Industry feedback is fundamental to the evolution of the PCI Data Security Standard (PCI DSS). Because of the broad impact PCI DSS has on the payment community, the Council is seeking additional feedback into the PCI DSS v4.0 validation documents. As a result of expanding stakeholder feedback opportunities to include these supporting documents, the Council is now targeting a Q4 2021 completion date for PCI DSS v4.0. The publication and availability of PCI DSS v4.0 is still being determined. The Council will communicate the targeted publication date in the coming months.
