Module documentation for 0.1.4.1
The Haskell Tool Stack
Stack is a cross-platform program for developing Haskell projects. It is intended for Haskellers both new and experienced.
See haskellstack.org or the
doc directory for more
1.6.1 introduced a change that made some precompiled cache files use
longer paths, sometimes causing builds to fail on windows. This has been
fixed. See #3649
Some unnecessary rebuilds when no files were changed are now avoided, by
having a separate build cache for each component of a package. See
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
--no-rerun-tests has 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
Includes a patched version of
hackage-security which 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-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)
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 #2534. 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
--haddock-internal. See #2229
- Add support for

- 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.

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 ghcinow uses
:load, making it potentially work better with user scripts. See #1888

qAddDependentFileare now checked for dirtiness. See #1982
- Signing: always use
- Added Ubuntu 16.04 LTS (xenial) Apt repo.
- No longer uploading new versions to Fedora 21 repo.
- Snapshot packages are no longer built with executable profiling. See #1179.
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.
stack image: allow absolute source paths for
stack haddock --open [PACKAGE]opens the local haddocks in the browser.

Fixes build with aeson-0.11.0.0. There are no changes in behaviour from 1.0.4, so no binaries are released for this version.
- Some notable changes in
- Overall it should now be able to initialize almost all existing cabal packages out of the box as long as the package itself is consistently defined.
- Choose the best possible snapshot and add extra dependencies on top of a snapshot resolver rather than a compiler resolver - #1583

- 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

- The locations of the
package repositories have changed to have correct URL semantics according to
#1378. The old
locations will continue to work for some months, but we suggest that you
/etc/apt/sources.list.d/fpco.listto the new location to avoid future disruption.

stack setupnow supports building and booting GHCJS from source tarball.
- On Windows, build directories no longer display "pretty" information (like x86_64-windows/Cabal-18.104.22.168), 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".

giton Windows #1046. You can still get this behavior by running the following yourself:
stack exec -- pacman -Sy --noconfirm git.
- Typing enter during --file-watch triggers a rebuild #1023
- Use Haddock's
--hyperlinked-source(crosslinked source), if available #1070
- Use Stack-installed GHCs for
stack init --solver#1072
- New experimental
stack querycommand #1087
- By default, stack no longer rebuilds a package due to GHC options changes. This behavior can be tweaked with the
- By default, ghc-options are applied to all local packages, not just targets. This behavior can be tweaked with the
- Docker: download or override location of stack executable to re-run in container #974
- Docker: when Docker Engine is remote, don't run containerized processes as host's UID/GID #194
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.
- Ignore stack-built executables named
- Fix quoting of output failed command line arguments
- Mark executable-only packages as installed when copied from cache #1043
- Canonicalize temporary directory paths #1047

- Precompiled cache checks full package IDs on Cabal < 1.22 #1103
- Pass -package-id to ghci #867

- 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
