Hackage-only release with no user facing changes (added compatibility
- Stack can now be compiled again inside a directory that does not
.gitdirectory, see #4364
- Handle a change in GHC’s hi-dump format around
addDependentFile, which now includes a hash. See yesodweb/yesod#1551
- Allow variables to appear in template file names.
Hackage-only release with no user facing changes.
- Stack can now be compiled again inside a directory that does not
.gitdirectory, see #4364
- Statically linked Linux bindists are back again, thanks to @nh2.
- We will be deleting the Ubuntu, Debian, CentOS, Fedora, and Arch package repos from
download.fpcomplete.comsoon. These have been deprecated for over a year and have not received new releases, but were left in place for compatibility with older scripts.
- Upgrade to Cabal 2.4
- Note that, in this process, the behavior of file globbing has
been modified to match that of Cabal. In particular, this means
that for Cabal spec versions less than 2.4,

GHCJSsupport is being downgraded to ‘experimental’. A warning notifying the user of the experimental status of
GHCJSwill be displayed.
stack.yamlare now appended to
config.yaml, whereas before they would be replaced.
stack buildwill now announce when sublibraries of a package are being build, in the same way executables, tests, benchmarks and libraries are announced
stack sdistwill now announce the destination of the generated tarball, regardless of whether or not it passed the sanity checks
stack setuphas been deprecated. This feature no longer works with GHC 8.2 and later. Furthermore, the reason for this flag originally being implemented was drastically lessened once Stack started using the snapshot’s
Caballibrary for custom setups. See: #4070.
- With the new namespaced template feature,
stack templatesis no longer able to meaningfully display a list of all templates available. Instead, the command will download and display a help file with more information on how to discover templates. See: #4039
- Build tools are now handled in a similar way to
cabal-install. In particular, for legacy
build-toolsfields, we use a hard-coded list of build tools in place of looking up build tool packages in a tool map. This both brings Stack’s behavior closer into line with
cabal-install, avoids some bugs, and opens up some possible optimizations/laziness. See: #4125.
- Mustache templating is not applied to large files (over 50kb) to avoid performance degredation. See: #4133.
stack uploadsigns the package by default, as documented.
--no-signatureturns the signing off. #3739
- In case there is a network connectivity issue while trying to download a template, stack will check whether that template had been downloaded before. In that case, the cached version will be used. See #3850.
- On Windows before Windows 10, –color=never is the default on terminals that can support ANSI color codes in output only by emulation
- On Windows, recognise a ‘mintty’ (false) terminal as a terminal, by default
stack buildissues a warning when
baseis explicitly listed in
stack buildsuggests trying another GHC version should the build plan end up requiring unattainable
- A new sub command
runhas been introduced to build and run a specified executable similar to
cabal run. If no executable is provided as the first argument, it defaults to the first available executable in the project.
stack buildmissing dependency suggestions (on failure to construct a valid build plan because of missing deps) are now printed with their latest cabal file revision hash. See #4068.
- Added new
stack sdist, that allows to copy the resulting tarball to the specified directory.
- Introduced the
--interleaved-outputcommand line option and
build.interleaved-outputconfig value which causes multiple concurrent builds to dump to stderr at the same time with a
packagename>prefix. See #3225.
- The default retry strategy has changed to exponential backoff. This should help with #3510.
stack newnow allows template names of the form
username/footo download from a user other than
commercialstackon Github, and can be prefixed with the service
- Switch to
githashto include some unmerged bugfixes in
gitrevSuggestion to add
'allow-newer': truenow shows path to user config file where this flag should be put into #3685
stack ghcinow asks which main target to load before doing the build, rather than after
- Bump to hpack 0.29.0
- With GHC 8.4 and later, Haddock is given the
- It is possible to specify the Hackage base URL to upload packages to, instead
of the default of
https://hackage.haskell.org/, by using
- When using Nix, if a specific minor version of GHC is not requested, the latest minor version in the given major branch will be used automatically.
stack ghcinow does not invalidate
.ofiles on repeated runs, meaning any modules compiled with
-fobject-codewill be cached between ghci runs. See #4038.
stack.yamlterminating by newline
- The previous released caused a regression where some
ghc-pkgcommand showed up in the terminal. This output is now silenced.
- A regression in recompilation checking introduced in v1.7.1 has been fixed. See #4001
stack ghcion a package with internal libraries was erroneously looking for a wrong package corresponding to the internal library and failing to load any module. This has been fixed now and changes to the code in the library and the sublibrary are properly tracked. See #3926.
- For packages with internal libraries not depended upon,
stack buildused to fail the build process since the internal library was not built but it was tried to be registered. This is now fixed by always building internal libraries. See #3996.
--no-nixwas not respected under NixOS
- Fix a regression which might use a lot of RAM. See #4027.
- Order of commandline arguments does not matter anymore. See #3959
- When prompting users about saving their Hackage credentials on upload, flush to stdout before waiting for the response so the prompt actually displays. Also fixes a similar issue with ghci target selection prompt.
cabalis not on PATH, running
stack solvernow prompts the user to run
stack install cabal-install
stack buildnow succeeds in building packages which contain sublibraries which are dependencies of executables, tests or benchmarks but not of the main library. See #3787.
- Sublibraries are now properly considered for coverage reports when the test suite depends on the internal library. Before, stack was erroring when trying to generate the coverage report, see #4105.
- Sublibraries are now added to the precompiled cache and recovered from there when the snapshot gets updated. Previously, updating the snapshot when there was a package with a sublibrary in the snapshot resulted in broken builds. This is now fixed, see #4071.
- #4114 Stack pretty prints error messages with proper
errorlogging level instead of
warningnow. This also fixes self-executing scripts not piping plan construction errors from runhaskell to terminal (issue #3942).
- Fix invalid “While building Setup.hs” when Cabal calls fail. See: #3934
stack uploadsigns the package by default, as documented.
--no-signatureturns the signing off. #3739
- aarch64 (64-bit ARM) bindists are now available for the first time.
- Statically linked Linux bindists are no longer available, due to difficulty with GHC 8.2.2 on Alpine Linux.
- 32-bit Linux GMP4 bindists for CentOS 6 are no longer available, since GHC 8.2.2 is no longer being built for that platform.
- Upgrade from Cabal 2.0 to Cabal 2.2
stack setupno longer uses different GHC configure options on Linux distributions that use GCC with PIE enabled by default. GHC detects this itself since ghc-8.0.2, and Stack’s attempted workaround for older versions caused more problems than it solved.
stack newno longer initializes a project if the project template contains a stack.yaml file.
- A new sub command
lshas been introduced to stack to view local and remote snapshots present in the system. Use
stack ls snapshots --helpto get more details about it.
list-dependencieshas been deprecated. The functionality has to accessed through the new
ls dependenciesinterface. See #3669 for details.
- Specify User-Agent HTTP request header on every HTTP request. See #3628 for details.
stack setuplooks for GHC bindists and installations by any OS key that is compatible (rather than only checking a single one). This is relevant on Linux where different distributions may have different combinations of libtinfo 5/6, ncurses 5/6, and gmp 4/5, and will allow simpifying the setup-info metadata YAML for future GHC releases.
- The build progress bar reports names of packages currently building.
stack setup --verbosecauses verbose output of GHC configure process. See #3716
- Improve the error message when an
extra-depfrom a path or git reference can’t be found See #3808
- Nix integration is now disabled on windows even if explicitly enabled, since it isn’t supported. See #3600
stack buildnow supports a new flag
--keep-tmp-filesto retain intermediate files and directories for the purpose of debugging. It is best used with ghc’s equivalent flag, i.e.
stack build --keep-tmp-files --ghc-options=-keep-tmp-files. See #3857
- Improved error messages for snapshot parse exceptions
stack unpacknow supports a
--to /target/directoryoption to specify where to unpack the package into
stack hooglenow supports a new flag
--serverthat launches local Hoogle server on port 8080. See #2310
- The script interpreter’s implicit file arguments are now passed before other
arguments. See #3658.
In particular, this makes it possible to pass
-- +RTS ... -RTSto specify RTS arguments used when running the script.
- Don’t ignore the template
yearparameter in config files, and clarify the surrounding documentation. See #2275.
- Benchmarks used to be run concurrently with other benchmarks and build steps. This is non-ideal because CPU usage of other processes may interfere with benchmarks. It also prevented benchmark output from being displayed by default. This is now fixed. See #3663.
stack ghcinow allows loading multiple packages with the same module name, as long as they have the same filepath. See #3776.
stack ghcino longer always adds a dependency on
base. It is now only added when there are no local targets. This allows it to be to load code that uses replacements for
base. See #3589
stack ghcinow uses correct paths for autogen files with #3791
- When a package contained sublibraries, stack was always recompiling the package. This has been fixed now, no recompilation is being done because of sublibraries. See #3899.
get-stack.shinstall script now matches manual instructions when it comes to Debian/Fedora/CentOS install dependencies.
- Compile Cabal-simple with gmp when using Nix. See #2944
stack ghcinow replaces the stack process with ghci. This improves signal handling behavior. In particular, handling of Ctrl-C. To make this possible, the generated files are now left behind after exit. The paths are based on hashing file contents, and it’s stored in the system temporary directory, so this shouldn’t result in too much garbage. See #3821.
- Some unnecessary rebuilds when no files were changed are now avoided, by having a separate build cache for each component of a package. See #3732.
- Correct the behavior of promoting a package from snapshot to local package. This would get triggered when version bounds conflicted in a snapshot, which could be triggered via Hackage revisions for old packages. This also should allow custom snapshots to define conflicting versions of packages without issue. See Stackage issue #3185.
- When promoting packages from snapshot to local, we were occassionally discarding the actual package location content and instead defaulting to pulling the package from the index. We now correctly retain this information. Note that if you were affected by this bug, you will likely need to delete the binary build cache associated with the relevant custom snapshot. See #3714.
--no-rerun-testshas been fixed. Previously, after running a test we were forgetting to record the result, which meant that all tests always ran even if they had already passed before. See #3770.
- Includes a patched version of
hackage-securitywhich fixes both some issues around asynchronous exception handling, and moves from directory locking to file locking, making the update mechanism resilient against SIGKILL and machine failure. See hackage-security #187 and #3073.
Hackage-only release with no user facing changes (updated to build with newer version of hpack dependency).
- In addition to supporting
.zipfiles as remote archives, plain
.tarfiles are now accepted too. This will additionally help with cases where HTTP servers mistakenly set the transfer encoding to
gzip. See #3647.
- Links to docs.haskellstack.org ignore Stack version patchlevel.
- Downloading Docker-compatible
stackbinary ignores Stack version patchlevel.
- For versions of Cabal before 1.24, ensure that the dependencies of non-buildable components are part of the build plan to work around an old Cabal bug. See #3631.
- Run the Cabal file checking in the
sdistcommand more reliably by allowing the Cabal library to flatten the
Hackage-only release with no user facing changes (updated to build with newer dependency versions).
- Complete overhaul of how snapshots are defined, the
extra-depsfields, and a number of related items. For full details, please see the writeup on these changes. PR #3249, see the PR description for a number of related issues.
- Upgraded to version 2.0 of the Cabal library.
--install-ghcflag is now on by default. For example, if you run
stack buildin a directory requiring a GHC that you do not currently have, Stack will automatically download and install that GHC. You can explicitly set
install-ghc: falseor pass the flag
--no-install-ghcto regain the previous behavior.
stack ghcino longer loads modules grouped by package. This is always an improvement for plain ghci - it makes loading faster and less noisy. For intero, this has the side-effect that it will no longer load multiple packages that depend on TH loading relative paths. TH relative paths will still work when loading a single package into intero. See #3309
- Setting GHC options for a package via
stack.yamlwill promote it to a local package, providing for more consistency with flags and better reproducibility. See: #849
package-indicessetting with Hackage no longer works with the
00-index.tar.gztarball, but must use the
01-index.tar.gzfile to allow revised packages to be found.
- Options passed via
--ghci-optionsare now passed to the end of the invocation of ghci, instead of the middle. This allows using
+RTSwithout an accompanying
- When auto-detecting
tinfo6is now preferred over
standardif both versions of libtinfo are installed
- Addition of
stack build --copy-compiler-tool, to allow tools like intero to be installed globally for a particular compiler. #2643
- Stack will ask before saving hackage credentials to file. This new
prompt can be avoided by using the
save-hackage-credssetting. Please see #2159.
GHCRTSenvironment variable will no longer be passed through to every program stack runs. Instead, it will only be passed through commands like
ghci, etc. See #3444.
ghc-options:for specific packages will now come after the options specified for all packages / particular sets of packages. See #3573.
pvp-boundsfeature is no longer fully functional, due to some issues with the Cabal library’s printer. See #3550.
with-hpackconfiguration option specifies an Hpack executable to use instead of the Hpack bundled with Stack. Please see #3179.
- It’s now possible to skip tests and benchmarks using
StaticSHA256and is implemented using the
StaticSize 64 ByteStringfor improved performance. See #3006
- Dependencies via HTTP(S) archives have been generalized to allow local file path archives, as well as to support setting a cryptographic hash (SHA256) of the contents for better reproducibility.
- Allow specifying
- When running
stack upgradefrom a file which is different from the default executable path (e.g., on POSIX systems,
~/.local/bin/stack), it will now additionally copy the new executable over the currently running
stackexecutable. If permission is denied (such as in
/usr/local/bin/stack), the user will be prompted to try again using
sudo. This is intended to assist with the user experience when the
PATHenvironment variable has not been properly configured, see #3232.
stack setupfor ghcjs will now install
happyif they are not present. See #3109.
stack ghci --only-mainflag, to skip loading / importing all but main modules. See the ghci documentation page for further info.
- Allow GHC’s colored output to show through. GHC colors output
starting with version 8.2.1, for older GHC this does nothing.
Sometimes GHC’s heuristics would work fine even before this change,
for example in
stack ghci, but this override’s GHC’s heuristics when they’re broken by our collecting and processing GHC’s output.
- Extended the
ghc-optionsfield to support
$everything. See: #3329
- Better error message for case that
stack ghcifile targets are combined with invalid package targets. See: #3342
- For profiling now uses
-fprof-auto -fprof-cafsinstead of the deprecated
-auto-all -caf-all. See: #3360
- Better descriptions are now available for
stack upgrade --help. See: #3070
- When using Nix, nix-shell now depends always on gcc to prevent build errors when using the FFI. As ghc depends on gcc anyway, this doesn’t increase the dependency footprint.
--cwd DIRcan now be passed to
stack execin order to execute the program in a different directory. See: #3264
- Plan construction will detect if you add an executable-only package as a library dependency, resulting in much clearer error messages. See: #2195.
- Addition of
stack scriptto pass options directly to GHC. See: #3454
- Add hpack
package.yamlto build Stack itself
ignore-revision-mismatchsetting. See: #3520.
- Log when each individual test suite finishes. See: #3552.
- Avoid spurious rebuilds when using
--file-watchby not watching files for executable, test and benchmark components that aren’t a target. See: #3483.
- Stack will now try to detect the width of the running terminal
(only on POSIX for the moment) and use that to better display
output messages. Work is ongoing, so some messages will not
be optimal yet. The terminal width can be overridden with the
--terminal-widthcommand-line option (this works even on non-POSIX).
- Passing non local packages as targets to
stack ghciwill now cause them to be used as
-packageargs along with package hiding.
- Detect when user changed .cabal file instead of package.yaml. This was implemented upstream in hpack. See #3383.
- Automatically run
autoreconf -ias necessary when a
configurescript is missing. See #3534
- GHC bindists can now be identified by their SHA256 checksum in addition to their SHA1 checksum, allowing for more security in download.
- For filesystem setup-info paths, it’s no longer assumed that the directory is writable, instead a temp dir is used. See #3188.
stack hooglecorrectly generates Hoogle databases. See: #3362
stack --docker-helpis now clearer about –docker implying system-ghc: true, rather than both –docker and –no-docker.
stack haddocknow includes package names for all modules in the Haddock index page. See: #2886
- Fixed an issue where Stack wouldn’t detect missing Docker images properly with newer Docker versions. #3171
- Previously, cabal files with just test-suite could cause build to fail (#2862)
- If an invalid snapshot file has been detected (usually due to mismatched hashes), Stack will delete the downloaded file and recommend either retrying or filing an issue upstream. See #3319.
- Modified the flag parser within Stack to match the behavior of Cabal’s flag parser, which allows multiple sequential dashes. See #3345
- Now clears the hackage index cache if it is older than the downloaded index. Fixes potential issue if stack was interrupted when updating index. See #3033
- The Stack install script now respects the
-doption. See #3366.
stack scriptcan now handle relative paths to source files. See #3372.
- Fixes explanation of why a target is needed by the build plan, when the target is an extra dependency from the commandline. See #3378.
- Previously, if you delete a yaml file from ~/.stack/build-plan, it would trust the etag and not re-download. Fixed in this version.
stack --dockerin parallel now correctly locks the sqlite database. See #3400.
- docs.haskellstack.org RTD documentation search is replaced by the mkdocs search. Please see #3376.
stack cleannow works with nix. See #3468.
stack build --only-dependenciesno longer builds local project packages that are depended on. See #3476.
- Properly handle relative paths stored in the precompiled cache files. See #3431.
- In some cases, Cabal does not realize that it needs to reconfigure, and must be told to do so automatically. This would manifest as a “shadowed dependency” error message. We now force a reconfigure whenever a dependency is built, even if the package ID remained the same. See #2781.
--pvp-boundsis enabled for sdist or upload, internal dependencies could cause errors when uploaded to hackage. This is fixed, see #3290
- Fixes a bug where nonexistent hackage versions would cause stack to suggest the same package name, without giving version info. See #3562
- Fixes a bug that has existed since 1.5.0, where
stack setup --upgrade-cabalwould say that Cabal is already the latest version, when it wasn’t.
- Ensure that an
extra-depfrom a local directory is not treated as a
$localsfor GHC options purposes. See #3574.
- Building all executables only happens once instead of every time. See #3229 for more info.
- Stack eagerly tries to parse all cabal files related to a
snapshot. Starting with Stackage Nightly 2017-07-31, snapshots are
using GHC 8.2.1, and the
ghc.cabalfile implicitly referenced uses the (not yet supported) Cabal 2.0 file format. Future releases of Stack will both be less eager about cabal file parsing and support Cabal 2.0. This patch simply bypasses the error for invalid parsing.
stack tracenow add their extra RTS arguments for benchmarks and tests to the beginning of the args, instead of the end. See #2399
- Support for Git-based indices has been removed.
stack setupallow to control options passed to ghcjs-boot with
--ghcjs-boot-options(one word at a time) and
stack setupnow accepts a
--install-cabal VERSIONoption which will install a specific version of the Cabal library globally.
- Updates to store-0.4.1, which has improved performance and better error reporting for version tags. A side-effect of this is that all of stack’s binary caches will be invalidated.
stack solverwill now warn about unexpected cabal-install versions. See #3044
- Upstream packages unpacked to a temp dir are now deleted as soon as
possible to avoid running out of space in
/tmp. See #3018
- Add short synonyms for
STACK_WORKenvironment variable, to specify work dir. See #3063
- Can now use relative paths for
extra-lib-dirs. See #2830
- Improved bash completion for many options, including
--flag, targets, and project executables for
--haddock-argumentsis actually used now when
haddockis invoked during documentation generation.
--[no-]haddock-hyperlink-sourceflag added which allows toggling of sources being included in Haddock output. See #3099
stack ghciwill now skip building all local targets, even if they have downstream deps, as long as it’s registered in the DB.
- The pvp-bounds feature now supports adding
-revisionto the end of each value, e.g.
pvp-bounds: both-revision. This means that, when uploading to Hackage, Stack will first upload your tarball with an unmodified
.cabalfile, and then upload a cabal file revision with the PVP bounds added. This can be useful—especially combined with the Stackage no-revisions feature—as a method to ensure PVP compliance without having to proactively fix bounds issues for Stackage maintenance.
- Expose a
- On GHC <= 7.8, filters out spurious linker warnings on windows See #3127
- Better error messages when creating or building packages which alias wired-in packages. See #3172.
- MinGW bin folder now is searched for dynamic libraries. See #3126
- When using Nix, nix-shell now depends always on git to prevent runtime errors while fetching metadata
stack unpackcommand now accepts a form where an explicit Hackage revision hash is specified, e.g.
stack unpack foo-1.2.3@gitsha1:deadbeef. Note that this should be considered experimental, Stack will likely move towards a different hash format in the future.
- Binary “stack upgrade” will now warn if the installed executable is not on the PATH or shadowed by another entry.
- Allow running tests on tarball created by sdist and upload #717.
- Fixes case where
stack build --profilemight not cause executables / tests / benchmarks to be rebuilt. See #2984
stack ghci file.hsnow loads the file even if it isn’t part of your project.
stack clean --fullnow works when docker is enabled. See #2010
- Fixes an issue where cyclic deps can cause benchmarks or tests to be run before they are built. See #2153
stack build --file-watchin cases where a directory is removed See #1838
stack list-dependenciesto use info from the package database for wired-in-packages (ghc, base, etc). See #3084
stack --docker buildwhen user is part of libvirt/libvirtd groups on Ubuntu Yakkety (16.10). See #3092
- Switching a package between extra-dep and local package now forces rebuild (previously it wouldn’t if versions were the same). See #2147
stack uploadno longer reveals your password when you type it on MinTTY-based Windows shells, such as Cygwin and MSYS2. See #3142
stack script’s import parser will now properly parse files that have Windows-style line endings (CRLF)
- Docker images: fpco/stack-full and fpco/stack-run are no longer being built for LTS 8.0 and above. fpco/stack-build images continue to be built with a simplified process. #624
- A new command,
script, has been added, intended to make the script interpreter workflow more reliable, easier to use, and more efficient. This command forces the user to provide a
--resolvervalue, ignores all config files for more reproducible results, and optimizes the existing package check to make the common case of all packages already being present much faster. This mode does require that all packages be present in a snapshot, however. #2805
The default package metadata backend has been changed from Git to the 01-index.tar.gz file, from the hackage-security project. This is intended to address some download speed issues from Github for people in certain geographic regions. There is now full support for checking out specific cabal file revisions from downloaded tarballs as well. If you manually specify a package index with only a Git URL, Git will still be used. See #2780
When you provide the
--resolverargument to the
stack unpackcommand, any packages passed in by name only will be looked up in the given snapshot instead of taking the latest version. For example,
stack --resolver lts-7.14 unpack mtlwill get version 2.2.1 of
mtl, regardless of the latest version available in the package indices. This will also force the same cabal file revision to be used as is specified in the snapshot.
Unpacking via a package identifier (e.g.
stack --resolver lts-7.14 unpack mtl-2.2.1) will ignore any settings in the snapshot and take the most recent revision.
For backwards compatibility with tools relying on the presence of a
00-index.tar, Stack will copy the
00-index.tar. Note, however, that these files are different; most importantly, 00-index contains only the newest revisions of cabal files, while 01-index contains all versions. You may still need to update your tooling.
--(no-)nix-*options now no longer implies
--nix, except for
--nix-pure, so that the user preference whether or not to use Nix is honored even in the presence of options that change the Nix behavior.
- Internal cleanup: configuration types are now based much more on lenses
stack buildand related commands now allow the user to disable debug symbol stripping with new
--no-executable-shippingflags, closing #877. Also turned error message for missing targets more readable (#2384)
stack haddocknow shows index.html paths when documentation is already up to date. Resolved #781
- Respects the
custom-setupfield introduced in Cabal 1.24. This supercedes any
explicit-setup-depssettings in your
stack.yamland trusts the package’s
.cabalfile to explicitly state all its dependencies.
- If system package installation fails,
get-stack.shwill fail as well. Also shows warning suggesting to run
apt-get updateor similar, depending on the OS. (#2898)
stack ghciis run with a config with no packages (e.g. global project), it will now look for source files in the current work dir. (#2878)
- Bump to hpack 0.17.0 to allow
- The script interpreter will now output error logging. In particular, this means it will output info about plan construction errors. (#2879)
stack ghcinow takes
--ghc-optionsagain (inadvertently removed in 1.3.0). (#2986)
stack execnow takes
--rts-optionswhich passes the given arguments inside of
+RTS ... args .. -RTSto the executable. This works around stack itself consuming the RTS flags on Windows. (#2640)
http-client-tlsversion, which now offers support for the
socks5h://values in the
- Bump to hpack 0.16.0 to avoid character encoding issues when reading and writing on non-UTF8 systems.
stack ghciwill no longer ignore hsSourceDirs that contain
stack list-dependencies --licensenow works for wired-in-packages, like base. (#2871)
stack setupnow correctly indicates when it uses system ghc (#2963)
- Fix to
stack config set, in 1.3.2 it always applied to the global project. (#2709)
- Previously, cabal files without exe or lib would fail on the “copy” step. (#2862)
stack upgrade --gitnow works properly. Workaround for affected versions (>= 1.3.0) is to instead run
stack upgrade --git --source-only. (#2977)
- Added support for GHC 8’s slightly different warning format for dumping warnings from logs.
- Work around a bug in Cabal/GHC in which package IDs are not unique for different source code, leading to Stack not always rebuilding packages depending on local packages which have changed. (#2904)
stack config setcan now be used without a compiler installed #2852.
get-stack.shnow installs correct binary on ARM for generic linux and raspbian, closing #2856.
- Correct the testing of whether a package database exists by checking
package.cachefile itself instead of the containing directory.
- Revert a change in the previous release which made it impossible to set local extra-dep packages as targets. This was overkill; we really only wanted to disable their test suites, which was already handled by a later patch. #2849
stack newalways treats templates as being UTF-8 encoding, ignoring locale settings on a local machine. See Yesod mailing list discussion
- For the next stack release after this one, we are planning
changes to our Linux releases, including dropping our Ubuntu,
Debian, CentOS, and Fedora package repositories and switching to
statically linked binaries. See
Note that upgrading without a package manager has gotten easier
with new binary upgrade support in
stack upgrade(see the Major Changes section below for more information). In addition, the get.haskellstack.org script no longer installs from Ubuntu, Debian, CentOS, or Fedora package repositories. Instead it places a generic binary in /usr/local/bin.
Stack will now always use its own GHC installation, even when a suitable GHC installation is available on the PATH. To get the old behaviour, use the
--system-ghcflag or run
stack config set system-ghc --global true. Docker- and Nix-enabled projects continue to use the GHC installations in their environment by default.
NB: Scripts that previously used stack in combination with a system GHC installation should now include a
stack setupline or use the
stack ghcinow defaults to skipping the build of target packages, because support has been added for invoking “initial build steps”, which create autogen files and run preprocessors. The
--no-buildflag is now deprecated because it should no longer be necessary. See #1364
Stack is now capable of doing binary upgrades instead of always recompiling a new version from source. Running
stack upgradewill now default to downloading a binary version of Stack from the most recent release, if one is available. See
stack upgrade --helpfor more options. #1238
--resolver Xwith a Stack command which forces creation of a global project config, will pass resolver X into the initial config. See #2579.
Switch the “Run from outside project” messages to debug-level, to avoid spamming users in the normal case of non-project usage
If a remote package is specified (such as a Git repo) without an explicit
extra-depsetting, a warning is given to the user to provide one explicitly.
stack haddocknow supports

ghc-buildoption to override autodetected GHC build to use (e.g. gmp4, tinfo6, nopie) on Linux.
stack setupdetects systems where gcc enables PIE by default (such as Ubuntu 16.10 and Hardened Gentoo) and adjusts the GHC

- Upload to Hackage with HTTP digest instead of HTTP basic.
stack list-dependenciesunderstand all of the
stack dotoptions too.
- Add the ability for
stack list-dependenciesto list dependency licenses by passing the
- Dump logs that contain warnings for any local non-dependency packages #2545
- Add the
dump-logsconfig option and
--dump-logscommand line option to get full build output on the console. #426
- Add the
--openoption to “stack hpc report” command, causing the report to be opened in the browser.
stack config setcommand now accepts a
--globalflag for suitable fields which causes it to modify the global user configuration (
~/.stack/config.yaml) instead of the project configuration. #2675
- Information on the latest available snapshots is now downloaded from S3 instead of stackage.org, increasing reliability in case of stackage.org outages. #2653
stack list-dependenciesnow take targets and flags. #1919
stack setup --stack-setup-yamlfor
--setup-info-yamlbased on discussion in #2647.
--main-isflag for GHCI now implies the TARGET, fixing #1845.

- No longer warns about missing build-tools if they are on the PATH. #2235
- Replace enclosed-exceptions with safe-exceptions. #2768
- The install location for GHC and other programs can now be configured with the
- Added option to add nix dependencies as nix GC roots
- Proper pid 1 (init) process for
stack execwith Docker
- Dump build logs if they contain warnings. #2545
- Docker: redirect stdout of
docker pullto stderr so that it will not interfere with output of other commands.
- Nix & docker can be activated at the same time, in order to run stack in a nix-shell in a container, preferably from an image already containing the nix dependencies in its /nix/store
- Stack/nix: Dependencies can be added as nix GC roots, so they are not removed
- Fixed a gnarly bug where programs and package tarballs sometimes have corrupted downloads. See #2657.
- Add proper support for non-ASCII characters in file paths for the
sdistcommand. See #2549
- Never treat
extra-deplocal packages as targets. This ensures things like test suites are not run for these packages, and that build output is not hidden due to their presence.
- Fix a resource leak in
sinkProcessStderrStdoutwhich could affect much of the codebase, in particular copying precompiled packages. #1979
- Docker: ensure that interrupted extraction process does not cause corrupt file when downloading a Docker-compatible Stack executable #2568
- Fixed running
stack hpc reporton package targets. #2664
- Fix a long-standing performance regression where stack would parse the .dump-hi files of the library components of local packages twice. #2658
- Fixed a regression in “stack ghci –no-load”, where it would prompt for a main module to load. #2603
- Build Setup.hs files with the threaded RTS, mirroring the behavior of cabal-install and enabling more complex build systems in those files.
- Fixed a bug in passing along
--ghc-optionsto ghcjs. They were being provided as
--ghc-optionsto Cabal, when it needs to be
- Launch Docker from the project root regardless of the working
directory Stack is invoked from. This means paths relative to the project root
(e.g. environment files) can be specified in
stack setup --reinstallnow behaves as expected. #2554
On many Un*x systems, Stack can now be installed with a simple one-liner:
wget -qO- https://get.haskellstack.org/ | sh
The fix for #2175 entails that stack must perform a full clone of a large Git repo of Hackage meta-information. The total download size is about 200 MB. Please be aware of this when upgrading your stack installation.
If you use Mac OS X, you may want to delay upgrading to macOS Sierra as there are reports of GHC panics when building some packages (including Stack itself). See #2577
This version of Stack does not build on ARM or PowerPC systems (see store#37). Please stay with version 1.1.2 for now on those architectures. This will be rectified soon!
We are now releasing a statically linked Stack binary for 64-bit Linux. Please try it and let us know if you run into any trouble on your platform.
We are planning some changes to our Linux releases, including dropping our Ubuntu, Debian, CentOS, and Fedora package repositories and switching to statically linked binaries. We would value your feedback in #2534.

exec ghciinstead of
runghcin the shebang command. #2510
- Now consider a package to be dirty when an extra-source-file is changed. See #2040
- Extensible custom snapshots implemented. These allow you to define snapshots which extend other snapshots. See #863. Local file custom snapshots can now be safely updated without changing their name. Remote custom snapshots should still be treated as immutable.
stack path --compilerwas added in the last release, to yield a path to the compiler. Unfortunately,
--compileris a global option that is useful to use with
stack path. The same functionality is now provided by
stack path --compiler-exe. See #2123
- For packages specified in terms of a git or hg repo, the hash used in the location has changed. This means that existing downloads from older stack versions won’t be used. This is a side-effect of the fix to #2133
stack upgradeno longer pays attention to local stack.yaml files, just the global config and CLI options. #1392

stack initnow ignores symlinks when searching for cabal files. It also now ignores any directory that begins with
.(as well as
distdirs) - before it would only ignore
- The stack executable is no longer built with
-rtsopts. Before, when
-rtsoptswas enabled, stack would process
+RTSoptions even when intended for some other program, such as when used with
stack exec -- prog +RTS. See #2022.
stack path --ghc-pathsoption is deprecated and renamed to
--compileris added, which points directly at the compiler used in the current project.
--compiler-binpoints to the compiler’s bin dir.
- For consistency with the
$STACK_ROOTenvironment variable, the
stack path --global-stack-rootflag and the
global-stack-rootfield in the output of
stack pathare being deprecated and replaced with the
stack-rootflag and output field. Additionally, the stack root can now be specified via the
--stack-rootcommand-line flag. See #1148.
stack sigGPG-related sub-commands were removed (folded into
- GPG signing of packages while uploading to Hackage is now the default. Use
upload --no-signatureif you would rather not contribute your package signature. If you don’t yet have a GPG keyset, read this blog post on GPG keys. We can add a stack.yaml config setting to disable signing if some people desire it. We hope that people will sign. Later we will be adding GPG signature verification options.
stack build pkg-1.2.3will now build even if the snapshot has a different package version - it is treated as an extra-dep.
stack build local-pkg-1.2.3is an error even if the version number matches the local package #2028.
- Having a
nix:section no longer implies enabling nix build. This allows the user to globally configure whether nix is used (unless the project overrides the default explicitly). See #1924.
- Remove deprecated valid-wanted field.
- Docker: mount home directory in container #1949.

- On each run, stack will test the stack root directory (~/.stack), and the
project and package work directories (.stack-work) for whether they are
owned by the current user and abort if they are not. This precaution can
be disabled with the
allow-different-useroption in the global config (~/.stack/config.yaml). #471

- We’re calling this version 1.0.0 in preparation for Stackage LTS 4. Note, however, that this does not mean the code’s API will be stable as this is primarily an end-user tool.
- Added flag
--profileflag: passed with
stack build, it will enable profiling, and for
--testit will generate a profiling report by passing
+RTS -pto the executable(s). Great for using like
stack build --bench --profile(remember that enabling profile will slow down your benchmarks by >4x). Run
stack build --benchagain to disable the profiling and get proper speeds
- Added flag
--traceflag: just like
--profile, it enables profiling, but instead of generating a report for
--test, prints out a stack trace on exception. Great for using like
stack build --test --trace

- Fix: unlisted files in tests and benchmarks trigger extraneous second build #838
stack setupnow supports building and booting GHCJS from source tarball.
- On Windows, build directories no longer display “pretty” information (like x86_64-windows/Cabal-220.127.116.11), but rather a hash of that content. The reason is to avoid the 260 character path limitation on Windows. See #1027
- Rename config files and clarify their purposes #969
- Old locations still supported, with deprecation warnings
- New command “stack eval CODE”, which evaluates to “stack exec ghc – -e CODE”.

set-useroption to enable/disable running containerized processes as host’s UID/GID #194
- Custom Setup.hs files are now precompiled instead of interpreted. This should be a major performance win for certain edge cases (biggest example: building Cabal itself) while being either neutral or a minor slowdown for more common cases.
stack test --coveragenow also generates a unified coverage report for multiple test-suites / packages. In the unified report, test-suites can contribute to the coverage of other packages.

stack setupdue to the centos6 GHC bindist being treated like a variant
- A new
--pvp-boundsflag to the sdist and upload commands allows automatic adding of PVP upper and/or lower bounds to your dependencies
- Adapt to upcoming Cabal installed package identifier format change #851
stack setuptakes a
--file-watchis more discerning about which files to rebuild for #912
stack pathnow supports
--reconfigureflag #914 #946
- Cached data is written with a checksum of its structure #889
- Fully removed
--file-watch-pollflag for polling instead of using filesystem events (useful for running tests in a Docker container while modifying code in the host environment. When code is injected into the container via a volume, the container won’t propagate filesystem events).
- Give a preemptive error message when
-profis given as a GHC option #1015
- Locking is now optional, and will be turned on by setting the
STACK_LOCKenvironment variable to
- Create default stack.yaml with documentation comments and commented out options #226

Fix stack’s own Haddocks. No changes to functionality (only comments updated).
- You now have more control over how GHC versions are matched, e.g. “use exactly this version,” “use the specified minor version, but allow patches,” or “use the given minor version or any later minor in the given major release.” The default has switched from allowing newer later minor versions to a specific minor version allowing patches. For more information, see #736 and #784.
- Support added for compiling with GHCJS
- stack can now reuse prebuilt binaries between snapshots. That means that, if you build package foo in LTS-3.1, that binary version can be reused in LTS-3.2, assuming it uses the same dependencies and flags. #878
- Added the
--docker-envargument, to set environment variables in Docker container.
- Set locale environment variables to UTF-8 encoding for builds to avoid “commitBuffer: invalid argument” errors from GHC #793
