Like the alphas beforehand, if you want to use with Stack:

[1] Either (a) upgrade to the master branch version of Stack (can be used only if you are not using GHCup to manage versions of Stack): stack upgrade --source-only --git; or (b) test the first release candidate for Stack 2.15.7.

[2A] If you are not using GHCup to manage versions of GHC, augment Stack’s default setup-info dictionary in a configuration file (needed only until Stack has fetched the compiler once). For example, on Windows:

setup-info:
  ghc:
    windows64:
      9.10.0.20240426:
        url: https://downloads.haskell.org/ghc/9.10.1-rc1/ghc-9.10.0.20240426-x86_64-unknown-mingw32.tar.xz
        # Can be extended with SHA protections etc: see https://docs.haskellstack.org/en/stable/yaml_configuration/#setup-info

[2B] If you are using GHCup to manage versions of GHC, you can augment ~/.ghcup/config.yaml. For example, either:

(1)

url-source:
  - StackSetupURL
  - setup-info:
      ghc:
        windows:
          9.10.0.20240426:
            url: https://downloads.haskell.org/ghc/9.10.1-rc1/ghc-9.10.0.20240426-x86_64-unknown-mingw32.tar.xz
            # Can be extended with SHA protections etc: see https://docs.haskellstack.org

or, alternatively:

(2)

url-source:
  - StackSetupURL 
  - https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.8.yaml

[3] Specify the compiler in a Stack configuration file (eg stack.yaml):

compiler: ghc-9.10.0.20240426
