  ([#478](https://github.com/nix-rust/nix/pull/478))
- Added support for `ioctl` calls on BSD platforms
  ([#478](https://github.com/nix-rust/nix/pull/478))
- Added struct `TimeSpec`
  ([#475](https://github.com/nix-rust/nix/pull/475))
  ([#483](https://github.com/nix-rust/nix/pull/483))
- Added complete definitions for all kqueue-related constants on all supported
  OSes
  ([#415](https://github.com/nix-rust/nix/pull/415))
- Added function `epoll_create1` and bitflags `EpollCreateFlags` in
  `::nix::sys::epoll` in order to support `::libc::epoll_create1`.
  ([#410](https://github.com/nix-rust/nix/pull/410))
- Added `setresuid` and `setresgid` for Linux in `::nix::unistd`
  ([#448](https://github.com/nix-rust/nix/pull/448))
- Added `getpgid` in `::nix::unistd`
  ([#433](https://github.com/nix-rust/nix/pull/433))
- Added `tcgetpgrp` and `tcsetpgrp` in `::nix::unistd`
  ([#451](https://github.com/nix-rust/nix/pull/451))
- Added `CLONE_NEWCGROUP` in `::nix::sched`
  ([#457](https://github.com/nix-rust/nix/pull/457))
- Added `getpgrp` in `::nix::unistd`
  ([#491](https://github.com/nix-rust/nix/pull/491))

  ([#497](https://github.com/nix-rust/nix/pull/497))
- Added `major` and `minor` in `::nix::sys::stat` for decomposing `dev_t`
  ([#508](https://github.com/nix-rust/nix/pull/508))

### Changed
- `epoll_ctl` now could accept None as argument `event`
  when op is `EpollOp::EpollCtlDel`.
  ([#480](https://github.com/nix-rust/nix/pull/480))
- Removed the `bad` keyword from the `ioctl!` macro
  ([#478](https://github.com/nix-rust/nix/pull/478))
- Changed `TimeVal` into an opaque Newtype
  ([#475](https://github.com/nix-rust/nix/pull/475))
- `kill`'s signature, defined in `::nix::sys::signal`, changed, so that the
  signal parameter has type `T: Into<Option<Signal>>`. `None` as an argument
  for that parameter will result in a 0 passed to libc's `kill`, while a
  `Some`-argument will result in the previous behavior for the contained
  `Signal`.
  ([#445](https://github.com/nix-rust/nix/pull/445))
- The minimum supported version of rustc is now 1.7.0.
  ([#444](https://github.com/nix-rust/nix/pull/444))
- Changed `KEvent` to an opaque structure that may only be modified by its
  constructor and the `ev_set` method.
  ([#415](https://github.com/nix-rust/nix/pull/415))
  ([#442](https://github.com/nix-rust/nix/pull/442))
  ([#463](https://github.com/nix-rust/nix/pull/463))
- `pipe2` now calls `libc::pipe2` where available. Previously it was emulated
  using `pipe`, which meant that setting `O_CLOEXEC` was not atomic.
  ([#427](https://github.com/nix-rust/nix/pull/427))
- Renamed `EpollEventKind` to `EpollFlags` in `::nix::sys::epoll` in order for
  it to conform with our conventions.
  ([#410](https://github.com/nix-rust/nix/pull/410))
- `EpollEvent` in `::nix::sys::epoll` is now an opaque proxy for
  `::libc::epoll_event`. The formerly public field `events` is now be read-only
  accessible with the new method `events()` of `EpollEvent`. Instances of
  `EpollEvent` can be constructed using the new method `new()` of EpollEvent.
  ([#410](https://github.com/nix-rust/nix/pull/410))
- `SigFlags` in `::nix::sys::signal` has be renamed to `SigmaskHow` and its type
  has changed from `bitflags` to `enum` in order to conform to our conventions.
  ([#460](https://github.com/nix-rust/nix/pull/460))
- `sethostname` now takes a `&str` instead of a `&[u8]` as this provides an API
  that makes more sense in normal, correct usage of the API.
- `gethostname` previously did not expose the actual length of the hostname
  written from the underlying system call at all.  This has been updated to
  return a `&CStr` within the provided buffer that is always properly
  NUL-terminated (this is not guaranteed by the call with all platforms/libc
  implementations).

### Fixed
- Fixed multiple issues with Unix domain sockets on non-Linux OSes
  ([#474](https://github.com/nix-rust/nix/pull/415))
- Fixed using kqueue with `EVFILT_USER` on FreeBSD
  ([#415](https://github.com/nix-rust/nix/pull/415))
- Fixed the build on FreeBSD, and fixed the getsockopt, sendmsg, and recvmsg
  functions on that same OS.
  ([#397](https://github.com/nix-rust/nix/pull/397))
- Fixed an off-by-one bug in `UnixAddr::new_abstract` in `::nix::sys::socket`.
  ([#429](https://github.com/nix-rust/nix/pull/429))
- Fixed clone passing a potentially unaligned stack.
  ([#490](https://github.com/nix-rust/nix/pull/490))
- Fixed mkdev not creating a `dev_t` the same way as libc.
  ([#508](https://github.com/nix-rust/nix/pull/508))

### Added
- Added `lseek` and `lseek64` in `::nix::unistd`
  ([#377](https://github.com/nix-rust/nix/pull/377))
- Added `mkdir` and `getcwd` in `::nix::unistd`
  ([#416](https://github.com/nix-rust/nix/pull/416))
- Added accessors `sigmask_mut` and `sigmask` to `UContext` in
  `::nix::ucontext`.
  ([#370](https://github.com/nix-rust/nix/pull/370))
- Added `WUNTRACED` to `WaitPidFlag` in `::nix::sys::wait` for non-_linux_
  targets.
  ([#379](https://github.com/nix-rust/nix/pull/379))
- Added new module `::nix::sys::reboot` with enumeration `RebootMode` and
  functions `reboot` and `set_cad_enabled`. Currently for _linux_ only.
  ([#386](https://github.com/nix-rust/nix/pull/386))
- `FdSet` in `::nix::sys::select` now also implements `Clone`.
  ([#405](https://github.com/nix-rust/nix/pull/405))
- Added `F_FULLFSYNC` to `FcntlArg` in `::nix::fcntl` for _apple_ targets.
  ([#407](https://github.com/nix-rust/nix/pull/407))
- Added `CpuSet::unset` in `::nix::sched`.
  ([#402](https://github.com/nix-rust/nix/pull/402))
- Added constructor method `new()` to `PollFd` in `::nix::poll`, in order to
  allow creation of objects, after removing public access to members.
  ([#399](https://github.com/nix-rust/nix/pull/399))
- Added method `revents()` to `PollFd` in `::nix::poll`, in order to provide
  read access to formerly public member `revents`.
  ([#399](https://github.com/nix-rust/nix/pull/399))
- Added `MSG_CMSG_CLOEXEC` to `MsgFlags` in `::nix::sys::socket` for _linux_ only.
  ([#422](https://github.com/nix-rust/nix/pull/422))

### Changed
- Replaced the reexported integer constants for signals by the enumeration
  `Signal` in `::nix::sys::signal`.
  ([#362](https://github.com/nix-rust/nix/pull/362))
- Renamed `EventFdFlag` to `EfdFlags` in `::nix::sys::eventfd`.
  ([#383](https://github.com/nix-rust/nix/pull/383))
- Changed the result types of `CpuSet::is_set` and `CpuSet::set` in
  `::nix::sched` to `Result<bool>` and `Result<()>`, respectively. They now
  return `EINVAL`, if an invalid argument for the `field` parameter is passed.
  ([#402](https://github.com/nix-rust/nix/pull/402))
- `MqAttr` in `::nix::mqueue` is now an opaque proxy for `::libc::mq_attr`,
  which has the same structure as the old `MqAttr`. The field `mq_flags` of
  `::libc::mq_attr` is readable using the new method `flags()` of `MqAttr`.
  `MqAttr` also no longer implements `Debug`.
  ([#392](https://github.com/nix-rust/nix/pull/392))
- The parameter `msq_prio` of `mq_receive` with type `u32` in `::nix::mqueue`
  was replaced by a parameter named `msg_prio` with type `&mut u32`, so that
  the message priority can be obtained by the caller.
  ([#392](https://github.com/nix-rust/nix/pull/392))
- The type alias `MQd` in `::nix::queue` was replaced by the type alias
  `libc::mqd_t`, both of which are aliases for the same type.
  ([#392](https://github.com/nix-rust/nix/pull/392))

### Removed
- Type alias `SigNum` from `::nix::sys::signal`.
  ([#362](https://github.com/nix-rust/nix/pull/362))
- Type alias `CpuMask` from `::nix::shed`.
  ([#402](https://github.com/nix-rust/nix/pull/402))
- Removed public fields from `PollFd` in `::nix::poll`. (See also added method
  `revents()`.
  ([#399](https://github.com/nix-rust/nix/pull/399))

### Fixed
- Fixed the build problem for NetBSD (Note, that we currently do not support
  it, so it might already be broken again).
  ([#389](https://github.com/nix-rust/nix/pull/389))
- Fixed the build on FreeBSD, and fixed the getsockopt, sendmsg, and recvmsg
  functions on that same OS.
  ([#397](https://github.com/nix-rust/nix/pull/397))
