Haskell Stack 3.7.1 ڈاؤن لوڈ

See https://haskellstack.org/ for installation and upgrade instructions.
Changes since v3.5.1:
Other enhancements:
- Bump to Hpack 0.38.1.
- The --extra-dep option of Stack's script command now accepts a YAML value specifying any immutable extra-dep. Previously only an extra-dep in the package index that could be specified by a YAML string (for example, acme-missiles-0.3@rev:0) was accepted.
Bug fixes:
- stack script --package <pkg-name> now uses GHC's -package-id option to expose the installed package, rather than GHC's -package option. For packages with public sub-libraries, -package <pkg> can expose an installed package other than one listed by ghc-pkg list <pkg>.
- Work around ghc-pkg bug where, on Windows only, it cannot register a package into a package database that is also listed in the GHC_PACKAGE_PATH environment variable. In previous versions of Stack, this affected stack script when copying a pre-compiled package from another package database.
- On Windows, when decompressing, and extracting tools, from archive files, Stack uses the system temporary directory, rather than the root of the destination drive, if the former is on the destination drive.
