==Current Status==

DC-MHS R1 v1.0 specs have been approved by the OCP Incubation Committee in November 2022.

DC-MHS workstreams are working the MHS R1 v1.1 specifications.  Note:  M-SIF is a workstream new to DC-MHS.  An early version of the M-SIF specification (version 0.5) is included in the Latest DC-MHS Specification section.

A link to a Readme file explaining how to use the following tables (Latest DC-MHS Specifications, Errata and Supporting Documentation, and Inactive Documents) is here:  [https://docs.google.com/presentation/d/1CyVsLCPpkJb0FV_ZOYjWndqE4AHATdh-/edit?usp=share_link&ouid=107990764505043211297&rtpof=true&sd=true Link]


===Latest Released DC-MHS Specifications===

Note:  The Final Spec Agreement (FSA) for the latest specs has not yet been signed.  You may access the released versions in the Contribution Database ([https://www.opencompute.org/contributions?query=DC-MHS Contribution Database]).
