+\subsubsection*{Obsolete procedures}
+
+Names in further versions of \ex{pop3} contained a colon (`\ex{:}')
+after the prefix `\ex{pop3-}'. This is now changed to a hyphen
+('\ex{-}'), accordingly to SUnet's philosophy. If you need the old
+names, use the \ex{pop3\=obsolete}-package that maps the old names to
+the new ones.
