New version released of stack, a build tool.

See README for installation and upgrade instructions.

Note: the binary tarballs’ contents have changed, and they now enclose their contents in a directory, and include documentation. If you have a script that should only extract the stack executable, use something like tar xzf stack-0.1.5.0-x86_64-osx.tar.gz --strip-components=1 stack-0.1.5.0-x86_64-osx/stack.

MinGHC installers have also been updated to include this version of stack (and will continue to be updated for future releases).

Major changes:

• On Windows, we now use a full MSYS2 installation in place of the previous PortableGit. This gives you access to the pacman package manager for more easily installing libraries.
• Support for custom GHC binary distributions #530
  • ghc-variant option in stack.yaml to specify the variant (also
    --ghc-variant command-line option)
  • setup-info in stack.yaml, to specify where to download custom binary
    distributions (also --ghc-bindist command-line option)
  • Note: On systems with libgmp4 (aka libgmp.so.3), such as CentOS 6, you
    may need to re-run stack setup due to the centos6 GHC bindist being
    treated like a variant
• A new --pvp-bounds flag to the sdist and upload commands allows automatic adding of PVP upper and/or lower bounds to your dependencies

Other enhancements:

• Adapt to upcoming Cabal installed package identifier format change #851
• stack setup takes a --stack-setup-yaml argument
• --file-watch is more discerning about which files to rebuild for #912
• stack path now supports --global-pkg-db and --ghc-package-path
• --reconfigure flag #914 #946
• Cached data is written with a checksum of its structure #889
• Fully removed --optimizations flag
• Added --cabal-verbose flag
• Added --file-watch-poll flag 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 -prof is given as a GHC option #1015
• Locking is now optional, and will be turned on by setting the STACK_LOCK environment variable to true #950
• Create default stack.yaml with documentation comments and commented out options #226
• Out of memory warning if Cabal exits with -9 #947

Bug fixes:

• Hacky workaround for optparse-applicative issue with stack exec --help #806
• Build executables for local extra deps #920
• copyFile can’t handle directories #942
• Support for spaces in Haddock interface files fpco/minghc#85
• Temporarily building against a “shadowing” local package? #992
• Fix Setup.exe name for —upgrade-cabal on Windows #1002
• Unlisted dependencies no longer trigger extraneous second build #838
