Merchants and shop owners using Magento Commerce 2.2.X should be aware of two critical end dates for support that affect the security and compatibility of your website.

Support for Magento Commerce 2.2.x ends on December 31, 2019
Shop operators who are still using Magento Commerce 2.2.x should update to the latest version of Magento Commerce 2.3 as soon as possible in order to take advantage of the new functions and avoid security risks.

Support for PHP 7.1 will end on November 30, 2019
PCI conformity for merchants using Magento Commerce 2.2.0-2.2.9 may be at risk from November 30, 2019 due to the end of PHP 7.1 support .

Shop operators using Magento Commerce 2.2.0-2.2.9 can solve this problem by updating to the next version of Magento Commerce 2.2 as soon as it is available in October 2019. Please note, however, that due to the planned end of support for all versions of Magento Commerce 2.2 on December 31st, it is highly recommended that you upgrade directly to the latest version of Magento Commerce 2.3.
