The current version of the HPD Open Standard is Version 2.1.1.  "Current Version" denotes the version of the Standard that is in use for newly-publishing HPD reports.  The current version is fully implemented in the HPD Builder, HPD Public Repository and APIs used for automated data transfer to other systems.

On May 7, 2019, HPD Open Standard Version 2.2 was released. "Released" means that the updates to the Standard have been fully approved by the HPDC Technical Committee and Board of Directors.  Documentation of the Standard is available on the HPDC website for download.  Full implementation of HPD v2.2 is planned for Q3 2019, at which point v2.2 will become the "current version."
