## [Unreleased]
### Added
+- Added `::nix::sys::termios::BaudRate` enum to provide portable baudrate
+ values. ([#518](https://github.com/nix-rust/nix/pull/518))
- Added a new `WaitStatus::PtraceEvent` to support ptrace events on Linux
and Android ([([#438](https://github.com/nix-rust/nix/pull/438))
- Added support for POSIX AIO

### Changed
+- `::nix::sys::termios::{cfgetispeed, cfsetispeed, cfgetospeed, cfsetospeed}`
+ switched to use `BaudRate` enum from `speed_t`.
+ ([#518](https://github.com/nix-rust/nix/pull/518))
- `epoll_ctl` now could accept None as argument `event`
when op is `EpollOp::EpollCtlDel`.
