stack v1.0.0 Release Notes

  • 🚀 Release notes:

    • We're calling this version 1.0.0 in preparation for Stackage LTS 4. Note, however, that this does not mean the code's API will be stable as this is primarily an end-user tool.

    ✨ Enhancements:

    • ➕ Added flag --profile flag: passed with stack build, it will enable profiling, and for --bench and --test it will generate a profiling report by passing +RTS -p to the executable(s). Great for using like stack build --bench --profile (remember that enabling profile will slow down your benchmarks by >4x). Run stack build --bench again to disable the profiling and get proper speeds
    • ➕ Added flag --trace flag: just like --profile, it enables profiling, but instead of generating a report for --bench and --test, prints out a stack trace on exception. Great for using like stack build --test --trace
    • 💻 Nix: all options can be overridden on command line #1483
    • 🏗 Nix: build environments (shells) are now pure by default.
