Improved logging

Although as a user you'll not see much new things, a lot is going on under the hood. This week a new logging infrastructure for scanner nodes has been rolled out. Due to the increasing number of nodes, modules and assets it had become harder to hunt down bugs. Since that is fixed, most development time for now will be spent on the newly surfacing minor bugs that went unnoticed before. Guarding quality is important, so I'm sure everyone is happy with this choice :-)
