source: https://developer.mastercard.com/payment-account-management/documentation/release-history/index.md

This page contains pre-release Notes for the Payment Account Management (PAM) Application Programming Interface (API), providing early warning of intended changes and additions to the APIs. Only once the API update has been released to Mastercard Test Facility (MTF) will the specification be updated in the API Reference section. Therefore, the pre-release notes are the only place where upcoming changes are documented in advance of each release. Each document provides up-to-date details of the changes expected, and should be considered accurate at the point of publication.
