- `AioCb::Drop` will now panic if the `AioCb` is still in-progress ([#715](https://github.com/nix-rust/nix/pull/715))
- Restricted `nix::sys::socket::UnixAddr::new_abstract` to Linux and Android only.
([#785](https://github.com/nix-rust/nix/pull/785))

- Removed return type from `pause`.
([#829](https://github.com/nix-rust/nix/pull/829))
- Changed the termios APIs to allow for using a `u32` instead of the `BaudRate`
enum on BSD platforms to support arbitrary baud rates. See the module docs for
`nix::sys::termios` for more details.
([#843](https://github.com/nix-rust/nix/pull/843))
### Fixed
- Fix compilation and tests for OpenBSD targets
([#688](https://github.com/nix-rust/nix/pull/688))
- Fixed error handling in `AioCb::fsync`, `AioCb::read`, and `AioCb::write`.
It is no longer an error to drop an `AioCb` that failed to enqueue in the OS.
([#715](https://github.com/nix-rust/nix/pull/715))
- Fix potential memory corruption on non-Linux platforms when using
`sendmsg`/`recvmsg`, caused by mismatched `msghdr` definition.
([#648](https://github.com/nix-rust/nix/pull/648))
### Removed
- `AioCb::from_boxed_slice` has been removed. It was never actually safe. Use
`from_bytes` or `from_bytes_mut` instead.
([#820](https://github.com/nix-rust/nix/pull/820))
- The syscall module has been removed. This only exposed enough functionality for
`memfd_create()` and `pivot_root()`, which are still exposed as separate functions.
([#747](https://github.com/nix-rust/nix/pull/747))
- The `Errno` variants are no longer reexported from the `errno` module. `Errno` itself is no longer reexported from the
crate root and instead must be accessed using the `errno` module. ([#696](https://github.com/nix-rust/nix/pull/696))
- Removed `MS_VERBOSE`, `MS_NOSEC`, and `MS_BORN` from `MsFlags`. These
are internal kernel flags and should never have been exposed.

events from `wait` and `waitpid` using `WaitStatus::PtraceSyscall`
([#566](https://github.com/nix-rust/nix/pull/566)).
### Changed
- The `ioctl!` macro and its variants now allow the generated functions to have
doccomments. ([#661](https://github.com/nix-rust/nix/pull/661))
- 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))

- 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))

([#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))

`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

- `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))

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))

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))

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))

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))

`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.
