Concurrent-0.2.2 released (bugfixes)

has been released; it removes some leftover code from an earlier version
that prevented lazy evaluation from working, as well as fixing a C++ism
in futures.c which was causing grief for Windows users (thanks to Tim
Fletcher for bringing this to my attention).

As always, downloadables are here:
