Yes, data are irregularly updated. Usually once per month. See

Well, some users in past mapped addresses on outlines. We did not retag
them. Import script is able to handle such situation.

Regarding rest of your email below, I don't think that, right now, we
need any address complementation in Czech Republic. But we are using
almost the same system as Slovakia and they are still collecting addresses.

Thanks for StreetComplete and best regards,
Marián
