I've been using Daemontools v3.47 for years now and it's been great. I understand that the subsequent versions were adware based and because of that I've never bothered to use 4.x.
Is there any perceivable reason to use the newer versions of Daemontools? If there is and the adware isn't too difficult to remove I'd like to know. If there's no real gains I'll still use the good ol' 3.47.
