ArchLinux is a rolling release distro depending on the most recent upstream packages (usually installed `as is' with no modifications). XFCE 4.14, especially: xfce4-panel 4.14.0-1 After 4.12->4.14 upgrade I can use the old Notification Area but it behaves as an obsolete not supported applet. Moreover: Panel -> Add New Items displays this applet greyed; I can't add a new one.
