CHANGES:

Note: Eio 0.4 drops compatibility with OCaml 4.12+domains. Use OCaml 5.0.0~alpha1 instead.

API changes:

• Eio.Dir has gone. Use Eio.Path instead (@talex5 #266 #270).

• Eio_unix.FD.{take,peek} were renamed to take_opt/peek_opt to make way for non-optional versions.

New features:

• Fiber-local storage (@SquidDev #256).
  Attach key/value bindings to fibers. These are inherited across forks.

• Eio.Path.{unlink,rmdir,rename} (@talex5 #264 #265).

• Eio_main.run can now return a value (@talex5 #263).
  This is useful for e.g. cmdliner.

• Eio_unix.socketpair (@talex5 #260).

• Fiber.fork_daemon (@talex5 #252).
  Create a helper fiber that does not prevent the switch from exiting.

• Add Fiber.{iter,map,filter,fiter_map} (@talex5 #248 #250).
  These are concurrent versions of the corresponding operations in List.

Bug fixes:

• Fix scheduling fairness in luv backend (@talex5 #269).

• Implement remaining shutdown commands for luv (@talex5 #268).

• Fix IPv6 support with uring backend (@haesbaert #261 #262).

• Use Eio.Net.Connection_reset exception in more places (@talex5 #257).

• Report use of closed FDs better (@talex5 #255).
  Using a closed FD could previously cause the whole event loop to exit.

• Some fixes for cancellation (@talex5 #254).

• Ensure Buf_write still flushes if an exception is raised (@talex5 #246).

• Do not allow close on accept_fork socket (@talex5 #245).

Documentation:

• Document integrations with Unix, Lwt and Async (@talex5 #247).

• Add a Dockerfile for easy testing (@talex5 #224).
