After July 2021, the 2.3.x release line will no longer receive quality updates, or user guide updates. PHP 7.3 reaches end of support in December 2021 and Adobe Commerce 2.3.x reaches end of support in September 2022. We strongly recommend planning your upgrade now to Adobe Commerce 2.4.x to help maintain PCI compliance.


The information on this page is intended for Adobe Commerce 2.3 customers who are on an extended support contract. The Adobe Commerce Merchant Documentation for current releases is published on the Adobe Experience League.
