v1.5.0

See https://haskellstack.org for installation and upgrade instructions.

Behavior changes:

• stack profile and stack trace now 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.

Other enhancements:

• stack setup allow to control options passed to ghcjs-boot with
  --ghcjs-boot-options (one word at a time) and --[no-]ghcjs-boot-clean
• stack setup now accepts a --install-cabal VERSION option 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 solver will 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 test-arguments and benchmark-arguments options.
• Adds STACK_WORK environment variable, to specify work dir.
  See #3063
• Can now use relative paths for extra-include-dirs and extra-lib-dirs.
  See #2830
• Improved bash completion for many options, including --ghc-options,
  --flag, targets, and project executables for exec.
• --haddock-arguments is actually used now when haddock is invoked
  during documentation generation.
• --[no-]haddock-hyperlink-source flag added which allows toggling
  of sources being included in Haddock output.
  See #3099
• stack ghci will 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 -revision to 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 .cabal file, 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 save-hackage-creds configuration option
• 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
• The stack unpack command 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.

Bug fixes:

• Fixes case where stack build --profile might not cause executables /
  tests / benchmarks to be rebuilt.
  See #2984
• stack ghci file.hs now loads the file even if it isn't part of
  your project.
• stack clean --full now 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
• Fixes stack build --file-watch in cases where a directory is removed
  See #1838
• Fixes stack dot and stack list-dependencies to use info from the
  package database for wired-in-packages (ghc, base, etc).
  See #3084
• Fixes stack --docker build when 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 upload no 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)

v1.4.0

See https://haskellstack.org for installation and upgrade instructions.

Release notes:

• 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

Major changes:

• 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 --resolver
  value, 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

Behavior changes:

• 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 --resolver argument to the stack unpack
  command, 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 mtl will 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 01-index.tar file to
  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.

• Passing --(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.

Other enhancements:

• Internal cleanup: configuration types are now based much more on lenses
• stack build and related commands now allow the user to disable debug symbol stripping
  with new --no-strip, --no-library-stripping, and --no-executable-shipping flags,
  closing #877.
  Also turned error message for missing targets more readable (#2384)
• stack haddock now shows index.html paths when documentation is already up to
  date. Resolved #781
• Respects the custom-setup field introduced in Cabal 1.24. This
  supercedes any explicit-setup-deps settings in your stack.yaml
  and trusts the package's .cabal file to explicitly state all its
  dependencies.
• If system package installation fails, get-stack.sh will fail as well. Also
  shows warning suggesting to run apt-get update or similar, depending on the
  OS.
  (#2898)
• When stack ghci is 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 custom-setup and !include "..." in package.yaml.
• The script interpreter will now output error logging. In particular,
  this means it will output info about plan construction errors.
  (#2879)
• stack ghci now takes --flag and --ghc-options again (inadverently
  removed in 1.3.0).
  (#2986)
• stack exec now takes --rts-options which passes the given arguments inside of
  +RTS ... args .. -RTS to the executable. This works around stack itself consuming
  the RTS flags on Windows. (#2986)
• Upgraded http-client-tls version, which now offers support for the
  socks5:// and socks5h:// values in the http_proxy and https_proxy
  environment variables.

Bug fixes:

• Bump to hpack 0.16.0 to avoid character encoding issues when reading and
  writing on non-UTF8 systems.
• stack ghci will no longer ignore hsSourceDirs that contain ... (#2895)
• stack list-dependencies --license now works for wired-in-packages,
  like base. (#2871)
• stack setup now 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 --git now 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)

v1.3.2

See https://haskellstack.org for installation and upgrade instructions.

This is a small bug fix release.

Bug fixes:

• stack config set can now be used without a compiler installed
  #2852.
• get-stack.sh now installs correct binary on ARM for generic linux and raspbian,
  closing #2856.
• Correct the testing of whether a package database exists by checking
  for the package.cache file 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 new always treats templates as being UTF-8 encoding,
  ignoring locale settings on a local machine. See
  Yesod mailing list discussion

v1.3.0

See https://haskellstack.org for installation and upgrade instructions.

Release notes:

• 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.

Major changes:

• 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-ghc flag 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 setup line or use the --install-ghc
  flag.
  #2221

• stack ghci now 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-build flag 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 upgrade will
  now default to downloading a binary version of Stack from the most
  recent release, if one is available. See stack upgrade --help for
  more options.
  #1238

Behavior changes:

• Passing --resolver X with 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-dep setting, a warning is given to the user to provide one
  explicitly.

Other enhancements:

• stack haddock now supports --haddock-internal. See
  #2229
• Add support for system-ghc and install-ghc fields to stack config set command.
• Add ghc-build option to override autodetected GHC build to use (e.g. gmp4,
  tinfo6, nopie) on Linux.
• stack setup detects systems where gcc enables PIE by default (such as Ubuntu
  16.10 and Hardened Gentoo) and adjusts the GHC configure options accordingly.
  #2542
• Upload to Hackage with HTTP digest instead of HTTP basic.
• Make stack list-dependencies understand all of the stack dot options too.
• Add the ability for stack list-dependencies to list dependency licenses by
  passing the --license flag.
• Dump logs that contain warnings for any local non-dependency packages
  #2545
• Add the dump-logs config option and --dump-logs command line
  option to get full build output on the
  console. #426
• Add the --open option to "stack hpc report" command, causing the report to
  be opened in the browser.
• The stack config set command now accepts a --global flag 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 dot and stack list-dependencies now take targets and flags.
  #1919
• Deprecate stack setup --stack-setup-yaml for --setup-info-yaml based
  on discussion in #2647.
• The --main-is flag for GHCI now implies the TARGET, fixing
  #1845.
• stack ghci no longer takes all build options, as many weren't useful
  #2199
• --no-time-in-log option, to make verbose logs more diffable
  #2727
• --color option added to override auto-detection of ANSI support
  #2725
• Missing extra-deps are now warned about, adding a degree of typo detection
  #1521
• 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
  local-programs-path option in config.yaml.
  #1644
• Added option to add nix dependencies as nix GC roots
• Proper pid 1 (init) process for stack exec with Docker
• Dump build logs if they contain warnings.
  #2545
• Docker: redirect stdout of docker pull to 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
  when running nix-collect-garbage

Bug fixes:

• 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 sdist command.
  See #2549
• Never treat extra-dep local 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 sinkProcessStderrStdout which 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 report on 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-options to ghcjs. They were being
  provided as --ghc-options to Cabal, when it needs to be --ghcjs-options.
  #2714
• 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.yaml's docker run-args.
• stack setup --reinstall now behaves as expected.

v1.2.0

See https://haskellstack.org for installation and upgrade instructions.

Release notes:

• 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.

Major changes:

• Add stack hoogle command.
  #55
• Support for absolute file path in url field of setup-info or --ghc-bindist
• Add support for rendering GHCi scripts targeting different GHCi like
  applications
  #2457

Behavior changes:

• Remove stack ide start and stack ide load-targets commands.
  #2178
• Support .buildinfo files in stack ghci.
  #2242
• Support -ferror-spans syntax in GHC error messages.
• Avoid unpacking ghc to /tmp
  #996
• The Linux gmp4 GHC bindist is no longer considered a full-fledged GHC
  variant and can no longer be specified using the ghc-variant option,
  and instead is treated more like a slightly different platform.

Other enhancements:

• Use the store package for binary serialization of most caches.
• Only require minor version match for Docker stack exe.
  This way, we can make patch releases for version bounds and similar
  build issues without needing to upload new binaries for Docker.
• Stack/Nix: Passes the right ghc derivation as an argument to the shell.nix when a
  custom shell.nix is used
  See #2243
• Stack/Nix: Sets LD_LIBRARY_PATH so packages using C libs for Template Haskell can work
  (See e.g. this HaskellR issue)
• Parse CLI arguments and configuration files into less permissive types,
  improving error messages for bad inputs.
  #2267
• Add the ability to explictly specify a gcc executable.
  #593
• Nix: No longer uses LTS mirroring in nixpkgs. Gives to nix-shell a derivation
  like haskell.compiler.ghc801
  See #2259
• Perform some subprocesses during setup concurrently, slightly speeding up most
  commands. #2346
• stack setup no longer unpacks to the system temp dir on posix systems.
  #996
• stack setup detects libtinfo6 and ncurses6 and can download alternate GHC
  bindists #257
  #2302.
• stack setup detects Linux ARMv7 downloads appropriate GHC bindist
  #2103
• Custom stack binaries list dependency versions in output for --version.
  See #2222
  and #2450.
• Use a pretty printer to output dependency resolution errors.
  #1912
• Remove the --os flag
  #2227
• Add 'netbase' and 'ca-certificates' as dependency for .deb packages.
  #2293.
• Add stack ide targets command.
• Enhance debug logging with subprocess timings.
• Pretty-print YAML parse errors
  #2374
• Clarify confusing stack setup output
  #2314
• Delete Stack.Types multimodule to improve build times
  #2405
• Remove spurious newlines in build logs
  #2418
• Interpreter: Provide a way to hide implicit packages
  #1208
• Check executability in exec lookup
  #2489

Bug fixes:

• Fix cabal warning about use of a deprecated cabal flag
  #2350
• Support most executable extensions on Windows
  #2225
• Detect resolver change in stack solver
  #2252
• Fix a bug in docker image creation where the wrong base image was
  selected
  #2376
• Ignore special entries when unpacking tarballs
  #2361
• Fixes src directory pollution of style.css and highlight.js with GHC 8's
  haddock #2429
• Handle filepaths with spaces in stack ghci
  #2266
• Apply ghc-options to snapshot packages
  #2289
• stack sdist: Fix timestamp in tarball
  #2394
• Allow global Stack arguments with a script
  #2316
• Inconsistency between ToJSON and FromJSON instances of PackageLocation
  #2412
• Perform Unicode normalization on filepaths
  #1810
• Solver: always keep ghc wired-in as hard constraints
  #2453
• Support OpenBSD's tar where possible, require GNU tar for xz support
  #2283
• Fix using --coverage with Cabal-1.24
  #2424
• When marking exe installed, remove old version
  #2373
• Stop truncating all-cabal-hashes git repo
  #2175
• Handle non-ASCII filenames on Windows
  #2491
• Avoid using multiple versions of a package in script interpreter
  by passing package-id to ghc/runghc
  #1957
• Only pre-load compiler version when using nix integration
  #2459
• Solver: parse cabal errors also on Windows
  #2502
• Allow exec and ghci commands in interpreter mode.
  Scripts can now automatically open in the repl by using exec ghci
  instead of runghc in the shebang command.
  #2510
• Now consider a package to be dirty when an extra-source-file is changed.
  See #2040

v1.1.2

See haskellstack.org for installation and upgrade instructions.

Release notes:

• Official FreeBSD binaries are
  now available
  (#1253).

Major changes:

• 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.

Behavior changes:

• stack path --compiler was added in the last release, to yield a path to the
  compiler. Unfortunately, --compiler is 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 upgrade no longer pays attention to local stack.yaml files, just the
  global config and CLI options.
  #1392
• stack ghci now uses :add instead of :load, making it potentially work
  better with user scripts. See
  #1888

Other enhancements:

• Grab Cabal files via Git SHA to avoid regressions from Hackage revisions
  #2070
• Custom snapshots now support ghc-options.
• Package git repos are now re-used rather than re-cloned. See
  #1620
• DESTDIR is filtered from environment when installing GHC. See
  #1460
• stack haddock now supports --hadock-arguments. See
  #2144
• Signing: warn if GPG_TTY is not set as per man gpg-agent

Bug fixes:

• Now ignore project config when doing stack init or stack new. See
  #2110
• Packages specified by git repo can now have submodules. See
  #2133
• Fix of hackage index fetch retry. See re-opening of
  #1418
• HPack now picks up changes to filesystem other than package.yaml. See
  #2051
• "stack solver" no longer suggests --omit-packages. See
  #2031
• Fixed an issue with building Cabal's Setup.hs. See
  #1356
• Package dirtiness now pays attention to deleted files. See
  #1841
• stack ghci now uses extra-lib-dirs and extra-include-dirs. See
  #1656
• Relative paths outside of source dir added via qAddDependentFile are now
  checked for dirtiness. See
  #1982
• Signing: always use --with-fingerprints

• Added Ubuntu 16.04 LTS (xenial) Apt repo.
• No longer uploading new versions to Fedora 21 repo.

Behavior changes:

• Snapshot packages are no longer built with executable profiling. See
  #1179.
• stack init now ignores symlinks when searching for cabal files. It also now
  ignores any directory that begins with . (as well as dist dirs) - before
  it would only ignore .git, .stack-work, and dist.
• The stack executable is no longer built with -rtsopts. Before, when
  -rtsopts was enabled, stack would process +RTS options even when intended
  for some other program, such as when used with stack exec -- prog +RTS.
  See #2022.
• The stack path --ghc-paths option is deprecated and renamed to --programs.
  --compiler is added, which points directly at the compiler used in
  the current project. --compiler-bin points to the compiler's bin dir.
• For consistency with the $STACK_ROOT environment variable, the
  stack path --global-stack-root flag and the global-stack-root field
  in the output of stack path are being deprecated and replaced with the
  stack-root flag and output field.
  Additionally, the stack root can now be specified via the
  --stack-root command-line flag. See
  #1148.
• stack sig GPG-related sub-commands were removed (folded into upload and
  sdist)
• GPG signing of packages while uploading to Hackage is now the default. Use
  upload --no-signature if 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-1.2.3 will now build even if the snapshot has a different
  package version - it is treated as an extra-dep. stack build local-pkg-1.2.3
  is 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.
• Deprecate --local-bin-path instead --local-bin.
• stack image: allow absolute source paths for add.

Other enhancements:

• stack haddock --open [PACKAGE] opens the local haddocks in the browser.
• Fix too much rebuilding when enabling/disabling profiling flags.
• stack build pkg-1.0 will now build pkg-1.0 even if the snapshot specifies
  a different version (it introduces a temporary extra-dep)
• Experimental support for --split-objs added
  #1284.
• git packages with submodules are supported by passing the --recursive
  flag to git clone.
• When using hpack, only regenerate cabal files
  when hpack files change.
• hpack files can now be used in templates
• stack ghci now runs ghci as a separate process
  #1306
• Retry when downloading snapshots and package indices
• Many build options are configurable now in stack.yaml:

  build:
    library-profiling: true
    executable-profiling: true
    haddock: true
    haddock-deps: true
    copy-bins: true
    prefetch: true
    force-dirty: true
    keep-going: true
    test: true
    test-arguments:
      rerun-tests: true
      additional-args: ['-fprof']
      coverage: true
      no-run-tests: true
    bench: true
    benchmark-opts:
      benchmark-arguments: -O2
      no-run-benchmarks: true
    reconfigure: true
    cabal-verbose: true

• A number of URLs are now configurable, useful for firewalls. See
  #1794.
• Suggest causes when executables are missing.
• Allow --omit-packages even without --solver.
• Improve the generated stack.yaml.
• Improve ghci results after :load Main module collision with main file path.
• Only load the hackage index if necessary
  #1883, #1892.
• init: allow local packages to be deps of deps
  #1965.
• Always use full fingerprints from GPG
  #1952.
• Default to using gpg2 and fall back to gpg
  #1976.
• Add a flag for --verbosity silent.
• Add haddock --open flag #1396.

Bug fixes:

• Package tarballs would fail to unpack.
  #1884.
• Fixed errant warnings about missing modules, after deleted and removed from
  cabal file #921
  #1805.
• Now considers a package to dirty when the hpack file is changed
  #1819.
• Nix: cancelling a stack build now exits properly rather than dropping into a
  nix-shell #1778.
• allow-newer: true now causes --exact-configuration to be passed to Cabal.
  See #1579.
• stack solver no longer fails with InvalidRelFile for relative package
  paths including ... See
  #1954.
• Ignore emacs lock files when finding .cabal
  #1897.
• Use lenient UTF-8 decode for build output
  #1945.
• Clear index cache whenever index updated
  #1962.
• Fix: Building a container image drops a .stack-work dir in the current working
  (sub)directory
  #1975.
• Fix: Rebuilding when disabling profiling
  #2023.

v1.0.4.3

This is a hotfix for a bug that can cause the contents of your ~/.ssh directory to be deleted when using Docker integration and stack clean --full.

Bug fixes:

• Don't delete contents of ~/.ssh when using stack clean --full with Docker
  enabled #2000

v1.0.4

See haskellstack.org for installation and upgrade instructions.

Major changes:

• Some notable changes in stack init:
  • 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
  • Automatically omit a package (--omit-packages) when it is compiler
    incompatible or when there are packages with conflicting dependency
    requirements - #1674.
  • Some more changes for a better user experience. Please refer to
    the doc guide for details.
• Add support for hpack, alternative package description format
  #1679

Other enhancements:

• Docker: pass ~/.ssh and SSH auth socket into container, so that git repos
  work #1358.
• Docker: strip suffix from docker --version.
  #1653
• Docker: pass USER and PWD environment bariables into container.
• 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-user flag or allow-different-user
  option in the global config (/.stack/config.yaml).
  #471
• Added stack clean --full option for full working dir cleanup.
• YAML config: support Zip archives.
• Redownload build plan if parsing fails
  #1702.
• Give mustache templates access to a 'year' tag
  #1716.
• Have "stack ghci" warn about module name aliasing.
• Add "stack ghci --load-local-deps".
• Build Setup.hs with -rtsopts
  #1687.
• stack init accepts a list of directories.
• Add flag infos to DependencyPlanFailures (for better error output in case of
  flags) #713
• stack new --bare complains for overwrites, and add --force option
  #1597.

Bug fixes:

• Previously, stack ghci would fail with cannot satisfy -package-id when the
  implicit build step changes the package key of some dependency.
• Fix: Building with ghcjs: "ghc-pkg: Prelude.chr: bad argument: 2980338"
  #1665.
• Fix running test / bench with --profile / --trace.
• Fix: build progress counter is no longer visible
  #1685.
• Use "-RTS" w/ profiling to allow extra args
  #1772.
• Fix withUnpackedTarball7z to find name of srcDir after unpacking
  (fixes stack setup fails for ghcjs project on windows)
  #1774.
• Add space before auto-generated bench opts (makes profiling options work
  uniformly for applications and benchmark suites)
  #1771.
• Don't try to find plugin if it resembles flag.
• Setup.hs changes cause package dirtiness
  #1711.
• Send "stack templates" output to stdout
  #1792.
