The Anaconda distribution's package/environment manager for Python (named conda) at one time used the picosat SAT solver for dependency resolution as well. I'm not certain they still do, they've removed blog entries etc. referring to it at some point.
Yes, it’s still picosat (wrapped in a python library called pycosat). At some point it may be switched out with an alternate SAT implementation, but I suspect SAT in general is very much destined to stay an integral part of conda.
