I'd like to announce the release of dune 3.5.0 on opam. This release is packed with fixes and new features, that are described below with a description of what this means for project maintainers.
This lists features of the "dune" executable itself. Upgrading dune will bring in these changes. We consider these changes safe, but it is difficult to define what a breaking change is for a command-line tool (for example, some error messages change). It is important to note that just upgrading the dune executable is not supposed to change how dune interprets existing projects. If just upgrading dune breaks compilation, it is a bug in dune, please report it!

#6169, @shonfeder)This is technically a subset of above section. For M1 mac users, dune 3.5.0 is the first version which will correctly support dune-build-info.
This lists changes if you opt into the new (lang dune 3.5) version in your dune-project file. For this too, these are changes that we consider safe, but they can require changes to your dune files. For example, sandboxing is enabled in more places, which means that you might have to be more precise in expressing your dependencies. Please reach out on the issue tracker if you have trouble fixing your dune file or if something does not seem to be possible anymore.

We are pleased to announce the minor release of opam 2.1.3.
This opam release consists of backported fixes:
opam init and opam init --reinit when the jobs variable has been set in the opamrc or the current config. (#5056)opam var no longer fails if no switch is set (#5025)--switch <sw> fails instead of writing an invalid switch-config file (#5027)opam pin (#5046)and improvements:
opam list --installable queries combined with other filters (#4311)--available, --installable) (#4999)opam list --conflicts-with when combined with other filters (#4999)opam show by as much as 300% when the package to show is given explicitly or is unique (#4997)(#4172)You can also find API changes in the release note.
Opam installation instructions (unchanged):
From binaries: run
bash -c "sh <(curl -fsSL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh) --version 2.1.3"
or download manually from the Github "Releases" page to your PATH. In this case, don't forget to run opam init --reinit -ni to enable sandboxing if you had version 2.0.0~rc manually installed or to update you sandbox script.
From source, using opam:
opam update; opam install opam-devel
(then copy the opam binary to your PATH as explained, and don't forget to run opam init --reinit -ni to enable sandboxing if you had version 2.0.0~rc manually installed or to update your sandbox script)
From source, manually: see the instructions in the README.
We hope you enjoy this new minor version, and remain open to bug reports and suggestions.

Bug fixes, a couple new features, better hints and error messages - I won't restate what's in the changelog below. Thanks to everyone involved in this release!
Make dune describe correctly handle overlapping implementations
for virtual libraries (#5971, fixes #5747, @esope)
Building the @check alias should make sure the libraries and executables
don't have dependency cycles (#5892, @rgrinberg)
[ctypes] Add support for the errno parameter using the errno_policy field
in the ctypes settings. (#5827, @droyo)
Fix dune coq top when it is invoked on files from a subdirectory of the
directory containing the associated stanza (#5784, fixes #5552, @ejgallego,
@rlepigre, @Alizter)
Fix hint when an invalid module name is found. (#5922, fixes #5273, @emillon)
The (cat) action now supports several files. (#5928, fixes #5795, @emillon)
Dune no longer uses shimmed META files for OCaml 5.x, solely using the ones
installed by the compiler. (#5916, @dra27)
Fix handling of the (deps) field in (test) stanzas when there is an
.expected file. (#5952, #5951, fixes #5950, @emillon)
Ignore insignificant filesystem events. This stops RPC in watch mode from
flashing errors on insignificant file system events such as changes in the
.git/ directory. (#5953, @rgrinberg)
Fix parsing more error messages emitted by the OCaml compiler. In particular, messages where the excerpt line number started with a blank character were skipped. (#5981, @rgrinberg)
env stanza: warn if some rules are ignored because they appear after a wildcard rule. (#5898, fixes #5886, @emillon)
On Windows, XDG_CACHE_HOME is taken to be the FOLDERID_InternetCache if
unset, and XDG_CONFIG_HOME and XDG_DATA_HOME are both taken to be
FOLDERID_LocalAppData if unset. (#5943, fixes #5808, @nojb)

Add --fallback-read-dot-merlin to the LSP Server (#705). If ocamllsp is
started with this new flag, it will fall back to looking for Merlin
configuration in .merlin files rather than calling dune ocaml-merlin.
(#705)
Support folding more ranges (#692)
Improve parsing of ocamlc errors. We now correctly strip excerpts and parse alerts (#5879, @rgrinberg)
The (libraries) field of the coq.theory stanza has been renamed to
(plugins) and the Coq language version has been bumped to 0.5.
On behalf of the dune team, I’m pleased to announce the release of version 3.3.0. This is the first version that supports the upcoming OCaml 5.0. It also improves safety by sandboxing more rules and enabling more warnings, and there's a bunch of new features on the coq side too. Full changelog follows.
Note that as usual, dune works hard not to break existing packages. So even if it mentions that rules require precise dependencies, for example, this new safety net is only enabled for project that use (lang dune 3.3).
Happy hacking.
Sandbox preprocessing, lint, and dialect rules by default. All these rules now require precise dependency specifications (#5807, @rgrinberg)
Allow list expansion in the pps specification for preprocessing (#5820,
@Firobe)
Add warnings 67-69 to dune's default set of warnings. These are warnings of the form "unused X.." (#5844, @rgrinberg)
Introduce project "composition" for coq theories. Coq theories in separate projects can now refer to each other when in the same workspace (#5784, @Alizter, @rgrinberg)
Fix hint message for data_only_dirs that wrongly mentions the unknown
constructor data_only (#5803, @lambdaxdotx)
Fix creating sandbox directory trees by getting rid of buggy memoization (#5794, @rgrinberg, @snowleopard)
Handle directory dependencies in sandboxed rules. Previously, the parents of these directory dependencies weren't created. (#5754, @rgrinberg)
Set the exit code to 130 when dune is terminated with a signal (#5769, fixes #5757)
Support new locations of unix, str, dynlink in OCaml >= 5.0 (#5582, @dra27)
The coq.theory stanza now produces rules for running coqdoc. Given a
theory named mytheory, the directory targets mytheory.html/ and
mytheory.tex/ or additionally the aliases @doc and @doc-latex will
build the HTML and LaTeX documentation repsectively. (#5695, fixes #3760,
@Alizter)
Coq theories marked as (boot) cannot depend on other theories
(#5867, @ejgallego)
Ignore bigarray in (libraries) with OCaml >= 5.0. (#5526, fixes #5494,
@moyodiallo)
Start with :standard when building the ctypes generated foreign stubs so that we include important compiler flags, such as -fPIC (#5816, fixes #5809).
compact and sparse are now removed (#2075, @gpetiot)align-cases, align-constructors-decl and align-variants-decl are now removed (#2076, @gpetiot)disable-outside-detected-project is now removed (#2077, @gpetiot)$XDG_CONFIG_HOME or $HOME/.config) is only applied when no project is detected, --enable-outside-detected-project is set, and no applicable .ocamlformat file has been found. Global and local configurations are no longer used at the same time. (#2039, @gpetiot)ocaml-version to a fixed version (4.04.0) by default to avoid reproducibility issues and surprising behaviours (#2064, @kit-ty-kate)--numeric=X-Y into --range=X-Y and --numeric (flag). For now --range can only be used with --numeric. (#2073, #2082, @gpetiot)(*= ... *) for verbatim comments (#2028, @gpetiot)--print-config displays a warning when an .ocamlformat file defines redundant options (already defined by a profile) (#2084, @gpetiot)dune-project. The parser could get confused
when opam file generation is used. Now it only considers the first (name X)
in the file. (#445, #446, @emillon)On behalf of the dune team, I'm pleased to announce the availability of version 3.2.0. This release contains few new features, but is packed with bug fixes and usability improvements. In particular, I'd like to point out that we've continued to improve the user experience with the watch mode. I encourage you all to try it out if you haven't already.
Happy Hacking.

handles Reason files, as well as files any other dialect. (#5701, @esope)
Disable alerts when compiling code in vendored directories (#5683, @NathanReb)
Fixed dune describe --with-deps, that crashed when some
preprocessing was required in a dune file using per_module.

The output of jobs that finished but were cancelled is now omitted. (#5631, fixes #5482, @rgrinberg)
Allows to configure all the default destination directories with ./configure
(adds bin, sbin, data, libexec). Use OPAM_SWITCH_PREFIX instead of
calling the opam binaries in dune install. Fix handling of multiple
libdir in ./configure for handling /usr/lib/ocaml/ and
/usr/local/lib/ocaml. In dune install forbid relative directories in
libdir, docdir and others specific directory setting because their handling
was inconsistent (#5516, fixes #3978 and #5455, @bobot)

on some terminals (#5646, @rgrinberg)
Add a fmt command as a shortcut of dune build @fmt --auto-promote (#5574,

wild before findlib documented plugin(native|byte) in 2015 (#5518, @bobot)
Fix a bug where Dune would not correctly interpret META files in alternative
layout (ie when the META file is named META.$pkg). The Llvm bindings were
affected by this issue. (#5619, fixes #5616, @nojb)
Support (binaries) in (env) in dune-workspace files (#5560, fix #5555,
