  ([#456](https://github.com/nix-rust/nix/pull/456))
- Added `nix::ptrace::{ptrace_get_data, ptrace_getsiginfo, ptrace_setsiginfo
  and nix::Error::UnsupportedOperation}`
  ([#614](https://github.com/nix-rust/nix/pull/614))
- Added `cfmakeraw`, `cfsetspeed`, and `tcgetsid`. ([#527](https://github.com/nix-rust/nix/pull/527))
- Added "bad none", "bad write_ptr", "bad write_int", and "bad readwrite" variants to the `ioctl!`
  macro. ([#670](https://github.com/nix-rust/nix/pull/670))
- On Linux and Android, added support for receiving `PTRACE_O_TRACESYSGOOD`
  events from `wait` and `waitpid` using `WaitStatus::PtraceSyscall`
  ([#566](https://github.com/nix-rust/nix/pull/566)).

### Changed
- Changed `ioctl!(write ...)` into `ioctl!(write_ptr ...)` and `ioctl!(write_int ..)` variants
  to more clearly separate those use cases. ([#670](https://github.com/nix-rust/nix/pull/670))
- Marked `sys::mman::{ mmap, munmap, madvise, munlock, msync }` as unsafe.
  ([#559](https://github.com/nix-rust/nix/pull/559))
- Minimum supported Rust version is now 1.13.
- Removed `revents` argument from `PollFd::new()` as it's an output argument and
  will be overwritten regardless of value.
  ([#542](https://github.com/nix-rust/nix/pull/542))
- Changed type signature of `sys::select::FdSet::contains` to make `self`
  immutable ([#564](https://github.com/nix-rust/nix/pull/564))
- Introduced wrapper types for `gid_t`, `pid_t`, and `uid_t` as `Gid`, `Pid`, and `Uid`
  respectively. Various functions have been changed to use these new types as
  arguments. ([#629](https://github.com/nix-rust/nix/pull/629))
- Fixed compilation on all Android and iOS targets ([#527](https://github.com/nix-rust/nix/pull/527))
  and promoted them to Tier 2 support.
- `nix::sys::statfs::{statfs,fstatfs}` uses statfs definition from `libc::statfs` instead of own linux specific type `nix::sys::Statfs`.
  Also file system type constants like `nix::sys::statfs::ADFS_SUPER_MAGIC` were removed in favor of the libc equivalent.
  ([#561](https://github.com/nix-rust/nix/pull/561))
- Revised the termios API including additional tests and documentation and exposed it on iOS. ([#527](https://github.com/nix-rust/nix/pull/527))
- `eventfd`, `signalfd`, and `pwritev`/`preadv` functionality is now included by default for all
  supported platforms. ([#681](https://github.com/nix-rust/nix/pull/561))
- The `ioctl!` macro's plain variants has been replaced with "bad read" to be consistent with
  other variants. The generated functions also have more strict types for their arguments. The
  "*_buf" variants also now calculate total array size and take slice references for improved type
  safety. The documentation has also been dramatically improved.
  ([#670](https://github.com/nix-rust/nix/pull/670))

### Removed
- Removed `io::Error` from `nix::Error` and the conversion from `nix::Error` to `Errno`
  ([#614](https://github.com/nix-rust/nix/pull/614))
- All feature flags have been removed in favor of conditional compilation on supported platforms.
  `execvpe` is no longer supported, but this was already broken and will be added back in the next
  release. ([#681](https://github.com/nix-rust/nix/pull/561))
- Removed `ioc_*` functions and many helper constants and macros within the `ioctl` module. These
  should always have been private and only the `ioctl!` should be used in public code.
  ([#670](https://github.com/nix-rust/nix/pull/670))

### Fixed
- Fixed multiple issues compiling under different archetectures and OSes.
  Now compiles on Linux/MIPS ([#538](https://github.com/nix-rust/nix/pull/538)),
  `Linux/PPC` ([#553](https://github.com/nix-rust/nix/pull/553)),
  `MacOS/x86_64,i686` ([#553](https://github.com/nix-rust/nix/pull/553)),
  `NetBSD/x64_64` ([#538](https://github.com/nix-rust/nix/pull/538)),
  `FreeBSD/x86_64,i686` ([#536](https://github.com/nix-rust/nix/pull/536)), and
  `Android` ([#631](https://github.com/nix-rust/nix/pull/631)).
- `bind` and `errno_location` now work correctly on `Android`
  ([#631](https://github.com/nix-rust/nix/pull/631))
- Added `nix::ptrace` on all Linux-kernel-based platforms
  [#624](https://github.com/nix-rust/nix/pull/624). Previously it was
  only available on x86, x86-64, and ARM, and also not on Android.
- Fixed `sys::socket::sendmsg` with zero entry `cmsgs` parameter.
  ([#623](https://github.com/nix-rust/nix/pull/623))
- Multiple constants related to the termios API have now been properly defined for
  all supported platforms. ([#527](https://github.com/nix-rust/nix/pull/527))
- `ioctl!` macro now supports working with non-int datatypes and properly supports all platforms.
  ([#670](https://github.com/nix-rust/nix/pull/670))

## [0.8.1] 2017-04-16

- 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`

- Added `fchdir` in `::nix::unistd`
  ([#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))
- Fixed the style of many bitflags and use `libc` in more places.
  ([#503](https://github.com/nix-rust/nix/pull/503))
- Added `ppoll` in `::nix::poll`
  ([#520](https://github.com/nix-rust/nix/pull/520))
- Added support for getting and setting pipe size with fcntl(2) on Linux
  ([#540](https://github.com/nix-rust/nix/pull/540))

### 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`.
  ([#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).
- Exposed all fcntl(2) operations at the module level, so they can be
  imported direclty instead of via `FcntlArg` enum.
  ([#541](https://github.com/nix-rust/nix/pull/541))

### 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 `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))

  ([#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))

- `sockaddr_storage_to_addr` in `::nix::sys::socket` now supports `sockaddr_nl`
  on _linux_ and _android_.
  ([#366](https://github.com/nix-rust/nix/pull/366))
- Added support for `SO_ORIGINAL_DST` in `::nix::sys::socket` on _linux_.
  ([#367](https://github.com/nix-rust/nix/pull/367))
- Added `SIGINFO` in `::nix::sys::signal` for the _macos_ target as well as
  `SIGPWR` and `SIGSTKFLT` in `::nix::sys::signal` for non-_macos_ targets.
  ([#361](https://github.com/nix-rust/nix/pull/361))

  `Result<()>` in `::nix::unistd`.
  ([#357](https://github.com/nix-rust/nix/pull/357))

### Fixed
- Improved the conversion from `std::net::SocketAddr` to `InetAddr` in
  `::nix::sys::socket::addr`.
  ([#335](https://github.com/nix-rust/nix/pull/335))

## [0.5.0] 2016-03-01
