Version 0.4 of Streaming Component Combinators, or SCC for short, has been released on Hackage. Get it at

There isn't much new high-level functionality compared to the previous version, but the implementation has been heavily refactored and the foundations completely replaced.
Stupid question: Is it related to Arrows?
Not really. You might say it's more general than arrows, because the streaming components are not restricted to a single input and single output type. On the other hand, they are all specific to stream processing, much like Fudgets and Yampa which are arrow-based. I suppose the Transducer data type [1] could be made an Arrow instance, which would let me rename the 'connect' combinator [2] to (>>>). I'll have a look at Yampa to see if I can harvest more combinator names, thank you! [1] http://hackage.haskell.org/packages/archive/scc/0.4/doc/html/Control-Concurr...
