provides:
- Better long-term support
- Improved framework security
- Modern PHP compatibility
- Updated dependency management
Developers extending Symfony core classes may need to update method signatures and type declarations. (Experience League)
6. Composer 2.9 Compatibility
The platform now fully supports Composer 2.9, helping developers maintain modern dependency management workflows and deployment pipelines. (Experience League)
