Hi,
you changes a lot of highway=path, highway=construction and even razed:highway into cycleways/footways. Parts of the path you changed are razed and completely new build (which is not applied on outdated street imagery)  cycleways have a traffic sign DE:237 and footways have a traffic sign DE:239 see https://wiki.openstreetmap.org/wiki/DE:Bicycle/Radverkehrsanlagen_kartieren. This is not the case here. These are combined ways for foot/bicycle. So I have to fix that again. BR
