The stack upgrade command


stack upgrade [--binary-only] [--binary-platform ARG] [--force-download]
              [--binary-version ARG] [--github-org ARG] [--github-repo ARG]


stack upgrade [--source-only] [--git] [--git-repo ARG] [--git-branch ARG]

stack upgrade will get a new version of Stack, either from an existing binary distribution (pass the --binary-only flag, the default) or from compiling source code (pass the --source-only flag). The --binary-only and --source-only flags are alternatives.

When compiling from source code, by default:

  • Stack will obtain the source code for the most recent version in the package index (eg Hackage). Pass the flag --git to specify the most recent version from the master branch of Stack's repository.
