Marble 1.2.0-1
Marble Maps 1.2.0-1

If you're using offline routing with monav-0.3 please also vote for it. It's hanging in the waiting queue for ten weeks now

@Redsandro, Estel: Setting persistentTileCacheLimit=0 in the [Cache] section in /home/user/MyDocs/.config/kde.org/Marble Desktop Globe.conf disables cache deletion. Actually that should be the default on Maemo. Does Marble delete tiles on your system? It should only refresh them after one week when visiting an area again. The refresh timeout can be configured in openstreetmap.dgml.

@Redsandro: Can you tell me which country map you downloaded and which search query/queries you tried? Searching should just work after installing a country map (from the monav config dialog). It needs a working sqlite Qt plugin, maybe that is missing on your system?

@mase: Is the sound still not working? Which speaker are you using?
