CHANGES:

Changes:

- Update to OCaml 5.0.0~beta1 (@anmonteiro @talex5 ocaml-multicore/eio#346).

- Add API for seekable read/writes (@nojb ocaml-multicore/eio#307).

- Add `Flow.write` (@haesbaert ocaml-multicore/eio#318).
  This provides an optimised alternative to `copy` in the case where you are writing from a buffer.

- Add `Net.with_tcp_connect` (@bikallem ocaml-multicore/eio#302).
  Convenience function for opening a TCP connection.

- Add `Eio.Time.Timeout` (@talex5 ocaml-multicore/eio#320).
  Makes it easier to pass timeouts around.

- Add `Eio_mock.Clock` (@talex5 ocaml-multicore/eio#328).
  Control time in tests.

- Add `Buf_read.take_while1` and `skip_while1` (@bikallem ocaml-multicore/eio#309).
  These fail if no characters match.

- Make the type parameter for `Promise.t` covariant (@anmonteiro ocaml-multicore/eio#300).

- Move list functions into a dedicated submodule (@raphael-proust ocaml-multicore/eio#315).

- Direct implementation of `Flow.source_string` (@c-cube ocaml-multicore/eio#317).
  Slightly faster.

Bug fixes:

- `Condition.broadcast` must interlock as well (@haesbaert ocaml-multicore/eio#324).

- Split the reads into no more than 2^32-1 for luv (@haesbaert @talex5 @EduardoRFS ocaml-multicore/eio#343).
  Luv uses a 32 bit int for buffer sizes and wraps if the value passed is too big.

- eio_luv: allow `Net.connect` to be cancelled (@talex5 @nojb ocaml-multicore/eio#311).

- eio_main: Use dedicated log source (@anmonteiro ocaml-multicore/eio#326).

- linux_eio: fix kernel version number in log message (@talex5 @nojb ocaml-multicore/eio#314).

- Account for stack differences in the socketpair test (issue ocaml-multicore/eio#312) (@haesbaert ocaml-multicore/eio#313).

Documentation:

- Add Best Practices section to README (@talex5 ocaml-multicore/eio#299).

- Documentation improvements (@talex5 ocaml-multicore/eio#295 ocaml-multicore/eio#337).
