I am mainly thinking of testing, and if FiveAM is still the way to go, because there is a note at the beginning about Rove, which seems to be pretty well maintained these days. But looking at FiveAM again I see some recent commits. Also, in the concurrency chapter there is the section on lparallel, which seems like a very old unmaintained library.
This all said, I think one thing that makes cl nice is that it doesn't feel out of the question to use a very old library for something you need. So none of this is actually a problem.
FiveAM is still a very good solution, difficult to replace. We didn't replace it with another test framework, and we looked at a few of them. Rove doesn't live on its promise to run `rove <system>` on the command line for example.
