How to upgrade from KRadio3 to KRadio4?
When you upgrade to KRadio4, your KRadio3 kradiorc file will not be touched. The new configuration file will be called kradio4rc. However, this currently implies (additionally to some other internal changes), that the old configuration files cannot be read any more. Therefore, you have to configure KRadio4 from scratch when starting it. I’m sorry for this inconvenience, but perhaps we can see the advantage in getting a clean kradio4rc file free of legacy stuff 🙂 Please be aware, that other than the configuration file, your station preset file (which made probably much more work than the kradio configuration) can still be used by KRadio4 without any changes. It will most probably be loaded automatically if it is at the standard location (usually $KDEHOME/share/apps/kradio/stations.krp). Otherwise, please specify the proper location in the KRadio4 configuration dialog.
