# 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)

- 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)
