Sprites forking functionality

I see in the April 16 release notes that sprite forking works on the admin page. When will fork be available via the REST API?

ref:

Right now, unfortunately we don’t have a timeline to share. We know this is a common request, and some work/thinking has gone into it (so we do hear you), but I don’t have anything I can share with you at this moment for when it will be exposed publicly.

So what are the release-notes for then?
Is forking functionality available for any plan?

are you saying what i think you’re saying?

The release notes are for Sprites updates generally, including API, SDK, and in this case- admin console improvements. Also, right now, there isn’t a forking functionality in general that is available.
