+need to configure this manually anymore.
+
+*** The LDAP configuration section of EUDC's manual has been
+rewritten.
+
+There have also been customization changes.
+
+*** New custom variable `eudc-server-hotlist' to allow specifying
+multiple EUDC servers in init file.
+
+*** Custom variable `eudc-inline-query-format' defaults to completing
+on email and firstname instead of surname.
+
+*** Custom variable `eudc-expansion-overwrites-query' defaults to nil
+to avoid interfering with the kill ring.
+
+*** Custom variable `eudc-inline-expansion-format' defaults to
