I don’t believe this page has been updated to note that it won’t be released in F27 as hoped due to systemic problems in the beta: https://communityblog.fedoraproject.org/modularity-dead-long...

I’m looking forward to seeing what they’re going to do with it next; this is a super tough problem to get right in a supportable way. I have a lot of faith in the Fedora team to put together something awesome.
