The CSS WG has published an updated Working Draft of the CSS Ruby Layout 
Module Level 1:

     https://www.w3.org/TR/css-ruby-1/

“Ruby”, a form of interlinear annotation, are short runs of text alongside the 
base text. They are typically used in East Asian documents to indicate 
pronunciation or to provide a short annotation. This module describes the 
rendering model and formatting controls related to displaying ruby annotations 
in CSS.

Major changes include:
   * Adding an 'alternate' keyword as the initial value of 'ruby-position'
   * Renaming 'ruby-merge: collapse' to 'ruby-merge: merge'
   * Defining 'visibility: collapse' to hide annotations explicitly
   * Redrafting most of the Ruby Layout section to more precisely define
     interlinear and inter-character layout and its interaction with ruby-align
       https://drafts.csswg.org/css-ruby-1/#ruby-layout
   * Additional figures and examples throughout

The full list of changes since the April 2020 draft is available at:
   https://drafts.csswg.org/css-ruby-1/#changes

There are still a number of known issues open, most of which are about pinning 
down details in the layout rules. Issues are currently tracked in two places:
   http://drafts.csswg.org/css-ruby-1/issues-wd-2020
 
https://github.com/w3c/csswg-drafts/issues?q=is%3Aopen+is%3Aissue+label%3Acss-ruby-1

Please review the draft, and send any comments to this mailing list,
<www-style@w3.org>, prefixed with [css-ruby] (as I did on this
message) or (preferably) file them in the GitHub repository at
   https://github.com/w3c/csswg-drafts/issues

For the CSS WG,
