Braintree payment integration: Prior to Magento 2.4.0, it was recommended that merchants install and configure the official Braintree payment integration extension from the Commerce Marketplace to replace the core integration. With this release (Magento 2.4.0), the extension is now included in the Magento release. Because of this you should remove any 3rd party Modules prior to the the upgrade. Merchants must follow additional steps to ensure that Braintree works properly in a Magento 2.4.0 deployment. See Braintree for more information on how to migrate to Magento 2.4.0.
