====== Documentation ======
* Small fixes. (Nils André, #1001, #1006)
* Convert manual to mld. (#951, Antonin Décimo)
====== Other ======
* Many improbements to the CI. (Sora Morimoto, Idir Lankri, #986, #1009, #1011, #1013, #1014, #1016, #1020, #1021, #1023, #1024, #1025)

* Make C code pass the stricter checks of GCC 14. (Jerry James, #1004)
* Fix many many C warnings and other fixes. (Antonin Décimo, #1007, #1022)
===== 5.7.0 =====
====== Breaking API changes ======
* Lwt_result.catch now takes a function (unit -> 'a t) rather than a promise ('a t). (#965)
* Remove the deprecated Lwt.result type (use Stdlib.result instead). (#968)
* Remove the deprecated Lwt.make_value and Lwt.make_result functions (use Ok and Error instead). (#968)
* Remove the deprecated and unsafe waiter_of_wakener (keep the waiter around when you create the wakener instead). (#968)
* Remove the deprecated Lwt_stream.on_termination and Lwt_stream.on_terminate (bind to Lwt_stream.closed instead). (#968)
* Remove the deprecated Lwt_stream.result type (use Stdlib.result instead). (#968)
* Remove the deprecated Lwt_stream.map_exn function (use wrap_exn instead). (#968)
====== Additions ======
* Lwt.Exception_filter for enabling/disabling system-exception catching. (#964)
* Lwt.reraise an exception raising function which preserves backtraces, recommended for use in Lwt.catch. (#963)
* Expose Lwt_io.delete_recursively for deleting a directory and its content recursively. (#984, Antonin Décimo)
* Lwt_preemptive.run_in_main_dont_wait to run a function in the main preemptive thread but without waiting for the result. (Kate Deplaix, #960)
* Lwt_unix.handle_signal and Lwt_engine.forwards_signal to allow other IO libraries (such as Eio) to share signal handlers. (Thomas Leonard, #993, #991)
====== Build ======
* Remove unused dependency in dune file. (#969, Kate Deplaix)
* Fix some compilation warnings for C stubs with OCaml 5. (#976, Antonin Décimo)

* Fix race in worker loop. (Thomas Leonard, #993, #994)
* Fix marshall header size in Lwt_io.read_value. (Simmo Saan, #995)
====== Misc ======
* Resolve paused promises only once in main loop. This lets Lwt.pause behave identical to Lwt_unix.yield. (#917, Christopher Zimmermann, Favonia)
===== 5.6.1 =====
====== Fixes ======
* Fix null file descriptor being closed when used as redirection for standard fd of child processes. (#957, Antonin Décimo)
===== 5.6.0 =====
====== Installability ======
* Lwt is now compatible with OCaml 5.00. Lwt is now incompatible with OCaml 4.02. (#925, #923, Kate Deplaix, Patrick Ferris)
* Lwt is now incompatible with OCaml.4.07 and earlier. (#947, Hannes Mehnert, Tim McGilchrist)
* Lwt-unix is now compatible with OCaml 5.0.0. (#953, David Allsopp)
====== Additions ======
* In the Lwt_io module, add `?cloexec:bool` optional arguments to functions that create file descriptors (`pipe`). The `?cloexec` argument is simply forwarded to the wrapped Lwt_unix function. (#872, #911, Antonin Décimo)
* Add Lwt_result.error, Lwt_result.iter, and Lwt_result.iter_error for consistency with Stdlib. (#927, Antonin Décimo)
* Lwt_result.bind_error. (#943, Boning Dong)
* Add ?cloexec parameter to Lwt_io.pipe. (#911, Antonin Décimo)
====== Misc ======
* On Windows, make Lwt_process.create_process duplicate standard handles given to the child process if they're not inheritable, to mimic the behaviour of Unix.create_process. (#909, Antonin Décimo)
* Add missing dependency to `cppo` in lwt-react's opam file. (#946, Rizo I)

* Improve deprecation message for auto_yield. (#908, Seb Mondet)
* Fix mirage tutorial link. (#936, Tuomas Lukka)
* Fix issues in opam file. (#937, Andreas Hauptmann)
====== Fixes ======
* Fix win32_spawn leaking dev_null fd in the parent process. (#906, Antonin Décimo)
* Prefer SetHandleInformation to DuplicateHandle in set_close_on_exec for sockets. DuplicateHandle mustn't be used on sockets. (#907, Antonin Décimo)
* Lwt.pick and Lwt.choose select preferentially failed promises as per documentation (#856, #874, Raman Varabets)
* Use the WSA_FLAG_NO_HANDLE_INHERIT on Windows when creating sockets with WSASocket if the cloexec (non-inheritable) parameter is true. Fixes a Windows problem where a child process would inherit a supposedly non-inheritable socket. (#910, Antonin Décimo)
* Fix macOS/arm64 tests which have a 16k page. (#932, Kate Deplaix)
* Fix Lwt_unix.closedir incorrectly checking the return value of closedir(3). (#942, Antonin Décimo)
* Fix custom_operations struct not fully initialized after OCaml 4.08. (Antonin Décimo, #918)
* Fix missing include directive. (#940, Antonin Décimo)
* Fix missing initialisation in Unix stub. (#941, Antonin Décimo)
====== Deprecations ======
* Alias Lwt_result.map_err and Lwt_result.bind_lwt_err to Lwt_result.map_error and Lwt_result.bind_lwt_error for consistency with Stdlib. (#927, Antonin Décimo)
===== 5.5.0 =====
====== Deprecations ======
* Lwt_main.yield and Lwt_unix.yield are deprecated in favor of the generic Lwt.pause, and Lwt_unix.auto_yield is deprecated in favor of the new Lwt_unix.auto_pause. Currently, Lwt_main.run resolves paused promises more frequently than yielded promises; the difference is unintended but existing applications could unintentionally depend on it. (#855, #858, Favonia)
====== Fixes ======
* Use is_blocking in dup and dup2 to fix ENOTSOCK on Windows. (#869, Antonin Décimo)
* Lwt_unix.lstat was incorrectly calling Unix.stat on Win32. Fixes the behavior of Lwt_io.with_temp_dir following symlinks to directories on Win32. (#883, Antonin Décimo)
* Support deleting symlinks on Windows during cleanup of Lwt_io.with_temp_dir. (#886, Antonin Décimo)
* Lwt_react.S.l[2-6]_s used polymorphic equality which could cause errors when handling functional values. (#893, Jérôme Vouillon)
* On Windows, treat ERROR_BROKEN_PIPE on read as zero-read instead of error. See OCaml PR #4790. (#898, Antonin Décimo)
* Fix compilation under MSVC by replacing Noreturn with CAMLnoreturn. (#880, #887, Nicolás Ojeda Bär)
====== Additions ======
* Lwt_bytes.blit_from_string: string complement of Lwt_bytes.blit. (#882, Hugo Heuzard)
* Lwt_seq: a Seq-like data-structure with Lwt delayed nodes. (#836, #842, Zach Shipko)
* Lwt_unix.auto_pause: the replacement of Lwt_unix.auto_yield that uses Lwt.pause instead of Lwt_unix.yield. (#855, #858, Favonia)
* Lwt_stream.return, Lwt_stream.return_lwt: singleton stream constructors. (#864, Boning Dong)
* Add ?to_dir param from Unix.symlink to Lwt_unix.symlink wrapper. (#884, Antonin Décimo)
* Lwt_stream.of_lwt_seq to convert an Lwt-sequence into an Lwt-stream. (#873)
* Support IPv6 (always) and PF_UNIX (with OCaml >= 4.14) socketpair on Windows. (#870, #876, Antonin Décimo, David Allsopp)
* In the Lwt_unix module, add `?cloexec:bool` optional arguments to functions that create file descriptors (`dup`, `dup2`, `pipe`, `pipe_in`, `pipe_out`, `socket`, `socketpair`, `accept`, `accept_n`). The `?cloexec` argument is simply forwarded to the wrapped Unix function (with OCaml >= 4.05, see PR ocaml/ocaml#650), or emulated as best-effort with `Unix.set_close_on_exec` on older OCaml versions. (#327, #847, #872, #901, Antonin Décimo)
* Lwt_domain: helpers for using domainslib from Lwt. (#860, Sudha Parimala)
====== Misc ======
* Code quality improvement: remove an unneeded Obj.magic. (#844, Benoit Montagu)
* On Windows, use the Unicode API in C stubs and functions introduced in OCaml 4.06 to handle Unicode strings. Raise the minimum requirement to OCaml 4.06 (on Windows only). (#843, #903, Antonin Décimo)
* More complete coverage in the CI. (#890, #894, #896, Sora Morimoto)
* Code quality improvement: use exception pattern instead of try-with. (#895, Antonin Décimo)
* Code quality improvement: fix warnings on 4.13. (#899)
===== 5.4.2 =====
====== Bugs fixed ======
* Fix compilation on Windows by providing missing dummy stubs (#868, Andreas Hauptmann, Antonin Décimo).
===== 5.4.1 =====
====== Bugs fixed ======
* Fix Lwt_fmt.stderr to actually point to stderr (#852, #850, Volker Diels-Grabsch).
* Make temporary files created by Lwt_io.with_temp_dir deletable on Windows by removing the RO bit (#849, #861, Antonin Décimo).
* Handle ECONNABORTED in Lwt_io.establish_server* (#829, #830, Reynir Björnsson, Hannes Mehnert).
====== Bugfixes ======
* Fix Lwt_fmt.stderr to actually point to stderr (#852, #850, Volker Diels-Grabsch).

* Lwt_main.abandon_yielded_and_paused for use in conjunction with Lwt.fork (#789, Julien Tesson).
* Lwt.wrap_in_cancelable to complete protect and no_cancel (#785).
* Support for IOV_MAX in [Lwt_unix.IO_vectors.system_limit (#801, Pino Toscano).
* Lwt_unix.send_msgto (#805, Antonio Nuno Monteiro).
* Lwt.dont_wait, a more explicit alternative to Lwt.async (#820, François Thiré).
====== Miscellaneous ======
* Avoid double-reversing when traversing lists. This may change the order in which some promises are collected, which may change which of several rejection is arbitrarily selected during concurrent traversal (#784).
* Numerous documentation improvements (including external contributions from Bikal Lem, Sudha Parimala, and Hannes Mehnert).
===== 5.3.0 (2020-04-22) =====

For general discussion of breakage in Lwt 5.0.0, see #584. See #293 about how
Lwt announces and does breaking changes.*
* The signature of Lwt.async will change from (unit -> 'a Lwt.t) -> unit to
(unit -> unit Lwt.t) -> unit (#603, prompted @cfcs).
* Lwt_unix.send_msg and Lwt_unix.recv_msg will be changed to take
Lwt_unix.IO_vectors.t instead of Lwt_unix.io_vectors (#702, prompted
Marcello Seri).
* Nesting calls to Lwt_main.run will be forbidden, and will raise an
Failure. Most programs don't do this (#609, prompted François-René Rideau).
* configure.ml will be removed in favor of an improved discover.ml This
affects only users who are configuring Lwt as part of a manual installation
(i.e., not users of opam or esy). See discover.ml for usage (#700).
* Lwt_unix.async_method will have no effect. In practice, it already does
nothing, and has almost no users (#572).

(#570, reported Tóth Róbert).
===== 4.0.0 (2018-03-30) =====
====== Breaking ======
These changes were announced in Lwt 3.1.0 and Lwt 3.2.0. See #453 about smooth
upgrade paths.

(#338).
* Remove >> syntax from the PPX (#495).
* Delete modules Lwt_log, Lwt_daemon, Lwt_log_core, and package lwt.log. These
are in package lwt_log since Lwt 3.2.0, but it is recommended to use
Logs_lwt from the logs library instead (#484, initiated Hannes Mehnert).
* Delete package lwt.preemptive. It is an alias for lwt.unix since Lwt 3.2.0
(#487).
* Delete package lwt.syntax. The Camlp4 syntax is in package lwt_camlp4 since
Lwt 3.2.0 (#370).

Carty).
* Remove translation of [%lwt ...] to Lwt.catch from the PPX (#527).

* Documentation improvements (#544, #546, #547, #553, #559, Daniil Baturin,
Jason Evans, Jess Smith, Milo Turner).
===== 3.2.1 (2018-01-11) =====
Lwt 3.2.1 is released because it still packages lwt.ppx, a deprecated copy of
package lwt_ppx, and the two packages should be kept in sync.

* All PPX options are deprecated and should not be used (#534).
* The [%lwt ...] PPX syntax should be replaced by Lwt.catch (#534).
====== Fixes ======

* Lwt_pool.wait_queue_length (#493, Jerome Vouillon).
====== Bugs fixed ======
* Lwt.npick never worked (#447, Zack Coker).
* Lwt_pool.use now always calls ?validate on elements (#461, Joe Thomas).
* Better locations generated by the PPX (#470, Fabian Hemmer).
* Keep worker thread count accurate in Lwt_unix when pthread_create fails
(#493, @koen-struyve).
* Leaked exceptions in Lwt_list (#499).

====== Planned to break in 4.0.0 ======
See #453 for details and instructions about planned breakage in Lwt 4.0.0.
* The semantics of Lwt will be adjusted for better exception and stack safety
(#500).
* The PPX will be factored out into its own opam package, lwt_ppx. This
package is installable from opam now, as of Lwt 3.2.0 (#338).
* Similarly, the deprecated Camlp4 syntax will be factored out into
lwt_camlp4, which is installable from opam now (#370).
* Modules Lwt_log, Lwt_log_core, Lwt_log_rules, and Lwt_daemon are being
deprecated and factored out into opam package lwt_log, also installable from
opam now. Use the logs library for logging, in particular module Logs_lwt.
Direct daemonization is deprecated on most platforms (#484, Hannes Mehnert).
* The >> construct from the PPX will be deleted (#471, Raphaël Proust).
* Package lwt.preemptive is being merged into lwt.unix. In 3.2.0,
lwt.preemptive becomes an alias for lwt.unix, and the package name
lwt.preemptive will be deleted in 4.0.0 (#487).
====== Deprecations ======
* Lwt.waiter_of_wakener should not be used, as it can lead to soundness bugs
in future (but not current) Lwt (#458).
* Lwt_sequence was deprecated in Lwt 2.6.0, but it now has a warning attached,
as do Lwt.add_task_r and Lwt.add_task_l, which use it (#361).
* Use of the following functions is discouraged, but they have not yet
received deprecation warnings: Lwt.with_value, Lwt.cancel, Lwt.state,
Lwt.ignore_result (#359, #469).
====== Miscellaneous ======
* Replace references to Camlp4 in the manual with the PPX (#457, Bobby
Priambodo).

some fds (#356, David Sheets).
* Lwt_unix.sleep and Lwt_unix.timeout returning too early when using
libev (#433, Stijn Devriendt).
* Lwt_sequence.fold_r iterating the wrong way in some cases (#405,
Stijn Devriendt).
* Build conflicts in some cases due to duplicate cst_to_constr
function (#362, Jérémie Dimino).
* Don't use deprecated readdir_r system call (#430, Raphaël Proust).
====== Miscellaneous ======

(#354, reviewed Gabriel Radanne, Edwin Török, Raphaël Proust, Jan
Doms, Fabian Hemmer, Sebastien Mondet, Simon Cruanes, Anil
Madhavapeddy, Pierre Chambart, and many others).
* Lots of tests for most of the Lwt core (#339, #389, #392, #440,
#448, #450, Joseph Thomas, Ryan Slade).
* Documentation fixes (including by Joseph Thomas, Raphaël Proust,
Richard Degenne, Stavros Polymenis).
* Contributing documentation (#379).
* Massively adjust whitespace for legibility (#400, #409, #416,
Richard Degenne).

Yotam Barnoy).
* The additional packages lwt_ssl, lwt_react, lwt_glib get new minor
releases, the change being new Jbuilder build systems (#374, Andrew
Ray).
===== 3.0.0 (2017-04-10) =====
====== Breaking ======
* These changes were originally announced in release 2.7.0 (#308).
* Lwt_engine.libev now has an optional argument for selecting the libev back
end (#269, #294, Jeremy Yallop).
* Lwt_io.establish_server has been changed to make it more difficult to leak
file descriptors (#258, #260).
* Lwt_io.shutdown_server now evaluates to a promise, which completes when the
listening socket's close(2) operation completes (#259).
* Lwt_unix.bind now evaluates to a promise, because the bind(2) system call
can block for Unix domain sockets (#296, requested David Sheets).
* ocamlfind packages lwt.react, lwt.ssl, lwt.glib are replaced by lwt_react,
lwt_ssl, lwt_glib. These have been separate OPAM packages, under those
names, since 2.7.0 (#301).

====== General ======
* Values of types a Lwt.t are now referred to as promises rather than threads
(#300). The manual has not yet been updated.
====== Breaking ======

changes will first require deprecation, then a major version number increase
(#293).
* Lwt no longer supports OCaml 4.01 (#272).
* Lwt_unix.fdatasync is no longer available on macOS. It was calling an
undocumented system call on that system (#285, Jeremy Yallop).
====== Planned to break in 3.0.0 ======
* APIs in this category have deprecation messages attached. The messages will
be displayed if you recompile your code, and can also be seen in #308.
* Lwt_engine.libev will have an argument for selecting the libev back end
(#269, #294, Jeremy Yallop).
* Lwt_io.establish_server will be replaced by a version that makes it
difficult to leak file descriptors (#258, #260).
* Lwt_io.shutdown_server will evaluate to a promise, which indicates when the
close operation completes (#259).
* Lwt_unix.bind will evaluate to a promise, since bind can block for Unix
domain sockets (#296, requested David Sheets).
* ocamlfind packages lwt.react, lwt.ssl, and lwt.glib will be replaced by the
new lwt_react, lwt_ssl, and lwt_glib. These are now distributed in new OPAM
packages with the same names, separately from OPAM package lwt (#301).
