New maps are out.

This time, I am retiring libosmscout map datasets. There was an error during import and, as I use very old version of that lib, I decided not to fight it, but drop that dataset. As nobody volunteered to support libosmscout backend (I think I notified regarding dropping support for it years ago), libosmscout backend will be also disabled in the upcoming official builds. Code is still there, just commented out via MACROs.
