Could you please release a new version that supports mwc-random-0.11.0.0?
mwc-random is at version 0.12 by now.
I see that there have been changes in the Git repository that remedy some of the other build issues, though. Could you please release a new version of this package on Hackage? It's been over 3 months since the last official update.
We'll hopefully be releasing snap 0.8 this weekend.
