I've updated the underlying GWR data for https://qa.poole.ch/addresses/ch/ and https://qa.poole.ch/ch-roads/ to the current data as of yesterday (2024-10-29) the previous data was from April 2024.

Since the GWR switched to including all buildings and not just those with a postal address a couple of years ago I've filtered out addresses of the form NN.N from the overall statistics (they are available in the files that contain "all" entries) as these are not "real" addresses, I've further refined that now by ignoring buildings with the category values 1010 and 1080 see https://www.housing-stat.ch/de/help/42.html

The changes and the update has reduced the overall count of relevant addresses in the GWR from 2'407'343 to 2'367'012 and the number of  these missing in OSM from 732'394 to 698'960, the largest change probably being in Zürich which lost ~4'000 (Zürich is one of the municipalities that historically assigned any kind of building a regular house number, including for example the platform roofs at Altstetten station). The overall number of buildings (not addresses) in the GWR went up from 3'239'916 to 3'264'326 over the half year period since April.
