+    when running an network with ircd2 servers and "OperCanUseMode" enabled
+    to prevent the ircd2 daemon to drop mode changes of IRC operators.
+    Patch by Florian Westphal, <westphal@foo.fh-furtwangen.de>.
   - Implemented support for "secret channels" (channel mode "s").
   - New configuration option "Mask" for [Operator] sections to limit OPER
