+  ngIRCd 0.10.2-pre2 (2007-05-19)

+
+  ngIRCd 0.10.2-pre1 (2007-05-05)
+  - Fix compressed server links (broken since 0.10.0).
+  - 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.
