New version released of Stack, a build tool.

See README for installation and upgrade instructions.

There are now Windows installers available: download them here. In addition, new Fedora 23 packages are available here.

Note that, starting with v0.1.8.0, releases of Stack will always have an even-numbered second-to-last version component. Odd second-to-last version components are reserved for unstable builds.

Major changes:

• GHCJS can now be used with stackage snapshots via the new compiler field.
• Docker integration works with non-FP Complete generated images
  #531

Other enhancements:

• Added an allow-newer config option
  #922
  #770
• When a Hackage revision invalidates a build plan in a snapshot, trust the
  snapshot #770
• Added a stack config set resolver RESOLVER command. Part of work on
  #115
• stack setup can now install GHCJS on windows. See
  #1145 and
  #749
• stack hpc report command added, which generates reports for HPC tix files
• stack ghci now accepts all the flags accepted by stack build. See
  #1186
• stack ghci builds the project before launching GHCi. If the build fails,
  optimistically launch GHCi anyway. Use stack ghci --no-build option to
  disable #1065
• stack ghci now detects and warns about various circumstances where it is
  liable to fail. See
  #1270
• Added require-docker-version configuration option
• Packages will now usually be built along with their tests and benchmarks. See
  #1166
• Relative local-bin-path paths will be relative to the project’s root
  directory, not the current working directory.
  #1340
• stack clean now takes an optional [PACKAGE] argument for use in
  multi-package projects. See
  #583
• Ignore cabal_macros.h as a dependency
  #1195
• Pad timestamps and show local time in —verbose output
  #1226
• GHCi: Import all modules after loading them

• Add subcommand aliases: repl for ghci, and runhaskell for runghc
  #1241
• Add typo recommendations for unknown package identifiers
  #158
• Add stack path --local-hpc-root option
• Overhaul dependencies’ haddocks copying
  #1231
• Support for extra-package-dbs in ‘stack ghci’
  #1229

  subdirectories or outside the project root
  #1259
