 ngIRCd HEAD
 
+  - Predefined Channel configuration now allows specification of channel key
+    (mode k) and maximum user count (mode l).
   - When using epoll() IO interface, compile in the select() interface as
     well and fall back to it when epoll() isn't available on runtime.
   - New configure option "--without-select" to disable select() IO API
