commercialhaskell/stack v2.7.1 on GitHub

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

Changes since v2.5.1.1:

Behavior changes:

stack repl now always warns about GHCi problems with loading multiple
packages. It also sets now proper working directory when invoked with
one package. See
#5421
custom-setup dependencies are now properly initialized for stack dist.
This makes explicit-setup-deps no longer required and that option was
removed. See
#4006

Other enhancements:

Nix integration now passes ghcVersion (in addition to existing ghc) to
shell-file as an identifier that can be looked up in a compiler attribute set.
Nix integration now allows Nix integration if the user is ready in nix-shell.
This gets rid of "In Nix shell but reExecL is False" error.
stack list is a new command to list package versions in a snapshot.
See #5431
Consider GHC 9.0 a tested compiler and remove warnings.
custom-preprocessor-extensions is a new configuration option for allowing
stack to be aware of any custom preprocessors you have added to Setup.hs.
See #3491
Added --candidate flag to upload command to upload a package candidate
rather than publishing the package.
Error output using --no-interleaved-output no longer prepends indentating
whitespace. This allows emacs compilation-mode and vim quickfix to locate
and track errors. See
#5523

Bug fixes:

stack new now suppports branches other than master as default for
GitHub repositories. See
#5422
Ignore all errors from hi-file-parser. See
#5445 and
#5486.
Support basic auth in package-indices. See
#5509.
Add support for parsing .hi. files from GHC 8.10 and 9.0. See
hi-file-parser#2.
