ngIRCd 0.10.2
+
+ - 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
+ (even when using epoll(), see above).
+ - Added support for IO APIs "poll()" and "/dev/poll".
- Reorganized internal handling of invite and ban lists.
