@github-actions github-actions released this 19 Sep 09:54

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

Changes since v2.7.5:

Behavior changes:

  • stack build --coverage will generate a unified coverage report, even if there is only one *.tix file, in case a package has tested the library of another package that has not tested its own library. See #5713
  • stack --verbose no longer includes the lengthy raw snapshot layer (rsl) in the debug output by default. The new stack --[no-]rsl-in-log flag enables or disables the inclusion of the rsl in the debug output.

Other enhancements:

  • Bump to Hpack 0.35.0.
  • On Windows, the installer now sets DisplayVersion in the registry, enabling tools like winget to properly read the version number.
  • Adds flag --script-no-run-compile (disabled by default) that uses the --no-run option with stack script (and forces the --compile option). This enables a command like stack --script-no-run-compile Script.hs to behave like stack script <arguments> --no-run --compile -- Script.hs but without having to list all the <arguments> in the Stack interpreter options comment in Script.hs on the command line. That may help test that scripts compile in CI (continuous integration). See #5755
  • Fuller help is provided at the command line if a subcommand is missing (for example, stack ls now yields the equivalent of stack ls --help). See #809
  • Add build option --cabal-verbosity=VERBOSITY to specify the Cabal verbosity level (the option accepts Cabal's numerical and extended syntax). See #1369
  • Add the possibility of a sh script to customise fully GHC installation. See #5585
  • tools subcommand added to stack ls, to list stack's installed tools.
  • stack uninstall shows how to uninstall Stack.
  • --ghc-variant accepts int-native as a variant.

Bug fixes:

  • Fix stack clean --full, so that the files to be deleted are not in use. See #5714
  • Fix an inconsistency in the pretty formatting of the output of stack build --coverage
  • Fix repeated warning about missing parameters when using stack new
  • Include pantry-0.5.6: Remove operational and mirror keys from bootstrap key set. See #53
  • Pass any CPP options specified via cpp-options: in the Cabal file to GHCi using GHC's -optP flag. See #5608
  • On Unix-like operating systems, respect the with-gcc option when installing GHC. See #5609
  • Fixed logic in get_isa() in get-stack.sh to exclude systems that don't have x86 in their uname -m output. See #5792.
  • Fixed output of stack ls snapshots local on Windows, to behave like that on Unix-like operating systems.
  • Fix non-deterministic test failures when executing a test suite for a multi-project repository with parallelism enabled. See #5024
