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 #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
