Already for a a few days my XFCE weather plugin (xfce-extra/xfce4-weather-plugin-0.8.3-r1) does not work (forecast data unavailable).
Its website (http://goodies.xfce.org/projects/panel-plugins/xfce4-weather-plugin) says that "You need to apply two patches on version 0.8.3 because Met.no API has changed." May be it is the cause. If so, may I ask supporters to make the corresponding changes to the ebuild.
