CHANGES:

New features:

• Add Eio.Path.symlink (@patricoferris Add symlink support ocaml-multicore/eio#715, reviewed by @talex5).

• Add Eio.Pool.use ~never_block (@SGrondin Add Eio.Pool.use ~never_block ocaml-multicore/eio#657, reviewed by @talex5).

• Add Eio_unix.Net.import_socket_listening (@alyssais Add Eio_unix.Net.import_socket_listening ocaml-multicore/eio#733).

• Add Eio.Time.Timeout.sleep (@talex5 Add Timeout.sleep ocaml-multicore/eio#726).

Documentation:

• Add examples/fs showing how to walk a directory tree (@talex5 Add examples/fs showing how to walk a directory tree ocaml-multicore/eio#730).

• README: explain that read_all reads until shutdown (@talex5 README: explain that read_all reads until shutdown ocaml-multicore/eio#717, reported by @Wenke-D).

• Use long dash in README title (@lucperkins Long dash in README title ocaml-multicore/eio#718).

Linux backend:

• Require Linux >= 5.15 (@talex5 eio_linux: require Linux >= 5.15 ocaml-multicore/eio#720, reviewed by @SGrondin and @avsm).
  Removes a work-around that required checking whether every flow was a tty.

• Don't call submit immediately before wait (@talex5 eio_linux: don't call submit immediately before wait ocaml-multicore/eio#728).
  This is slightly faster and makes the traces clearer.

• Don't record submit events when there's nothing to submit (@talex5 eio_linux: don't record submit events when there's nothing to submit ocaml-multicore/eio#729).
  Makes the traces a bit clearer.

• Split flow into its own file (@talex5 eio_linux: split flow into its own file ocaml-multicore/eio#727).

• Add work-around for signals race (@talex5 eio_linux: add work-around for signals race ocaml-multicore/eio#734).

POSIX backend:

• Add _BSD_SOURCE flag to fix build on OpenBSD (@prgbln Add _BSD_SOURCE flag to fix eio_posix on OpenBSD. ocaml-multicore/eio#722).

• Fix sandboxed path resolution on OpenBSD (@jebrosen eio_posix: fix filesystem tests on OpenBSD ocaml-multicore/eio#723, reviewed by @talex5).
  OpenBSD uses ELOOP when opening a symlink with O_NOFOLLOW.

Build and test:

• Benchmarks: record uname, Eio backend, and number of cores (@talex5 Benchmarks: record uname, Eio backend, and number of cores ocaml-multicore/eio#719).

• Update to MDX 2.4.1 for OCaml 5.2 (@talex5 Update to MDX 2.4.1 ocaml-multicore/eio#712).

[talex5]

The only CI failure is extras/opam-2.0-ocaml-5.2, which looks unrelated to this package (conf-pkg-config.3 failed to build).
