- Enabled `sys::ptrace::setregs` and `sys::ptrace::getregs` on x86_64-unknown-linux-musl target
(#[1198](https://github.com/nix-rust/nix/pull/1198))
- On Linux, `ptrace::write` is now an `unsafe` function. Caveat programmer.
(#[1245](https://github.com/nix-rust/nix/pull/1245))
- `execv`, `execve`, `execvp` and `execveat` in `::nix::unistd` and `reboot` in

- `sys::socket::sockaddr_storage_to_addr` is no longer `unsafe`. So is
`offset_of!`.
- `sys::socket::sockaddr_storage_to_addr`, `offset_of!`, and `Errno::clear` are
no longer `unsafe`.
- `SockAddr::as_ffi_pair`,`sys::socket::sockaddr_storage_to_addr`, `offset_of!`,
and `Errno::clear` are no longer `unsafe`.
(#[1244](https://github.com/nix-rust/nix/pull/1244))
- Several `Inotify` methods now take `self` by value instead of by reference
(#[1244](https://github.com/nix-rust/nix/pull/1244))
- `nix::poll::ppoll`: `timeout` parameter is now optional, None is equivalent for infinite timeout.
### Fixed
- Fixed `getsockopt`. The old code produced UB which triggers a panic with
Rust 1.44.0.
(#[1214](https://github.com/nix-rust/nix/pull/1214))
- Fixed a bug in nix::unistd that would result in an infinite loop
when a group or user lookup required a buffer larger than
16KB. (#[1198](https://github.com/nix-rust/nix/pull/1198))
- Fixed unaligned casting of `cmsg_data` to `af_alg_iv` (#[1206](https://github.com/nix-rust/nix/pull/1206))
- Fixed `readlink`/`readlinkat` when reading symlinks longer than `PATH_MAX` (#[1231](https://github.com/nix-rust/nix/pull/1231))
- `PollFd`, `EpollEvent`, `IpMembershipRequest`, `Ipv6MembershipRequest`,
`TimeVal`, and `IoVec` are now `repr(transparent)`. This is required for
correctness's sake across all architectures and compilers, though now bugs
have been reported so far.
(#[1243](https://github.com/nix-rust/nix/pull/1243))
- Fixed unaligned pointer read in `Inotify::read_events`.
(#[1244](https://github.com/nix-rust/nix/pull/1244))
### Removed

(#[1215](https://github.com/nix-rust/nix/pull/1215))
- Removed `sys::termios::{get_libc_termios, get_libc_termios_mut, update_wrapper`
from the public API. These were previously hidden in the docs but still usable
by downstream.
(#[1235](https://github.com/nix-rust/nix/pull/1235))
- Nix no longer implements `NixPath` for `Option<P> where P: NixPath`. Most
Nix functions that accept `NixPath` arguments can't do anything useful with
`None`. The exceptions (`mount` and `quotactl_sync`) already take explicitly
optional arguments.
(#[1242](https://github.com/nix-rust/nix/pull/1242))
- Removed `unistd::daemon` and `unistd::pipe2` on OSX and ios
(#[1255](https://github.com/nix-rust/nix/pull/1255))

- Added optional `Signal` argument to `ptrace::{detach, syscall}` for signal
injection. ([#1083](https://github.com/nix-rust/nix/pull/1083))
### Changed
- `sys::termios::BaudRate` now implements `TryFrom<speed_t>` instead of
`From<speed_t>`. The old `From` implementation would panic on failure.

- `sys::socket::ControlMessage::ScmCredentials` and
`sys::socket::ControlMessageOwned::ScmCredentials` now wrap `UnixCredentials`

([#1160](https://github.com/nix-rust/nix/pull/1160))
- `sys::socket::recvmsg` now takes a plain `Vec` instead of a `CmsgBuffer`
implementor. If you were already using `cmsg_space!`, then you needn't worry.
([#1156](https://github.com/nix-rust/nix/pull/1156))
- `sys::socket::recvfrom` now returns
`Result<(usize, Option<SockAddr>)>` instead of `Result<(usize, SockAddr)>`.

([#1109](https://github.com/nix-rust/nix/pull/1109))
```rust
# use nix::fcntl::{readlink, readlinkat};
let _: OsString = readlink(&path);
let _: OsString = readlinkat(dirfd, &path);
```

`ForkResult::is_child`, `ForkResult::is_parent`, `Gid::as_raw`,
`Uid::is_root`, `Uid::as_raw`, `Pid::as_raw`, and `PollFd::revents` now take
`self` by value.
([#1107](https://github.com/nix-rust/nix/pull/1107))

edition without importing helper macros on Linux targets.
([#1066](https://github.com/nix-rust/nix/pull/1066))
For example, in Rust 2018, the `ioctl_read_bad!` macro can now be imported
without importing the `convert_ioctl_res!` macro.
```rust
use nix::ioctl_read_bad;
ioctl_read_bad!(tcgets, libc::TCGETS, libc::termios);
```
### Changed
- Changed some public types from reexports of libc types like `uint32_t` to the

```
By replacing it with code like this:
```rust
if let ControlMessageOwned::ScmRights(fds) = cmsg {
```
([#1020](https://github.com/nix-rust/nix/pull/1020))
- Replaced `CmsgSpace` with the `cmsg_space` macro.

edition without importing helper macros for BSD targets.
([#1041](https://github.com/nix-rust/nix/pull/1041))
For example, in Rust 2018, the `ioctl_read_bad!` macro can now be imported
without importing the `convert_ioctl_res!` macro.
```rust
use nix::ioctl_read_bad;
ioctl_read_bad!(tcgets, libc::TCGETS, libc::termios);
```
### Removed
- `Daemon`, `NOTE_REAP`, and `NOTE_EXIT_REPARENTED` are now deprecated on OSX
and iOS.

`PTRACE_SETFPREGS` have been removed from some platforms where they never
should've been defined in the first place.

`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))

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))

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))

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`

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.

`::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))

- `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))

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.
