Hi Michal,
I don't think there are plans to port CAFE on bioconda, but you can ask Ben directly. He'd be the person to tell you what's what in terms of software release.
CAFE 5 should be able to take input in the same format as previous versions of CAFE, unless things have changed. But the output files will be different, and you don't have to run any auxiliary scripts.
From your activity and type of questions you post in this Google group, I predict sooner or later you will be tempted to ask us about CAFE 5. Before you do that, I urge you to read the documentation and tutorial for CAFE 5, check its paper, and put an effort into understanding how CAFE 5 differs from its predecessors.
I hope this helps.
cheers,
Fábio
