# Version 3.4.0
- Add the ability to identify whether socket connection has failed. (#185)
- On BSD, add the ability to wait on a process by its PID. Previously, it was
only possible to wait on a process by a `Child` object. (#180)
- On ESP-IDF, annotate `eventfd` initialization failures with a message
indicating the source of those failures. (#186)
# Version 3.3.2
- When AFD fails to initialize, the resulting error now references
the underlying system error. (#174)
# Version 3.3.1
- Bump `windows-sys` to v0.52.0. (#169)
# Version 3.3.0
- Automatically restarts polling when `ErrorKind::Interrupted` is returned, rather than relying on the user to handle it. (#164)
- Fix bad link in documentation for `Poller::wait()`. (#163)
# Version 3.2.0
- The `kqueue` backend previously allowed the following operations that other backends forbid. Now these operations result in an error: (#153)
- Inserting a source that was already inserted.
- Modifying/deleting a source that was not already inserted.
- Add support for Haiku OS. (#154)
# Version 3.1.0
- Add an `Event::new()` constructor to simplify creating `Event`s. (#149)
# Version 3.0.0
- Replace `libc` in all backends with the `rustix` crate (#108).
- Use `tracing` instead of `log` for logging (#119).
- **Breaking:** Rework the API to use I/O safety. Note that this makes several previously safe functions unsafe. (#123)
- Add support for the ESP-IDF platform. (#128)
- **Breaking:** Make `Event` partially opaque, and create a new `Events` struct for holding events. (#133)
- Add support for running `polling` in Linux containers without `eventfd` available. (#134)
- Specify the behavior when registered in multiple `Poller`s. (#136)
- **Breaking:** Use `c_int` from the standard library in `polling::os::kqueue` instead of defining our own. (#143)
- **Breaking:** Remove the useless `std` feature. (#147)
# Version 2.8.0
- Add functionality for posting events to the IOCP. (#101)
# Version 2.7.0
- Add edge/oneshot combination mode. (#96)
- Update windows-sys requirement from 0.45 to 0.48. (#103)
# Version 2.6.0
- Add level and edge triggered modes to the poller (#59)
- Support tvOS and watchOS (#60)
- Prevent large timeouts from causing panics on certain backends (#71)
- For certain BSDs, use `EVFILT_USER` to wake up the poller instead of a pipe (#73)
- For Solaris/illumos, use `port_send` to wake up the poller instead of a pipe (#74)
- Update `windows_sys` from 0.42 to 0.45 (#80)
- Expose other `kqueue` filter types (#83)
- Replace the Windows backend with a hand-written version, rather than bringing in a C dependency (#88)
# Version 2.5.2
- Update use of `libc::timespec` to prepare for future libc version (#55)
- Update use of `libc::kevent` to prepare for future libc version (#56)
- Add error message for Wepoll (#54)
# Version 2.5.1
- Fix the build error with MSRV on Windows
# Version 2.5.0
- Switch from `winapi` to `windows-sys` (#47)
# Version 2.4.0
- Fix the build error on illumos and Solaris (#43)
- Bump MSRV to 1.47 (#40)
- Optimize `Poller` internal representation (#40)
# Version 2.3.0
- Implement `AsRawFd` for `Poller` on most Unix systems (#39)
- Implement `AsRawHandle` for `Poller` on Windows (#39)
- Implement I/O safety traits on Rust 1.63+ (#39)
# Version 2.2.0
- Support VxWorks, Fuchsia and other Unix systems by using poll. (#26)
# Version 2.1.0
- Switch from `wepoll-sys` to `wepoll-ffi`.
# Version 2.0.3
- Update `cfg-if` dependency to 1.
# Version 2.0.2
- Replace manual pointer conversion with `as_ptr()` and `as_mut_ptr()`.
# Version 2.0.1
- Minor docs improvements.
# Version 2.0.0
- Add `Event` argument to `Poller::insert()`.
- Don't put fd/socket in non-blocking mode upon insertion.
- Rename `insert()`/`interest()`/`remove()` to `add()`/`modify()`/`delete()`.
- Replace `wepoll-sys-stjepang` with an `wepoll-sys`.
# Version 1.1.0
- Add "std" cargo feature.
# Version 1.0.3
- Remove `libc` dependency on Windows.
# Version 1.0.2
- Bump MSRV to 1.40.0
- Replace the `epoll_create1` hack with a cleaner solution.
- Pass timeout to `epoll_wait` to support systems without `timerfd`.
# Version 1.0.1

# Version 1.0.0
- Stabilize.
# Version 0.1.9
