See [https://haskellstack.org/](https://haskellstack.org/) for installation and upgrade instructions.

Release notes:

- Further to the release notes for Stack 2.3.1, the `-static` suffix has been removed from the statically linked Linux/x86\_64 binaries.
- The binaries for Linux/Aarch64 are now statically linked.
- Binaries are now provided for macOS/AArch64.

**Changes since v2.11.1:**

Behavior changes:

- Build artefacts are placed in `.stack-work/dist/<platform>/<GHC_version>` (hashed to a shorter path on Windows), rather than `.stack-work/dist/<platform>/<Cabal_version>`. This allows build artifacts to be distinguished by GHC version.
- By default, the `stack build` progress bar is capped to a length equal to the terminal width.
- When building GHC from source, Stack no longer uses Hadrian’s deprecated `--configure` \ `-c` flag and, instead, seeks to run GHC’s Python `boot` and sh `configure` scripts, and ensure that the `happy` and `alex` executables are on the PATH.
- When auto-detecting `--ghc-build` on Linux, the `musl` GHC build only is considered a possible GHC build if `libc.musl-x86_64.so.1` is found in `\lib` or `\lib64`.
- No longer supports Cabal versions older than `1.24.0.0`. This means projects using snapshots earlier than `lts-7.0` or `nightly-2016-05-26` will no longer build.
- When unregistering many packages in a single step, Stack can now do that efficiently. Stack no longer uses GHC-supplied `ghc-pkg unregister` (which is, currently, slower).
- `stack hpc report`, `stack list`, `stack templates` and `stack uninstall` output their information to the standard output stream rather than to the standard error stream. Logging is still to the standard error stream.
- `stack upgrade` no longer assumes that binary upgrade is not supported on a AArch64 machine architecture.

Other enhancements:

- Bump to Hpack 0.36.0.
- Depend on `pantry-0.9.2`, for support for long filenames and directory names in archives created by `git archive`.
- Avoid the duplicate resolving of usage files when parsing `*.hi` files into a set of modules and a collection of resolved usage files. See [#6123](https://github.com/commercialhaskell/stack/pull/6123).
- Add composable component type flags `--exes`, `--tests` and `--benchmarks` to Stack’s `ide targets` command, to list only those components.
- `stack --verbose` excludes lengthy information about build plan construction in the debug output by default. The new `stack --[no-]plan-in-log` flag enables or disables the inclusion of the information in the debug output.
- In YAML configuration files, the `casa` key is introduced, which takes precedence over the existing `casa-repo-prefix` key. The latter is deprecated. The new key also allows Stack’s use of a Casa (content-addressable storage archive) server to be disabled and the maximum number of keys per request to be configured. The defaults are unchanged.
- Add option `--progress-bar=<format>` to Stack’s `build` command to configure the format of the progress bar, where `<format>` is one of `none`, `count-only` (only the package count), `capped` (capped to a length equal to the terminal width) and `full` (the previous format).

Bug fixes:

- Restore `stack sdist --pvp-bounds lower` (broken with Stack 2.9.1).
- Restore building of Stack with Cabal flag `disable-git-info` (broken with Stack 2.11.1).
- With `stack hoogle`, avoid the message `Minimum version is hoogle-5.0. Found acceptable hoogle-<x.y.z> in your index, requiring its installation.` when a `hoogle` executable has already been found on the `PATH`.
- Stack’s sanity check on a selected GHC now passes GHC flag `-hide-all-packages`, stopping GHC from looking for a package environment in default locations.
- Restore Stack script files without extensions (broken with Stack 2.11.1).
- Restore message suffix `due to warnings` with `dump-logs: warning` (broken with Stack 2.11.1).
- On Windows, the `local-programs-path` directory can now be on a different drive to the system temporary directory and MSYS2 will still be installed.

Thank you

Can now be built from latest Stackage Nightly btw.
