HPDC has updated the HPD Open Standard several times, from version 1 in 2012 to today.
HPDC roughly aims to release updates to the HPD Open Standard on an annual cycle. Within an update cycle, revisions are considered throughout the year as HPDC Technical Committee and Technical Sub-Groups, with the help of HPDC staff, can prioritize their discussion.
Suggestions for improvement are welcome at any time, from anyone. HPDC members may be explicitly asked, via email notification, for suggestions. Members and non-members alike are invited to contact HPDC anytime with questions or suggestions.
In the event that an issue is found that needs more immediate improvement in order to ensure the effective functioning of the Standard, the HPD Open Standard revision process allows for the issuance of errata and addenda in the interim period between full version releases.
