CHANGES:

API changes:

- `Net.accept_sub` is deprecated in favour of `accept_fork` (@talex5 ocaml-multicore/eio#240).
  `Fiber.fork_on_accept`, which it used internally, has been removed.

- Allow short writes in `Read_source_buffer` (@talex5 ocaml-multicore/eio#239).
  The reader is no longer required to consume all the data in one go.
  Also, add `Linux_eio.Low_level.writev_single` to expose this behaviour directly.

- `Eio.Unix_perm` is now `Eio.Dir.Unix_perm`.

New features:

- Add `Eio.Mutex` (@TheLortex @talex5 ocaml-multicore/eio#223).

- Add `Eio.Buf_write` (@talex5 ocaml-multicore/eio#235).
  This is a buffered writer for Eio sinks, based on Faraday.

- Add `Eio_mock` library for testing (@talex5 ocaml-multicore/eio#228).
  At the moment it has mock flows and networks.

- Add `Eio_mock.Backend` (@talex5 ocaml-multicore/eio#237 ocaml-multicore/eio#238).
  Allows running tests without needing a dependency on eio_main.
  Also, as it is single-threaded, it can detect deadlocks in test code instead of just hanging.

- Add `Buf_read.{of_buffer, of_string, parse_string{,_exn}, return}` (@talex5 ocaml-multicore/eio#225).

- Add `<*>` combinator to `Buf_read.Syntax` (@talex5 ocaml-multicore/eio#227).

- Add `Eio.Dir.read_dir` (@patricoferris @talex5 ocaml-multicore/eio#207 ocaml-multicore/eio#218 ocaml-multicore/eio#219)

Performance:

- Add `Buf_read` benchmark and optimise it a bit (@talex5 ocaml-multicore/eio#230).

- Inline `Buf_read.consume` to improve performance (@talex5 ocaml-multicore/eio#232).

Bug fixes / minor changes:

- Allow IO to happen even if a fiber keeps yielding (@TheLortex @talex5 ocaml-multicore/eio#213).

- Fallback for `traceln` without an effect handler (@talex5 ocaml-multicore/eio#226).
  `traceln` now works outside of an event loop too.

- Check for cancellation when creating a non-protected child context (@talex5 ocaml-multicore/eio#222).

- eio_linux: handle EINTR when calling `getrandom` (@bikallem ocaml-multicore/eio#212).

- Update to cmdliner.1.1.0 (@talex5 ocaml-multicore/eio#190).
