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 and PHP 7.4.x to help maintain PCI compliance.
The Support Tools are designed to identify known issues in your system. They can be used as a resource during the development and optimization processes, and as a diagnostic tool to help our support team identify and resolve issues.
