104
105## Fixes
106
107* Incorrect assumption of the layout of `std::net::SocketAddr`. Previously Mio
108  would assume that `SocketAddrV{4,6}` had the same layout as
109  `libc::sockaddr_in(6)`, however this is not guaranteed by the standard
110  library.
111  (https://github.com/tokio-rs/mio/commit/152e0751f0be1c9b0cbd6778645b76bcb0eba93c).
112* Also bumped the miow dependency to version 0.3.6 to solve the same problem as

158## Reduced support for 32-bit Apple targets
159
160In January 2020 Rust reduced its support for 32-bit Apple targets
161(https://blog.rust-lang.org/2020/01/03/reducing-support-for-32-bit-apple-targets.html).
162Starting with v0.7.1 Mio will do the same as we're no longer checking 32 bit
163iOS/macOS on our CI.
164
165## Added
166
167* Support for illumos
168  (https://github.com/tokio-rs/mio/commit/976f2354d0e8fbbb64fba3bf017d7131f9c369a0).
169* Report `epoll(2)`'s `EPOLLERR` event as `Event::is_write_closed` if it's the
170  only event
171  (https://github.com/tokio-rs/mio/commit/0c77b5712d675eeb9bd43928b5dd7d22b2c7ac0c).
172* Optimised event::Iter::{size_hint, count}
173  (https://github.com/tokio-rs/mio/commit/40df934a11b05233a7796c4de19a4ee06bc4e03e).
174
175## Fixed
176
177* Work around Linux kernel < 2.6.37 bug on 32-bits making timeouts longer then
178  ~30 minutes effectively infinite
179  (https://github.com/tokio-rs/mio/commit/d555991f5ee81f6c1eec0fe481557d3d5b8d5ff4).
180* Set `SO_NOSIGPIPE` on all sockets (not just UDP) on for Apple targets
181  (https://github.com/tokio-rs/mio/commit/b8bbdcb0d3236f4c4acb257996d42a88dc9987d9).
182* Properly handle `POLL_ABORT` on Windows
183  (https://github.com/tokio-rs/mio/commit/a98da62b3ed1eeed1770aaca12f46d647e4fa749).
184* Improved error handling around failing `SIO_BASE_HANDLE` calls on Windows
185  (https://github.com/tokio-rs/mio/commit/b15fc18458a79ef8a51f73effa92548650f4e5dc).
186
187## Changed
188
189* On NetBSD we now use `accept4(2)`
190  (https://github.com/tokio-rs/mio/commit/4e306addc7144f2e02a7e8397c220b179a006a19).
191* The package uploaded to crates.io should be slightly smaller
192  (https://github.com/tokio-rs/mio/commit/eef8d3b9500bc0db957cd1ac68ee128ebc68351f).
193
194## Removed
195
196* Dependency on `lazy_static` on Windows
197  (https://github.com/tokio-rs/mio/commit/57e4c2a8ac153bc7bb87829e22cf0a21e3927e8a).
198
199# 0.7.0
200
201Version 0.7 of Mio contains various major changes compared to version 0.6.
202Overall a large number of API changes have been made to reduce the complexity of
203the implementation and remove overhead where possible.
204
205Please refer to the [blog post about
2060.7-alpha.1](https://tokio.rs/blog/2019-12-mio-v0.7-alpha.1/) for additional
207information.
208
209## Added
210
211* `Interest` structure that replaces `Ready` in registering event sources.
212* `Registry` structure that separates the registering and polling functionality.
213* `Waker` structure that allows another thread to wake a thread polling `Poll`.
214* Unix Domain Socket (UDS) types: `UnixDatagram`, `UnixListener` and
215  `UnixStream`.
216
217## Removed
218
219* All code deprecated in 0.6 was removed in 0.7.
220* Support for Fuchsia was removed as the code was unmaintained.
221* Support for Bitrig was removed, rustc dropped support for it also.
222* `UnixReady` was merged into `Ready`.
223* Custom user-space readiness queue was removed, this includes the public
224  `Registration` and `SetReadiness` types.
225* `PollOpt` was removed and all registrations use edge-triggers. See the upgrade
226  guide on how to process event using edge-triggers.
227* The network types (types in the `net` module) now support only the same API as
228  found in the standard library, various methods on the types were removed.
229* `TcpStream` now supports vectored I/O.
230* `Poll::poll_interruptible` was removed. Instead `Poll::poll` will now return
231  an error if one occurs.
232* `From<usize>` is removed from `Token`, the internal field is still public, so
233  `Token(my_token)` can still be used.
234
235## Changed
236
237* Various documentation improvements were made around correct usage of `Poll`
238  and registered event sources. It is recommended to reread the documentation of
239  at least `event::Source` and `Poll`.
240* Mio now uses Rust 2018 and rustfmt for all code.
241* `Event` was changed to be a wrapper around the OS event. This means it can be
242  significantly larger on some OSes.
243* `Ready` was removed and replaced with various `is_*` methods on `Event`. For
244  example instead checking for readable readiness using
245  `Event::ready().is_readable()`, you would call `Event::is_readable()`.
246* `Ready::is_hup` was removed in favour of `Event::is_read_closed` and
247  `Event::is_write_closed`.
248* The Iterator implementation of `Events` was changed to return `&Event`.
249* `Evented` was renamed to `event::Source` and now takes mutable reference to
250  the source.
251* Minimum supported Rust version was increased to 1.39.
252* By default Mio now uses a shim implementation. To enable the full
253  implementation, that uses the OS, enable the `os-oll` feature. To enable the
254  network types use `tcp`, `udp` and/or `uds`. For more documentation on the
255  features see the `feature` module in the API documentation (requires the
256  `extra-docs` feature).
257* The entire Windows implementation was rewritten.
258* Various optimisation were made to reduce the number of system calls in
259  creating and using sockets, e.g. making use of `accept4(2)`.
260* The `fmt::Debug` implementation of `Events` is now actually useful as it
261  prints all `Event`s.
262

430# 0.6.0 (September 2, 2016)
431
432* Shift primary API towards `Poll`

445* Polled events are now retrieved via `Events` type.
446* Implement `std::error::Error` for `TimerError`
447* Relax `Send` bound on notify messages.

454
455* Windows support (#239)
456* NetBSD support (#306)
457* Android support (#295)
458* Don't re-export bytes types
459* Renamed `EventLoop::register_opt` to `EventLoop::register` (#257)
460* `EventLoopConfig` is now a builder instead of having public struct fields. It
461  is also no longer `Copy`. (#259)
462* `TcpSocket` is no longer exported in the public API (#262)
463* Integrate with net2. (#262)
464* `TcpListener` now returns the remote peer address from `accept` as well (#275)
465* The `UdpSocket::{send_to, recv_from}` methods are no longer generic over `Buf`
466  or `MutBuf` but instead take slices directly. The return types have also been
467  updated to return the number of bytes transferred. (#260)
468* Fix bug with kqueue where an error on registration prevented the
469  changelist from getting flushed (#276)
470* Support sending/receiving FDs over UNIX sockets (#291)
471* Mio's socket types are permanently associated with an EventLoop (#308)
472* Reduce unnecessary poll wakeups (#314)
