(https://github.com/tokio-rs/mio/commit/f5017fae8a3d3bb4b4cada25b01a2d76a406badc).## Fixes* Incorrect assumption of the layout of `std::net::SocketAddr`. Previously Mio  would assume that `SocketAddrV{4,6}` had the same layout as  `libc::sockaddr_in(6)`, however this is not guaranteed by the standard  library.  (https://github.com/tokio-rs/mio/commit/152e0751f0be1c9b0cbd6778645b76bcb0eba93c).* Also bumped the miow dependency to version 0.3.6 to solve the same problem as  above.# 0.7.5## Added* `TcpSocket::get_localaddr()` retrieves local address  (https://github.com/tokio-rs/mio/commit/b41a022b2242eef1969c70c8ba93e04c528dba47).* `TcpSocket::set_reuseport()` & `TcpSocket::get_reuseport()` configures and reads `SO_REUSEPORT`  (https://github.com/tokio-rs/mio/commit/183bbe409ab69cbf9db41d0263b41ec86202d9a0).* `unix:pipe()` a wrapper around pipe(2) sys call  (https://github.com/tokio-rs/mio/commit/2b7c0967a7362303946deb3d4ca2ae507af6c72d).* Add a check that a single Waker is active per Poll instance (only in debug mode)  (https://github.com/tokio-rs/mio/commit/f4874f28b32efcf4841691884c65a89734d96a56).* Added `Interest:remove()`  (https://github.com/tokio-rs/mio/commit/b8639c3d9ac07bb7e2e27685680c8a6510fa1357).# 0.7.4## Fixes* lost "socket closed" events on windows  (https://github.com/tokio-rs/mio/commit/50c299aca56c4a26e5ed20c283007239fbe6a7a7).## Added* `TcpSocket::set_linger()` configures SO_LINGER  (https://github.com/tokio-rs/mio/commit/3b4096565c1a879f651b8f8282ecdcbdbd5c92d3).# 0.7.3## Added* `TcpSocket` for configuring a TCP socket before connecting or listening  (https://github.com/tokio-rs/mio/commit/5b09e60d0f64419b989bda88c86a3147334a03b3).# 0.7.2## Added* Windows named pipe support.  (https://github.com/tokio-rs/mio/commit/52e8c2220e87696d20f13561402bcaabba4136ed).# 0.7.1## Reduced support for 32-bit Apple targetsIn January 2020 Rust reduced its support for 32-bit Apple targets(https://blog.rust-lang.org/2020/01/03/reducing-support-for-32-bit-apple-targets.html).Starting with v0.7.1 Mio will do the same as we're no longer checking 32 bitiOS/macOS on our CI.## Added* Support for illumos  (https://github.com/tokio-rs/mio/commit/976f2354d0e8fbbb64fba3bf017d7131f9c369a0).* Report `epoll(2)`'s `EPOLLERR` event as `Event::is_write_closed` if it's the  only event  (https://github.com/tokio-rs/mio/commit/0c77b5712d675eeb9bd43928b5dd7d22b2c7ac0c).* Optimised event::Iter::{size_hint, count}  (https://github.com/tokio-rs/mio/commit/40df934a11b05233a7796c4de19a4ee06bc4e03e).## Fixed* Work around Linux kernel < 2.6.37 bug on 32-bits making timeouts longer then  ~30 minutes effectively infinite  (https://github.com/tokio-rs/mio/commit/d555991f5ee81f6c1eec0fe481557d3d5b8d5ff4).* Set `SO_NOSIGPIPE` on all sockets (not just UDP) on for Apple targets  (https://github.com/tokio-rs/mio/commit/b8bbdcb0d3236f4c4acb257996d42a88dc9987d9).* Properly handle `POLL_ABORT` on Windows  (https://github.com/tokio-rs/mio/commit/a98da62b3ed1eeed1770aaca12f46d647e4fa749).* Improved error handling around failing `SIO_BASE_HANDLE` calls on Windows  (https://github.com/tokio-rs/mio/commit/b15fc18458a79ef8a51f73effa92548650f4e5dc).## Changed* On NetBSD we now use `accept4(2)`  (https://github.com/tokio-rs/mio/commit/4e306addc7144f2e02a7e8397c220b179a006a19).* The package uploaded to crates.io should be slightly smaller  (https://github.com/tokio-rs/mio/commit/eef8d3b9500bc0db957cd1ac68ee128ebc68351f).## Removed* Dependency on `lazy_static` on Windows  (https://github.com/tokio-rs/mio/commit/57e4c2a8ac153bc7bb87829e22cf0a21e3927e8a).# 0.7.0Version 0.7 of Mio contains various major changes compared to version 0.6.Overall a large number of API changes have been made to reduce the complexity ofthe implementation and remove overhead where possible.Please refer to the [blog post about0.7-alpha.1](https://tokio.rs/blog/2019-12-mio-v0.7-alpha.1/) for additionalinformation.## Added* `Interest` structure that replaces `Ready` in registering event sources.* `Registry` structure that separates the registering and polling functionality.* `Waker` structure that allows another thread to wake a thread polling `Poll`.* Unix Domain Socket (UDS) types: `UnixDatagram`, `UnixListener` and  `UnixStream`.## Removed* All code deprecated in 0.6 was removed in 0.7.* Support for Fuchsia was removed as the code was unmaintained.* Support for Bitrig was removed, rustc dropped support for it also.* `UnixReady` was merged into `Ready`.* Custom user-space readiness queue was removed, this includes the public  `Registration` and `SetReadiness` types.* `PollOpt` was removed and all registrations use edge-triggers. See the upgrade  guide on how to process event using edge-triggers.* The network types (types in the `net` module) now support only the same API as  found in the standard library, various methods on the types were removed.* `TcpStream` now supports vectored I/O.* `Poll::poll_interruptible` was removed. Instead `Poll::poll` will now return  an error if one occurs.* `From<usize>` is removed from `Token`, the internal field is still public, so  `Token(my_token)` can still be used.## Changed* Various documentation improvements were made around correct usage of `Poll`  and registered event sources. It is recommended to reread the documentation of  at least `event::Source` and `Poll`.* Mio now uses Rust 2018 and rustfmt for all code.* `Event` was changed to be a wrapper around the OS event. This means it can be  significantly larger on some OSs.* `Ready` was removed and replaced with various `is_*` methods on `Event`. For  example instead checking for readable readiness using  `Event::ready().is_readable()`, you would call `Event::is_readable()`.* `Ready::is_hup` was removed in favour of `Event::is_read_closed` and  `Event::is_write_closed`.* The Iterator implementation of `Events` was changed to return `&Event`.* `Evented` was renamed to `event::Source` and now takes mutable reference to  the source.* Minimum supported Rust version was increased to 1.39.* By default Mio now uses a shim implementation. To enable the full  implementation, that uses the OS, enable the `os-oll` feature. To enable the  network types use `tcp`, `udp` and/or `uds`. For more documentation on the  features see the `feature` module in the API documentation (requires the  `extra-docs` feature).* The entire Windows implementation was rewritten.* Various optimisation were made to reduce the number of system calls in  creating and using sockets, e.g. making use of `accept4(2)`.* The `fmt::Debug` implementation of `Events` is now actually useful as it  prints all `Event`s.# 0.6.23 (Dec 01, 2020)### Changed- **MSRV**: Increased the MSRV from 1.18.0 (Jun 8, 2017) to 1.31.0 (Dec 6,  2018)  (https://github.com/tokio-rs/mio/commit/4879e0d32ddfd98e762fc87240e594a3ad8fca30).### Fixed- Work around Linux kernel < 2.6.37 bug on 32-bits making timeouts longer then  ~30 minutes effectively infinite  (https://github.com/tokio-rs/mio/commit/e7cba59950e9c9fa6194e29b5b1e72029e3df455).- Update miow and net2 dependencies to get rid of invalid memory layout assumption  (https://github.com/tokio-rs/mio/commit/13f02ac0a86d7c0c0001e5ff8960a0b4340d075c).# 0.6.22 (May 01, 2020)### Added- Add support for illumos target (#1294)# 0.6.21 (November 27, 2019)### Fixed- remove `=` dependency on `cfg-if`.# 0.6.20 (November 21, 2019)### Fixed- Use default IOCP concurrency value (#1161).- setting FD_CLOEXEC in pipe (#1095).# 0.6.19 (May 28, 2018)### Fixed- Do not trigger HUP events on kqueue platforms (#958).# 0.6.18 (May 24, 2018)### Fixed- Fix compilation on kqueue platforms with 32bit C long (#948).# 0.6.17 (May 15, 2018)### Fixed- Don't report `RDHUP` as `HUP` (#939)- Fix lazycell related compilation issues.- Fix EPOLLPRI conflicting with READABLE- Abort process on ref count overflows### Added- Define PRI on all targets# 0.6.16 (September 5, 2018)* Add EPOLLPRI readiness to UnixReady on supported platforms (#867)* Reduce spurious awaken calls (#875)# 0.6.15 (July 3, 2018)* Implement `Evented` for containers (#840).* Fix android-aarch64 build (#850).# 0.6.14 (March 8, 2018)* Add `Poll::poll_interruptible` (#811)* Add `Ready::all` and `usize` conversions (#825)# 0.6.13 (February 5, 2018)* Fix build on DragonFlyBSD.* Add `TcpListener::from_std` that does not require the socket addr.* Deprecate `TcpListener::from_listener` in favor of from_std.# 0.6.12 (January 5, 2018)* Add `TcpStream::peek` function (#773).* Raise minimum Rust version to 1.18.0.* `Poll`: retry select() when interrupted by a signal (#742).* Deprecate `Events` index access (#713).* Add `Events::clear` (#782).* Add support for `lio_listio` (#780).# 0.6.11 (October 25, 2017)* Allow register to take empty interest (#640).* Fix bug with TCP errors on windows (#725).* Add TcpListener::accept_std (#733).* Update IoVec to fix soundness bug -- includes behavior change.
