+- Channels that are no longer contained in the current SDT of a transponder are now
+  marked with the keyword OBSOLETE in their name and provider fields. That way you can
+  identify obsolete channels when you switch to them, and you can get the complete
+  overview of all obsolete channels by sorting the Channels list by provider (by
+  pressing the 0 key twice). Automatic deletion of obsolete channels may follow later.
