We read a news from PayPal to update the paypal integration antil January 18, 2017.
(https://www.paypal-knowledge.com/infocenter/index?page=content&id=FAQ2067&expand=true&locale=en_US)
As I read in related post (https://community.magento.com/t5/Programming-Questions/Any-action-required-Update-PayPal-Integration...) - PayPal can't say, if any action required for Magento's PayPal integration.
Do anybode have any other information about this issue?
