I just released reactive-0.10.4 and reactive-glut-0.1.5. Highlights: * Improving values: QuickCheck tests, before and after functions, non-default max method. * makeEvent now yields (sink,event) instead of (event,sink). This new order is Functor-friendlier. And perhaps Arrow-friendly as well. If you've written an adapter, you'll probably have to tweak it, as I did for reactive-glut-0.1.5. * Added Reactive.Internal.Chan, which is a copy of Control.Concurrent.Chan, but with a new function weakChanWriter. The point for data consumers to keep data producers alive. I'll pitch weakChanWriter for inclusion in Control.Concurrent.Chan. * Internal.TVal: plug space leak for external inputs (I think), using weakChanWriter. Added getChanStream, which is like getChanContents, but makes a stream. * Added dependency on the Stream package. * PrimReactive: futureStreamE, using a refutable pattern, which may help laziness. Added some snapshot variants, commented out. - Conal
