|
||||
|
||||
- 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.
