Hi there,
actually to be more accurate, ForestDB will eventually replace “couchstore” (https://github.com/couchbase/couchstore), not CouchDB - just nitpicking because I know you’re into Couchbase anyways.
I don’t think we have already communicated in which version it will ship, but we are working hard on it. On the other hand, we need to make this really solid, so we probably won’t rush it. Just be on the lookout for announcements in the coming months I guess.
Cheers,
Michael
