77
78## Fixes
79
80* Incorrect assumption of the layout of `std::net::SocketAddr`. Previously Mio
81  would assume that `SocketAddrV{4,6}` had the same layout as
82  `libc::sockaddr_in(6)`, however this is not guaranteed by the standard
83  library.
84  (https://github.com/tokio-rs/mio/commit/152e0751f0be1c9b0cbd6778645b76bcb0eba93c).
85* Also bumped the miow dependency to version 0.3.6 to solve the same problem as

131## Reduced support for 32-bit Apple targets
132
133In January 2020 Rust reduced its support for 32-bit Apple targets
134(https://blog.rust-lang.org/2020/01/03/reducing-support-for-32-bit-apple-targets.html).
135Starting with v0.7.1 Mio will do the same as we're no longer checking 32 bit
136iOS/macOS on our CI.
137
138## Added
139
140* Support for illumos
141  (https://github.com/tokio-rs/mio/commit/976f2354d0e8fbbb64fba3bf017d7131f9c369a0).
142* Report `epoll(2)`'s `EPOLLERR` event as `Event::is_write_closed` if it's the
143  only event
144  (https://github.com/tokio-rs/mio/commit/0c77b5712d675eeb9bd43928b5dd7d22b2c7ac0c).
145* Optimised event::Iter::{size_hint, count}
146  (https://github.com/tokio-rs/mio/commit/40df934a11b05233a7796c4de19a4ee06bc4e03e).
147
148## Fixed
149
150* Work around Linux kernel < 2.6.37 bug on 32-bits making timeouts longer then
151  ~30 minutes effectively infinite
152  (https://github.com/tokio-rs/mio/commit/d555991f5ee81f6c1eec0fe481557d3d5b8d5ff4).
153* Set `SO_NOSIGPIPE` on all sockets (not just UDP) on for Apple targets
154  (https://github.com/tokio-rs/mio/commit/b8bbdcb0d3236f4c4acb257996d42a88dc9987d9).
155* Properly handle `POLL_ABORT` on Windows
156  (https://github.com/tokio-rs/mio/commit/a98da62b3ed1eeed1770aaca12f46d647e4fa749).
157* Improved error handling around failing `SIO_BASE_HANDLE` calls on Windows
158  (https://github.com/tokio-rs/mio/commit/b15fc18458a79ef8a51f73effa92548650f4e5dc).
159
160## Changed
161
162* On NetBSD we now use `accept4(2)`
163  (https://github.com/tokio-rs/mio/commit/4e306addc7144f2e02a7e8397c220b179a006a19).
164* The package uploaded to crates.io should be slightly smaller
165  (https://github.com/tokio-rs/mio/commit/eef8d3b9500bc0db957cd1ac68ee128ebc68351f).
166
167## Removed
168
169* Dependency on `lazy_static` on Windows
170  (https://github.com/tokio-rs/mio/commit/57e4c2a8ac153bc7bb87829e22cf0a21e3927e8a).
171
172# 0.7.0
173
174Version 0.7 of Mio contains various major changes compared to version 0.6.
175Overall a large number of API changes have been made to reduce the complexity of
176the implementation and remove overhead where possible.
177
178Please refer to the [blog post about
1790.7-alpha.1](https://tokio.rs/blog/2019-12-mio-v0.7-alpha.1/) for additional
180information.
181
182## Added
183
184* `Interest` structure that replaces `Ready` in registering event sources.
185* `Registry` structure that separates the registering and polling functionality.
186* `Waker` structure that allows another thread to wake a thread polling `Poll`.
187* Unix Domain Socket (UDS) types: `UnixDatagram`, `UnixListener` and
188  `UnixStream`.
189
190## Removed
191
192* All code deprecated in 0.6 was removed in 0.7.
193* Support for Fuchsia was removed as the code was unmaintained.
194* Support for Bitrig was removed, rustc dropped support for it also.
195* `UnixReady` was merged into `Ready`.
196* Custom user-space readiness queue was removed, this includes the public
197  `Registration` and `SetReadiness` types.
198* `PollOpt` was removed and all registrations use edge-triggers. See the upgrade
199  guide on how to process event using edge-triggers.
200* The network types (types in the `net` module) now support only the same API as
201  found in the standard library, various methods on the types were removed.
202* `TcpStream` now supports vectored I/O.
203* `Poll::poll_interruptible` was removed. Instead `Poll::poll` will now return
204  an error if one occurs.
205* `From<usize>` is removed from `Token`, the internal field is still public, so
206  `Token(my_token)` can still be used.
207
208## Changed
209
210* Various documentation improvements were made around correct usage of `Poll`
211  and registered event sources. It is recommended to reread the documentation of
212  at least `event::Source` and `Poll`.
213* Mio now uses Rust 2018 and rustfmt for all code.
214* `Event` was changed to be a wrapper around the OS event. This means it can be
215  significantly larger on some OSes.
216* `Ready` was removed and replaced with various `is_*` methods on `Event`. For
217  example instead checking for readable readiness using
218  `Event::ready().is_readable()`, you would call `Event::is_readable()`.
219* `Ready::is_hup` was removed in favour of `Event::is_read_closed` and
220  `Event::is_write_closed`.
221* The Iterator implementation of `Events` was changed to return `&Event`.
222* `Evented` was renamed to `event::Source` and now takes mutable reference to
223  the source.
224* Minimum supported Rust version was increased to 1.39.
225* By default Mio now uses a shim implementation. To enable the full
226  implementation, that uses the OS, enable the `os-oll` feature. To enable the
227  network types use `tcp`, `udp` and/or `uds`. For more documentation on the
228  features see the `feature` module in the API documentation (requires the
229  `extra-docs` feature).
230* The entire Windows implementation was rewritten.
231* Various optimisation were made to reduce the number of system calls in
232  creating and using sockets, e.g. making use of `accept4(2)`.
233* The `fmt::Debug` implementation of `Events` is now actually useful as it
234  prints all `Event`s.
235

419* Implement `std::error::Error` for `TimerError`
420* Relax `Send` bound on notify messages.

427
428* Windows support (#239)
429* NetBSD support (#306)
430* Android support (#295)
431* Don't re-export bytes types
432* Renamed `EventLoop::register_opt` to `EventLoop::register` (#257)
433* `EventLoopConfig` is now a builder instead of having public struct fields. It
434  is also no longer `Copy`. (#259)
435* `TcpSocket` is no longer exported in the public API (#262)
436* Integrate with net2. (#262)
437* `TcpListener` now returns the remote peer address from `accept` as well (#275)
438* The `UdpSocket::{send_to, recv_from}` methods are no longer generic over `Buf`
439  or `MutBuf` but instead take slices directly. The return types have also been
440  updated to return the number of bytes transferred. (#260)
441* Fix bug with kqueue where an error on registration prevented the
442  changelist from getting flushed (#276)
443* Support sending/receiving FDs over UNIX sockets (#291)
444* Mio's socket types are permanently associated with an EventLoop (#308)
445* Reduce unnecessary poll wakeups (#314)
