Manifold 0.2.3 is now out, featuring the new go-off macro, which is based off core.async/go. Also includes a bugfix adding bound-fn for let-flow. Many, many thanks to Ryan Smith (@tanzoniteblack) for adding go-off to Manifold, and to the rest of Yummly for offering it back upstream. https://github.com/clj-commons/manifold/blob/master/CHANGES.md
