Adobe Commerce officially deprecated Magento 1 for all Commerce and Open Source versions of Magento 1 on June 30, 2020. In addition to the platform deprecation, the Magento Marketplace will no longer accept or host Magento 1 plugins by July 7, 2020 and Klarna checkout and Klarna Payments m1 plugins will be removed.

Magento 1 solutions are available via Github (Klarna payments, Klarna checkout) for merchant use at their own risk. Klarna will no longer provide updates to the plugins nor support services for the plugins.
