>It looks to me as if the process of updating the maps from OSM for Kartographer has stopped.
That is correct. We’re sorry not to have alerted this list. We paused the pulling of updates from OSM while generating a whole new set of map tiles ahead of the internationalization release[1].
The process will restart soon and should take a few days to catch up. Our engineers estimate that everything should be up to date again by Monday, the 30th. Sorry for any inconvenience!
