Adobe released Adobe Commerce and Magento Open Source 2.4.9 on May 12, 2026, adding support for PHP 8.5 and updating many platform dependencies. Three months later, on August 11, 2026, regular support ended for the 2.4.6 release line. For merchants running Magento-based stores, the two dates set the upgrade agenda for the rest of 2026: older lines are running out of support while the newest line no longer accepts older PHP versions.
What is in 2.4.9
The Adobe Commerce 2.4.9 release notes list these platform changes:
- PHP 8.5 is fully supported, PHP 8.4 is allowed for upgrade purposes only, and PHP 8.2 and 8.3 are no longer supported.
- OpenSearch 3.x compatibility, support for MariaDB 11.8 and 12.x, and Valkey 9.x as a supported alternative to Redis.
- RabbitMQ 4.2 compatibility in the short term, with Apache ActiveMQ Artemis recommended for the longer term.
- Symfony updated to the 7.4 LTS release.
- CAPTCHA and reCAPTCHA enforcement extended to REST and GraphQL APIs, and simpler two-factor authentication setup.
- The admin WYSIWYG editor moved from TinyMCE to HugeRTE, and the USPS and DHL integrations moved to REST APIs.
- New payment options through Braintree, including Apple Pay on Chrome and Firefox, plus methods such as BLIK in Poland and Pay Upon Invoice in Germany.
The support timeline
Adobe's released versions page shows these dates:
| Release line | Released | Regular support ends | Extended support ends |
|---|---|---|---|
| 2.4.6 | March 14, 2023 | August 11, 2026 | August 31, 2027 |
| 2.4.7 | April 9, 2024 | May 31, 2027 | May 31, 2028 |
| 2.4.8 | April 8, 2025 | May 31, 2028 | Not listed |
| 2.4.9 | May 12, 2026 | May 31, 2029 | Not listed |
The same page shows that extended support for 2.4.5 ended on August 11, 2026 and for 2.4.4 on April 14, 2026. In practice, merchants on older lines face a choice between three routes:
- 2.4.6 to 2.4.7: the smallest step, but regular support for 2.4.7 ends on May 31, 2027, so another upgrade follows soon.
- To 2.4.8: regular support until May 31, 2028, a middle option if some extensions are not yet ready for 2.4.9.
- To 2.4.9: the longest support window, to May 31, 2029, but it requires PHP 8.4 or 8.5 and the newest service versions.
Why it matters for merchants hiring IT firms
A store on 2.4.6 or older is now outside regular support, and the newest release requires PHP 8.4 or 8.5. For many merchants that means a combined platform and server upgrade, plus testing of extensions, themes and integrations such as payment, shipping and ERP connectors. Because every third-party extension must also support the new release, the work should start with an inventory and a compatibility check rather than a version bump.
When you request quotes from a Magento development company, ask them to list every extension and integration they will test, the target PHP, search and cache versions, and how they will handle the editor change for your content team. Ask too whether the upgrade will be done in one step to 2.4.9 or in stages, and what that means for downtime.
Why it matters for IT firms
Magento agencies should flag the 2.4.6 date to every client still on that line or older. Infrastructure changes, such as moving to OpenSearch 3.x or Valkey, may need coordination with hosting providers, and the move away from PHP 8.2 and 8.3 can affect shared servers that host several stores. Firms that offer ecommerce development can package an upgrade assessment that covers code, extensions and hosting, which makes proposals easier for clients to compare.
What to do next
- Confirm your current release line and PHP version.
- Plan a move to 2.4.8 or 2.4.9 based on extension compatibility and how long you want support to last.
- Update hosting to PHP 8.4 or 8.5 and to the supported search and cache services.
- Test checkout, payments, shipping and integrations on staging before going live.
