2.1.2 (08/01/2020)

Fix a bug in the Fiber.finalize function of the concurrency monad of Dune, causing a race condition at the user level (#3009, fix #2958, @diml)

2.1.1 (07/01/2020)

Guess foreign archives & native archives for libraries defined using the META format. (#2994, @rgrinberg, @anmonteiro)

2.1.0 (21/12/2019)

Attach cinaps stanza actions to both @runtest and @cinaps aliases (#2831, @NathanReb)
Add variables %{lib-private...} and %{libexec-private...} for finding build paths of files in public and private libraries within the same project. (#2901, @snowleopard)
Add --mandir option to $ dune install. This option allows to override the installation directory for man pages. (#2915, fixes #2670, @rgrinberg)
Fix dune --version. The bootstrap didn't compute the version correctly. (#2929, fixes #2911, @diml)
Do not open the log file in dune clean. (#2965, fixes #2964 and #2921, @diml)
Support passing two arguments to =, <>, ... operators in package dependencies so that we can have things such as (<> :os win32) (#2965, @diml)

2.0.1 (17/12/2019)

Delay errors raised by invalid dune-package files. The error is now raised only if the invalid package is treated as a library and used to build something. (#2972, @rgrinberg)

2.0.0 (20/11/2019)

Remove existing destination files in install before installing the new ones. (#2885, fixes #2883, @bschommer)
The action field in the alias stanza is not available starting lang dune 2.0. The alias field in the rule stanza is a replacement. (#2846, fixes 2681, @rgrinberg)
Introduce alias and package fields to the rule stanza. This is the preferred way of attaching rules to aliases. (#2744, @rgrinberg)
Add field (optional) for executable stanzas (#2463, fixes #2433, @bobot)
Infer targets for rule stanzas expressed in long form (#2494, fixes #2469, @NathanReb)
Indicate the progress of the initial file tree loading (#2459, fixes #2374, @bobot)
Build .cm[ox] files for executables more eagerly. This speeds up builds at the cost of building unnecessary artifacts in some cases. Some of these extra artifacts can fail to built, so this is a breaking change. (#2268, @rgrinberg)
Do not put the <package>.install files in the source tree unless -p or --promote-install-files is passed on the command line (#2329, @diml)
Compilation units of user defined executables are now mangled by default. This is done to prevent the accidental collision with library dependencies of the executable. (#2364, fixes #2292, @rgrinberg)
Enable (explicit_js_mode) by default. (#1941, @nojb)
Add an option to clear the console in-between builds with --terminal-persistence=clear-on-rebuild
Stop symlinking object files to main directory for stanzas defined jbuild files (#2440, @rgrinberg)
Library names are now validated in a strict fashion. Previously, invalid names would be allowed for unwrapped libraries (#2442, @rgrinberg)
mli only modules must now be explicitly declared. This was previously a warning and is now an error. (#2442, @rgrinberg)
Modules filtered out from the module list via the Ordered Set Language must now be actual modules. (#2442, @rgrinberg)
Actions which introduce targets where new targets are forbidden (e.g. preprocessing) are now an error instead of a warning. (#2442, @rgrinberg)
No longer install a jbuilder binary. (#2441, @diml)
Stub names are no longer allowed relative paths. This was previously a warning and is now an error (#2443, @rgrinberg).
Define (paths ...) fields in (context ...) definitions in order to set or extend any PATH-like variable in the context environment. (#2426, @nojb)
The diff action will always normalize newlines before diffing. Perviousy, it would not do this normalization for rules defined in jbuild files. (#2457, @rgrinberg)
Modules may no longer belong to more than one stanza. This was previously allowed only in stanzas defined in jbuild files. (#2458, @rgrinberg)
Remove support for jbuild-ignore files. They have been replaced by the the dirs stanza in dune files. (#2456, @rgrinberg)
Add a new config option sandboxing_preference, the cli argument --sandbox, and the dep spec sandbox in dune language. These let the user control the level of sandboxing done by dune per rule and globally. The rule specification takes precedence. The global configuration merely specifies the default. (#2213, @aalekseyev, @diml)
Remove support for old style subsystems. Dune will now emit a warning to reinstall the library with the old style subsystem. (#2480, @rgrinberg)
Add action (with-stdin-from ) to redirect input from when performing . (#2487, @nojb)
Change the automatically generated odoc index to only list public modules. This only affects unwrapped libraries (#2479, @rgrinberg)

Change default target from @install to @all. (#2449, fixes #1220, @rgrinberg)
Include building stubs in @check rules. (@rgrinberg, #2530)
Get rid of ad-hoc rules for guessing the version. Dune now only relies on the version written in the dune-project file and no longer read VERSION or similar files (#2541, @diml)
In (diff? x y) action, require x to exist and register a dependency on that file. (#2486, @aalekseyev)
On Windows, an .exe suffix is no longer added implicitly to binary names that already end in .exe. Second, when resolving binary names, .opt variants are no longer chosen automatically. (#2543, @nojb)
Make (diff? x y) move the correction file (y) away from the build directory to promotion staging area. This makes corrections work with sandboxing and in general reduces build directory pollution. (#2486, @aalekseyev, fixes #2482)
c_flags, c_names and cxx_names are now supported in executable and executables stanzas. (#2562, @nojb) Note: this feature has been subsequently extended into a separate foreign_stubs field. (#2659, RFC #2650, @snowleopard)
Remove git integration from $ dune upgrade (#2565, @rgrinberg)
Add a --disable-promotion to disable all modification to the source directory. There's also a corresponding DUNE_DISABLE_PROMOTION environment variable. (#2588, fix #2568, @rgrinberg)
Add a forbidden_libraries field to prevent some library from being linked in an executable. This help detecting who accidently pulls in unix for instance (#2570, @diml)
Fix incorrect error message when a variable is expanded in static context: %{lib:lib:..} when the library does not exist. (#2597, fix #1541, @rgrinberg)
Add --sections option to $ dune install to install subsections of .install files. This is useful for installing only the binaries in a workspace for example. (#2609, fixes #2554, @rgrinberg)
Drop support for jbuild and jbuild-ignore files (#2607, @diml)
Add a dune-action-plugin library for describing dependencies direcly in the executable source. Programs that use this feature can be run by a new action (dynamic-run ...). (#2635, @staronj, @aalekseyev)
Stop installing the ocaml-syntax-shims binary. In order to use future_syntax, one now need to depend on the ocaml-syntax-shims package (#2654, @diml)
Add support for dependencies that are re-exported. Such dependencies are marked withre_export and will automatically be provided to users of a library (#2605, @rgrinberg)
Add a deprecated_library_name stanza to redirect old names after a library has been renamed (#2528, @diml)
Error out when a preprocessor_deps field is present but not preprocess field is. It is a warning with Dune 1.x projects (#2660, @Julow)
Dune will use -output-complete-exe instead of -custom when compiling self-contained bytecode executables whenever this options is available (OCaml version >= 4.10) (#2692, @nojb)
Add action (with-accepted-exit-codes <pred> <action>) to specify the set of successful exit codes of <action>. <pred> is specified using the predicate language. (#2699, @nojb)
Do not setup rules for disabled libraries (#2491, fixes #2272, @bobot)
Configurator: filter out empty flags from pkg-config (#2716, @AltGr)
no_keep_locs is a no-op for projects that use lang dune older than 2.0. In projects where the language is at least 2.0, the field is now forbidden. (#2752, fixes #2747, @rgrinberg)
Extend support for foreign sources and archives via the (foreign_library ...) stanza as well as the (foreign_stubs ...) and (foreign_archives ...) fields. (#2659, RFC #2650, @snowleopard)
Add (deprecated_package_names) field to (package) declaration in dune-project. The names declared here can be used in the (old_public_name) field of (deprecated_library_name) stanza. These names are interpreted as library names (not prefixed by a package name) and appropiate redirections are setup in their META files. This feaure is meant to migrate old libraries which do not follow Dune's convention of prefixing libraries with the package name. (#2696, @nojb)
The fields license, authors, maintainers, source, bug_reports, homepage, and documentation of dune-project can now be overriden on a per-package basis. (#2774, @nojb)
Change the default modes field of executables to (mode exe). If one wants to build a bytecode program, it now needs to be explicitly requested via (modes byte exe). (#2851, @diml)
Allow ccomp_type as a variable for evaluating enabled_if. (#2855, @dra27, @rgrinberg)
Stricter validation of file names in select. The file names of conditional sources must match the prefix and the extension of the resultant filename. (#2867, @rgrinberg)
Add flag disable_dynamically_linked_foreign_archives to the workspace file. If the flag is set to true then: (i) when installing libraries, we do not install dynamic foreign archives dll*.so; (ii) when building executables in the byte mode, we statically link in foreign archives into the runtime system; (iii) we do not generate any dll*.so rules. (#2864, @snowleopard)
Reimplement the bootstrap procedure. The new procedure is faster and should no longer stack overflow (#2854, @dra27, @diml)
Allow .opam.template files to be generated using rules (#2866, @rgrinberg)

1.11.2 (20/08/2019)

Remove the optimisation of passing -nodynlink for executalbes when not necessary. It seems to be breaking things (see #2527, @diml)

Check that selected implementations (either by variants or default implementations) are indeed implementations. (#2328, @TheLortex, review by @rgrinberg)
Don't reserve the Ppx toplevel module name for ppx rewriters (#2242, @diml)
Redesign of the library variant feature according to the #2134 proposal. The set of variants is now computed when the virtual library is installed. Introducing a new external_variant stanza. (#2169, fixes #2134, @TheLortex, review by @diml)
Add proper line directives when copying .cc and .cxx sources (#2275, @rgrinberg)
Fix error message for missing C++ sources. The .cc extension was always ignored before. (#2275, @rgrinberg)

Allow to embed build info in executables such as version and list and version of statically linked libraries (#2224, @diml)
Set version in META and dune-package files to the one read from the vcs when no other version is available (#2224, @diml)
Add a variable %{target} to be used in situations where the context requires at most one word, so %{targets} can be confusing; stdout redirections and "-o" arguments of various tools are the main use case; also, introduce a separate field target that must be used instead of targets in those situations. (#2341, @aalekseyev)
Fix dependency graph of wrapped_compat modules. Previously, the dependency on the user written entry module was omitted. (#2305, @rgrinberg)
Allow to promote executables built with an executable stanza (#2379, @diml)
When instantiating an implementation with a variant, make sure it matches virtual library's list of known implementations. (#2361, fixes #2322, @TheLortex, review by @rgrinberg)

Fix a bug in future_syntax where the characters @ and & were not distinguished in the names of binding operators (let@ was the same as let&) (#2376, @aalekseyev, @diml)
Workspaces with non unique project names are now supported. (#2377, fix #2325, @rgrinberg)
Improve opam generation to include the dune dependencies with the minimum constraint set based on the dune language version specified in the dune-project file. (2383, @avsm)
The order of fields in the generated opam file now follows order preferred in opam-lib. (@avsm, #2380)

Add (dialect ...) stanza (@nojb, #2404)
Add a --context argument to dune install/uninstall (@diml, #2412)
Do not warn about merlin files pre 1.9. This warning can only be disabled in 1.9 (#2421, fixes #2399, @emillon)
Add a new inline_tests field in the env stanza to control inline_tests framework with a variable (#2313, @mlasson, original idea by @diml, review by @rgrinberg).
New binary kind js for executables in order to explicitly enable Javascript targets, and a switch (explicit_js_mode) to require this mode in order to declare JS targets corresponding to executables. (#1941, @nojb)

1.10.0 (04/06/2019)

Restricted the set of variables available for expansion in the destination filename of install stanza to simplify implementation and avoid dependency cycles. (#2073, @aalekseyev, @diml)

[coq] Add coq.pp stanza to help with pre-processing of grammar files (#2054, @ejgallego, review by @rgrinberg)
Add a new more generic form for the promote mode: (promote (until-clean) (into <dir>)) (#2068, @diml)
Allow to promote only a subset of the targets via (promote (only <pred>)). For instance: (promote (only *.mli)) (#2068, @diml)
Improve the behavior when a strict subset of the targets of a rule is already in the source tree for projects using the dune language < 1.10 (#2068, fixes #2061, @diml)
With lang dune >= 1.10, rules in standard mode are no longer allowed to produce targets that are present in the source tree. This has been a warning for long enough (#2068, @diml)
Allow %{...} variables in pps flags (#2076, @mlasson review by @diml and @aalekseyev).
Add a 'cookies' option to ppx_rewriter/deriver flags in library stanzas. This allow to specify cookie requests from variables expanded at each invocation of the preprocessor. (#2106, @mlasson @diml)
Add more opam metadata and use it to generate .opam files. In particular, a package field has been added to specify package specific information. (#2017, #2091, @avsm, @jonludlam, @rgrinberg)
Clean up the special support for findlib.dynload. Before, Dune would simply match on the library name. Now, we only match on the findlib package name when the library doesn't come from Dune. Someone writing a library called findlib.dynload with Dune would have to add (special_builtin_support findlib_dynload) to trigger the special behavior. (#2115, @diml)
Install the future_syntax preprocessor as ocaml-syntax-shims.exe (#2125, @rgrinberg)
Hide full command on errors and warnings in development and show them in CI. (detected using the CI environment variable). Commands for which the invocation might be omitted must output an error prefixed with File . Add an --always-show-command-line option to disable this behavior and always show the full command. (#2120, fixes #1733, @rgrinberg)
In dune-workspace files, add the ability to choose the host context and to create duplicates of the default context with different settings. (#2098, @TheLortex, review by @diml, @rgrinberg and @aalekseyev)
Add support for hg in dune subst (#2135, @diml)

Make dune subst add a (version ...) field to the dune-project file (#2148, @diml)
Add the %{os_type} variable, which is a short-hand for %{ocaml-config:os_type} (#1764, @diml)
Allow enabled_if fields in library stanzas, restricted to the %{os_type}, %{model}, %{architecture}, %{system} variables (#1764, #2164 @diml, @rgrinberg)
Fix chdir on external and source paths. Dune will also fail gracefully if the external or source path does not exist (#2165, fixes #2158, @rgrinberg)
Support the .cc extension fro C++ sources (#2195, fixes #83, @rgrinberg)
Run ocamlformat relative to the context root. This improves the locations of errors. (#2196, fixes #1370, @rgrinberg)
Fix detection of README, LICENSE, CHANGE, and HISTORY files. These would be undetected whenever the project was nested in another workspace. (#2194, @rgrinberg)
Fix generation of .merlin whenever there's more than one stanza with the same ppx preprocessing specification (#2209 ,fixes #2206, @rgrinberg)
Fix generation of .merlin in the presence of the copy_files stanza and preprocessing specifications of other stanazs. (#2211, fixes #2206, @rgrinberg)
Run refmt from the context's root directory. This improves error messages in case of syntax errors. (#2223, @rgrinberg)
In .merlin files, don't pass -dump-ast to the future_syntax preprocessor. Merlin doesn't seem to like it when binary AST is generated by a -pp preprocessor. (#2236, @aalekseyev)
dune install will verify that all files mentioned in all .install files exist before trying to install anything. This prevents partial installation of packages (#2230, @rgrinberg)

1.9.3 (06/05/2019)

Fix .install files not being generated (#2124, fixes #2123, @rgrinberg)

1.9.2 (02/05/2019)

Put back library variants in development mode. We discovered a serious unexpected issue and we might need to adjust the design of this feature before we are ready to commit to a final version. Users will need to write (using library_variants 0.1) in their dune-project file if they want to use it before the design is finalized. (#2116, @diml)
Forbid to attach a variant to a library that implements a virtual library outside the current project (#2104, @rgrinberg)
Fix a bug where dune install would install man pages to incorrect paths when compared to opam-installer. For example dune now installs (foo.1 as man1/foo.1) correctly and previously that was installed to man1/man1/foo.1. (#2105, @aalekseyev)
Do not fail when a findlib directory doesn't exist (#2101, fix #2099, @diml)

Fix crash when calculating library dependency closure (#2090, fixes #2085, @rgrinberg)
Clean up the special support for findlib.dynload. Before, Dune would simply match on the library name. Now, we only match on the findlib package name when the library doesn't come from Dune. Someone writing a library called findlib.dynload with Dune would have to add (special_builton_support findlib_dynload) to trigger the special behavior. (#2115, @diml)
Include permissions in the digest of targets and dependencies (#2121, fix #1426, @rgrinberg, @xclerc)

1.9.1 (11/04/2019)

Do not crash if unable to read a directory when traversing to find root (#2024, @rgrinberg)
Do not exit dune if some source directories are unreadable. Instead, warn the user that such directories need to be ignored (#2004, fix #310, @rgrinberg)
Fix nested (binaries ..) fields in the env stanza. Previously, parent binaries fields would be ignored, but instead they should be combined. (#2029, @rgrinberg)
Allow "." in c_names and cxx_names (#2036, fix #2033, @rgrinberg)
Format rules: if a dune file uses OCaml syntax, do not format it. (#2014, fix #2012, @emillon)

1.8.2 (10/03/2019)

Fix auto-generated index.mld. Use correct headings for the listing. (#1925, @rgrinberg, @aantron)

Add c_flags and cxx_flags to env profile settings (#1700 and #1800, @gretay-js)
Format dune printenv output (#1867, fix #1862, @emillon)
Add the (promote-into <dir>) and `(promote-until-clean-into

Configurator: Fix misquoting when running pkg-config (#1835, fix #1833, @Chris00)

1.7.0 (12/02/2019)

Second step of the deprecation of jbuilder: the jbuilder binary now emits a warning on every startup and both jbuilder and dune emit warnings when encountering jbuild files (#1752, @diml)

Don't pass -runtime-variant _pic on Windows (#635, fixes #573 @diml)
Display documentation in alphabetical order. This is relevant to packages, libraries, and modules. (#647, fixes #606 @rgrinberg)

Use the host's PATH variable when running actions during cross compilation (#649, fixes #625 @rgrinberg)
Fix incorrect include (-I) flags being passed to odoc. These flags should be directories that include .odoc files, rather than the include flags of the libraries. (#652 fixes #651 @rgrinberg)
Fix a regression introduced by beta19 where the generated merlin files didn't include the right -ppx flags in some cases (#658 fixes #657 @diml)

Now even if there is no link time conflict, we don't allow an external dependency to overlap with a local library, unless the user specifies allow_overlapping_dependencies in the jbuild file (#587, fixes #562)
Expose a few more variables in jbuild files: ext_obj, ext_asm, ext_lib, ext_dll and ext_exe as well as ${ocaml-config:XXX} for most variables in the output of ocamlc -config (#590)

Fix generation of the implicit alias module with 4.02. With 4.02 it must have an implementation while with OCaml >= 4.03 it can be an interface only module (#549)
Let the parser distinguish quoted strings from atoms. This makes possible to use "${v}" to concatenate the list of values provided by a split-variable. Concatenating split-variables with text is also now required to be quoted.
Split calls to ocamldep. Before ocamldep would be called once per library/executables stanza. Now it is called once per file (#486)
Make sure to not pass -I <stdlib-dir> to the compiler. It is useless and it causes problems in some cases (#488)

Store artifacts for libraries and executables in separate directories. This ensure that Two libraries defined in the same directory can't see each other unless one of them depend on the other (#472)
Better support for mli/rei only modules (#489)
Fix support for byte-code only architectures (#510, fixes #330)
Fix a regression in external-lib-deps introduced in 1.0+beta17 (#512, fixes #485)
@doc alias will now build only documentation for public libraries. A new @doc-private alias has been added to build documentation for private libraries.
Refactor internal library management. It should now be possible to run jbuilder build @lint in Base for instance (#516)
Fix invalid warning about non-existent directory (#536, fixes #534)

1.0+beta17 (01/02/2018)

Make jbuilder aware that num is an external package in OCaml >= 4.06.0 (#358)
jbuilder exec will now rebuild the executable before running it if necessary. This can be turned off by passing --no-build (#345)
Fix jbuilder utop to work in any working directory (#339)
Fix generation of META synopsis that contains double quotes (#337)
Add S . to .merlin by default (#284)
Improve jbuilder exec to make it possible to execute non public executables. jbuilder exec path/bin will execute bin inside default (or specified) context relative to path. jbuilder exec /path will execute /path as absolute path but with the context's environment set appropriately. Lastly, jbuilder exec will change the root as to which paths are relative using the -root option. (#286)
Fix jbuilder rules printing rules when some binaries are missing (#292)
Build documentation for non public libraries (#306)
Fix doc generation when several private libraries have the same name (#369)
Fix copy# for C/C++ with Microsoft C compiler (#353)
Add support for cross-compilation. Currently we are supporting the opam-cross-x repositories such as opam-cross-windows (#355)
Simplify generated META files: do not generate the transitive closure of dependencies in META files (#405)
Deprecated ${!...}: the split behavior is now a property of the variable. For instance ${CC}, ${^}, ${read-lines:...} all expand to lists unless used in the middle of a longer atom (#336)
Add an (include ...) stanza allowing one to include another non-generated jbuild file in the current file (#402)
Add a (diff <file1> <file2>) action allowing to diff files and promote generated files in case of mismatch (#402, #421)
Add jbuilder promote and --auto-promote to promote files (#402, #421)
Report better errors when using (glob_files ...) with a directory that doesn't exist (#413, Fix #412)
Jbuilder now properly handles correction files produced by ppx_driver. This allows to use [@@deriving_inline] in .ml/.mli files. This require ppx_driver >= v0.10.2 to work properly (#415)
Make jbuilder load rules lazily instead of generating them all eagerly. This speeds up the initial startup time of jbuilder on big workspaces (#370)
Now longer generate a META.pkg.from-jbuilder file. Now the only way to customize the generated META file is through META.pkg.template. This feature was unused and was making the code complicated (#370)
Remove read-only attribute on Windows before unlink (#247)
Use /Fo instead of -o when invoking the Microsoft C compiler to eliminate deprecation warning when compiling C++ sources (#354)
Add a mode field to rule stanzas:
- (mode standard) is the default
- (mode fallback) replaces (fallback)
- (mode promote) means that targets are copied to the source tree after the rule has completed
- (mode promote-until-clean) is the same as (mode promote) except that jbuilder clean deletes the files copied to the source tree. (#437)
Add a flag --ignore-promoted-rules to make jbuilder ignore rules with (mode promote). -p implies --ignore-promoted-rules (#437)
Display a warning for invalid lines in jbuild-ignore (#389)
Always build boot.exe as a bytecode program. It makes the build of jbuilder faster and fix the build on some architectures (#463, fixes #446)
Fix bad interaction between promotion and incremental builds on OSX (#460, fix #456)
Make the beginning of a new build more explicit in watch mode (#2542 @diml)

1.0+beta16 (05/11/2017)

Fix build on 32-bit OCaml (#313)

1.0+beta15 (04/11/2017)

Change the semantic of aliases: there are no longer aliases that are recursive such as install or runtest. All aliases are non-recursive. However, when requesting an alias from the command line, this request the construction of the alias in the specified directory and all its children recursively. This allows users to get the same behavior as previous recursive aliases for their own aliases, such as example. Inside jbuild files, one can use (deps (... (alias_rec xxx) ...)) to get the same behavior as on the command line. (#268)
Include sub libraries that have a . in the generated documentation index (#280).
Fix "up" links to the top-level index in the odoc generated documentation (#282).
Fix ARCH_SIXTYFOUR detection for OCaml 4.06.0 (#303)

1.0+beta14 (11/10/2017)

Add (copy_files ) and (copy_files# ) stanzas. These stanzas setup rules for copying files from a sub-directory to the current directory. This provides a reasonable way to support multi-directory library/executables in jbuilder (#35, @bobot)
An empty jbuild-workspace file is now interpreted the same as one containing just (context default)
Better support for on-demand utop toplevels on Windows and when the library has C stubs
Print Entering directory '...' when the workspace root is not the current directory. This allows Emacs and Vim to know where relative filenames should be interpreted from. Fixes #138
Fix a bug related to menhir stanzas: menhir stanzas with a merge_into field that were in jbuild files in sub-directories where incorrectly interpreted (#264)
Add support for locks in actions, for tests that can't be run concurrently (#263)
Support ${..} syntax in the include stanza. (#231)

1.0+beta13 (05/09/2017)

Generate toplevel html index for documentation (#224, @samoht)
Fix recompilation of native artifacts. Regression introduced in the last version (1.0+beta12) when digests replaces timestamps for checking staleness (#238, @dra27)

1.0+beta12 (18/08/2017)

Fix the quoting of FLG lines in generated .merlin files (#200, @mseri)
Use the full path of archive files when linking. Before jbuilder would do: -I <path> file.cmxa, now it does -I <path> <path>/file.cmxa. Fixes #118 and #177
Use an absolute path for ppx drivers in .merlin files. Merlin <3.0.0 used to run ppx commands from the directory where the .merlin was present but this is no longer the case
Allow to use jbuilder install in contexts other than opam; if ocamlfind is present in the PATH and the user didn't pass --prefix or --libdir explicitly, use the output of ocamlfind printconf destdir as destination directory for library files (#179, @bobot)
Allow (:include ...) forms in all *flags fields (#153, @dra27)
Add a utop subcommand. Running jbuilder utop in a directory builds and executes a custom utop toplevel with all libraries defined in the current directory (#183, @rgrinberg)
Do not accept per_file anymore in preprocess field. per_file was renamed per_module and it is planned to reuse per_file for another purpose
Warn when a file is both present in the source tree and generated by a rule. Before, jbuilder would silently ignore the rule. One now has to add a field (fallback) to custom rules to keep the current behavior (#218)
Get rid of the deprecated-ppx-method findlib package for ppx rewriters (#222, fixes #163)
Use digests (MD5) of files contents to detect changes rather than just looking at the timestamps. We still use timestamps to avoid recomputing digests. The performance difference is negligible and we avoid more useless recompilations, especially when switching branches for instance (#209, fixes #158)

1.0+beta11 (21/07/2017)

Fix the error message when there are more than one <package>.opam file for a given package
Report an error when in a wrapped library, a module that is not the toplevel module depends on the toplevel module. This doesn't make as such a module would in theory be inaccessible from the outside
Add ${SCOPE_ROOT} pointing to the root of the current scope, to fix some misuses of ${ROOT}
Fix useless hint when all missing dependencies are optional (#137)
Fix a bug preventing one from generating META.pkg.template with a custom rule (#190)
Fix compilation of reason projects: .rei files where ignored and caused the build to fail (#184)

1.0+beta10 (08/06/2017)

Add a clean subcommand (@rdavison, #89)
Add support for generating API documentation with odoc (#74)
Don't use unix in the bootstrap script, to avoid surprises with Cygwin
Improve the behavior of jbuilder exec on Windows
Add a --no-buffer option to see the output of commands in real-time. Should only be used with -j1
Deprecate per_file in preprocessing specifications and rename it per_module
Deprecate copy-and-add-line-directive and rename it copy#
Remove the ability to load arbitrary libraries in jbuild file in OCaml syntax. Only unix is supported since a few released packages are using it. The OCaml syntax might eventually be replaced by a simpler mechanism that plays better with incremental builds
Properly define and implement scopes
Inside user actions, ${^} now includes files matches by (glob_files ...) or (file_recursively_in ...)
When the dependencies and targets of a rule can be inferred automatically, you no longer need to write them: (rule (copy a b))
Inside (run ...), ${xxx} forms that expands to lists can now be split across multiple arguments by adding a !: ${!xxx}. For instance: (run foo ${!^})
Add support for using the contents of a file inside an action:
- ${read:<file>}
- ${read-lines:<file>}
- ${read-strings:<file>} (same as read-lines but lines are escaped using OCaml convention)
When exiting prematurely because of a failure, if there are other background processes running and they fail, print these failures
With msvc, -lfoo is transparently replaced by foo.lib (@dra27, #127)
Automatically add the .exe when installing executables on Windows (#123)
(run <prog> ...) now resolves <prog> locally if possible. i.e. (run ${bin:prog} ...) and (run prog ...) behave the same. This seems like the right default
Fix a bug where jbuild rules would crash instead of reporting a proper build error
Fix a race condition in future.ml causing jbuilder to crash on Windows in some cases (#101)
Fix a bug causing ppx rewriter to not work properly when using multiple build contexts (#100)
Fix .merlin generation: projects in the same workspace are added to merlin's source path, so "locate" works on them.

1.0+beta9 (19/05/2017)

Add support for building Reason projects (@rgrinberg, #58)
Add support for building javascript with js-of-ocaml (@hhugo, #60)
Better support for topkg release workflow. See topkg-jbuilder for more details
Port the manual to rst and setup a jbuilder project on readthedocs.org (@rgrinberg, #78)
Hint for mistyped targets. Only suggest correction on the basename for now, otherwise it's slow when the workspace is big
Add a (package ...) field for aliases, so that one can restrict tests to a specific package (@rgrinberg, #64)
Fix a couple of bugs on Windows:
- fix parsing of end of lines in some cases
- do not take the case into account when comparing environment variable names
Add AppVeyor CI
Better error message in case a chain of dependencies crosses the installed world
Better error messages for invalid dependency list in jbuild files
Several improvements/fixes regarding the handling of findlib packages:
- Better error messages when a findlib package is unavailable
- Don't crash when an installed findlib package has missing dependencies
- Handle the findlib alternative directory layout which is still used by a few packages
Add jbuilder installed-libraries --not-available explaining why some libraries are not available
jbuilder now records dependencies on files of external libraries. This mean that when you upgrade a library, jbuilder will know what need to be rebuilt.
Add a jbuilder rules subcommand to dump internal compilation rules, mostly for debugging purposes
Ignore all directories starting with a . or _. This seems to be a common pattern:
- .git, .hg, _darcs
- _build
- _opam (opam 2 local switches)
Fix the hint for jbuilder external-lib-deps (#72)
Do not require ocamllex and ocamlyacc to be at the same location as ocamlc (#75)

1.0+beta8 (17/04/2017)

Added ${lib-available:<library-name>} which expands to true or false with the same semantic as literals in (select ...) stanzas
Remove hard-coded knowledge of a few specific ppx rewriters to ease maintenance moving forward
Pass the library name to ppx rewriters via the library-name cookie
Fix: make sure the action working directory exist before running it

1.0+beta7 (12/04/2017)

Make the output quieter by default and add a --verbose argument (@stedolan, #40)
Various documentation fixes (@adrieng, #41)
Make @install the default target when no targets are specified (@stedolan, #47)
Add predefined support for menhir, similar to ocamlyacc support (@rgrinberg, #42)
Add internal support for sandboxing actions and sandbox the build of the alias module with 4.02 to workaround the compiler trying to read the cmi of the aliased modules
Allow to disable dynlink support for libraries via (no_dynlink) (#55)
Add a -p/--for-release-of-packages command line argument to simplify the jbuilder invocation in opam files and make it more future proof (#52)
Fix the lookup of the executable in jbuilder exec foo. Before, even if foo was to be installed, the freshly built version wasn't selected
Don't generate a exists_if ... lines in META files. These are useless sine the META files are auto-generated

1.0+beta6 (29/03/2017)

Add an (executable ...) stanza for single executables (#33)
Add a (package ...) and (public_name <name>)/(public_names (<names)) to executable/executables stanzas to make it easier to install executables (#33)
Fix a bug when using specific rewriters that jbuilder knows about without ppx_driver.runner (#37). These problem should go away soon when we start using --cookie
Fix the interpretation of META files when there is more than one applicable assignment. Before this fix, the one with the lowest number of formal predicates was selected instead of the one with the biggest number of formal predicates

1.0+beta5 (22/03/2017)

When ocamlfind is present in the PATH, do not attempt to call opam config var lib
Make sure the build of jbuilder itself never calls ocamlfind or opam
Better error message when a jbuild file in OCaml syntax forgets to call Jbuild_plugin.V*.send
Added examples of use
Don't drop inline tests/benchmarks by default

1.0+beta4 (20/03/2017)

Improve error messages about invalid/missing pkg.opam files
Ignore all errors while running ocamlfind printconf path

1.0+beta3 (15/03/2017)

Print optional dependencies as optional in the output of jbuilder external-lib-deps --missing
Added a few forms to the DSL:
- with-{stderr,outputs}-to
- ignore-{stdout,stderr,outputs}
Added ${null} which expands to /dev/null on Unix and NUL on Windows
Improve the doc generated by odoc for wrapped libraries
Improve the error reported when an installed package depends on a library that is not installed
Documented (files_recursively_in ...)
Added black box tests
Fix a bug where jbuilder would crash when there was no <package>.opam file
Fixed a bug where .merlin files where not generated at the root of the workspace (#20)
Fix a bug where a (glob_files ...) would cause other dependencies to be ignored
Fix the generated ppx(...) line in META files
Fix (optional) when a ppx runtime dependency is not available (#24)
Do not crash when an installed package that we don't need has missing dependencies (#25)

1.0+beta2 (10/03/2017)

Simplified the rules for finding the root of the workspace as the old ones were often picking up the home directory. New rules are:
- look for a jbuild-workspace file in parent directories
- look for a jbuild-workspace* file in parent directories
- use the current directory
Fixed the expansion of ${ROOT} in actions
Install quick-start.org in the documentation directory
Add a few more things in the log file to help debugging

1.0+beta1 (07/03/2017)

Added a manual
Support incremental compilation
Switched the CLI to cmdliner and added a build command (#5, @rgrinberg)
Added a few commands:
- runtest
- install
- uninstall
- installed-libraries
- exec: execute a command in an environment similar to what you would get after jbuilder install
Removed the build-package command in favor of a --only-packages option that is common to all commands
Automatically generate .merlin files (#2, @rdavison)
Improve the output of jbuilder, in particular don't mangle the output of commands when using -j N with N > 1
Generate a log in _build/log
Versioned the jbuild format and added a first stable version. You should now put (jbuilder_version 1) in a jbuild file at the root of your project to ensure forward compatibility
Switch from ppx_driver to ocaml-migrate-parsetree.driver. In order to use ppx rewriters with Jbuilder, they need to use ocaml-migrate-parsetree.driver
Added support for aliases (#7, @rgrinberg)
Added support for compiling against multiple opam switch simultaneously by writing a jbuild-worspace file
Added support for OCaml 4.02.3
Added support for architectures that don't have natdynlink
Search the root according to the rules described in the manual instead of always using the current directory
extended the action language to support common actions without using a shell:
- (with-stdout-to <file> <DSL>)
- (copy <src> <dst>)
- ...
Removed all implicit uses of bash or the system shell. Now one has to write explicitly (bash "...") or (system "...")
Generate meaningful versions in META files
Strengthen the scope of a package. Jbuilder knows about package foo only in the sub-tree starting from where foo.opam lives
