Key Highlights of Adobe Commerce 2.4.8
Platform Upgrades
PHP 8.3 Support
- If your Magento store is still running PHP 8.1, you'll have trouble upgrading to the most recent version.
- Magento 2.4.8 fully removes support for PHP 8.1, and that is only the beginning of the changes in this version.
- Adobe Commerce 2.4.8 now supports PHP 8.4, allowing merchants to take advantage of the latest PHP capabilities and performance enhancements.
- Notably, support for PHP 8.1 has been discontinued, necessitating an upgrade to PHP 8.3 for this release.
Database Enhancements
- MariaDB 11.4 LTS and MySQL 8.4 LTS are supported by the platform, which provides long term support and improved performance.
- While prior versions are still supported, updating to the most recent versions is recommended to ensure system integrity and speed.
- A significant database modification was the transition from UTF-8 MB3 to MB4 collation.
- Notably, support for PHP 8.1 has been discontinued, necessitating an upgrade to PHP 8.3 for this release.
ElasticSearch Drama
A major platform upgrade is a complete shift from ElasticSearch to Opensearch.
Back in 2021, ElasticSearch changed its licensing to the ELV2 license, which prohibited it from being offered as a managed service.
This threw a bit of a wrench into projects like Adobe Commerce Cloud and Amazon Web Services, and the latter forked ElasticSearch into the new offering called OpenSearch.
Library Updates
Several libraries have been updated to their latest versions, including monolog/monolog, and wikimedia/less.php, enhancing file management, logging, and CSS pre-processing capabilities.
TinyMCE Upgrade
The WYSIWYG editor has been upgraded from TinyMCE 5 to TinyMCE 7.3.0, addressing previous security vulnerabilities and providing a more stable and feature rich content editing experience.

Security Enhancements
Security is always a top priority in Magento, and this version is no different.
Encryption Key Rotation
To enhance data security, this latest version of magento introduces encryption key rotation, enabling merchants to rotate encryption keys on a regular basis, thus safeguarding sensitive data.
Subresource Integrity Support
Introducing SRI support implies that browsers can authenticate the integrity of resources fetched, securing against malicious modifications and enhancing overall site security.
Content Security Policy (CSP) Improvements
CSP enhancements enable better defence mechanisms against cross-site scripting (XSS) assaults, resulting in a more secure browsing experience for consumers.
Performance Improvements
Performance is always important for ecommerce sites, and Magento 2 latest version, includes several optimizations that can really improve your store’s loading time.
These performance improvements are huge, and they can be the difference between something like a 2% to 3% conversion rate during holiday traffic spikes.
Optimized Product Caching
Enhancements in product caching mechanisms lead to minimize the number of queries, faster page load times, improved user experience, and potentially boosted conversion rates.
Reduced Query Loads
Optimizations in upsell and cross-sell features have reduced query loads, preventing potential performance bottlenecks and ensuring smoother operations during high-traffic periods.

Developer and API Enhancements
PHPUnit 10 Compatibility
Integration and WebAPI tests are now compatible with PHPUnit 10, ensuring more accurate and efficient testing processes.
GraphQL and REST API Improvements
Enhancements in GraphQL and REST API capabilities facilitate smoother data exchanges between Adobe Commerce and third-party applications. Also if you’re building custom front ends or PWA on top of Magento, the GraphQL updates in 2.4.8 will make your life a bit easier.
The GraphQL layer now supports custom scalar types, which provides better handling in some of those complex data type scenarios, such as HTML and URLs.
Braintree Integration Updates
Updates to Braintree integrations offer expanded options for secure and flexible payment solutions.
User Interface and Content Management
TinyMCE 7.3.0 Support
Migration to TinyMCE 7.3.0 provides a more refined WYSIWYG editor for content management.
Google Maps API Update
Support for the latest Google Maps API version 3.56 ensures better integration and functionality within the platform.
Bug Fixes and Quality Improvements
Magento open source 2.4.8 addresses over 582 issues, including:
Promotion and Cart Price Rules
Fixes related to discount calculations and rule applications ensure accurate promotions and enhance marketing campaigns' reliability.
Dynamic Blocks and Widgets
Resolution of issues where widgets were not rendering properly within dynamic blocks, ensuring that content displays as intended across the platform.
Admin Area Enhancements
Improvements in the Admin interface, including proper validation of coupon codes and accurate display of product attributes, contribute to a more seamless administrative experience.
- Improved experience in:
- Checkout and cart logic
- Order management
- Product and catalog handling
