CMS recently released the initial draft version of the MDS v1.18.0 that was to become effective in October, 2020. The changes have been postponed for now due to the corona virus.
The biggest change in the draft is the elimination of Section G. Section GG is retained.
CMS has also published tables detailing the changes to each section of the MDS assessment form. The files for the initial draft and the change tables can be accessed on the CMS page:
