For those following along hoping for an up to date beta 5 of this release, sorry for the very long silence! There was an internal push to get CHT 4.0.0 released and this feature ended up getting pushed out to be after 4.0.0.
We’re very much still working on this feature and have 112 commits, 110 files updated and over 200 comments on the PR. It is currently slated to be released in 4.1.0!
