Error: the `add-path` command is deprecated and will be disabled on November 16th

When using your action, I get following error/warning:

Setting up ghc-8.10.1 (8.10.1-17~18.04) ...
  Processing triggers for libc-bin (2.27-3ubuntu1.3) ...
  Error: The `add-path` command is deprecated and will be disabled on November 16th. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2020-10-01-github-actions-deprecating-set-env-and-add-path-commands/

FYI: these errors are gone in 1.1.3. Example:

    - name: Setup Haskell toolchain
      uses: actions/setup-haskell@v1.1.3

There are two different things going on here.

• Users on mac or ubuntu should update to the latest version v1.1.3 or use the sliding tag v1 to ensure they have the latest fixes for this issue.
• Windows users: We've identified a bug where ghc on install wipes the environment variables in the session, causing us to fallback to the old add-path pattern because the environment variable flow requires the GITHUB_PATH variable to be set

It appears the ghc choco repo automatically runs the old command, I filed an issue to get that fixed Mistuke/GhcChoco#10

hi, builds now fails with:

Error: Unable to process command '::add-path::C:\ProgramData\chocolatey\lib\ghc.8.10.1\tools\ghc-8.10.1\bin' successfully.
  Error: The `add-path` command is disabled. Please upgrade to using Environment Files or opt into unsecure command execution by setting the `ACTIONS_ALLOW_UNSECURE_COMMANDS` environment variable to `true`.

@thboop what can we do on the Windows in the meantime, is there a way to go around this?
I am using "v1" and it works ok on ubuntu/macos, but as you said, build on Windows fails.

[thboop]

@Martinsos please see the PR here for mitigation, you should be able to opt into enabling these commands until a fix for this action is in place.

We are aiming to get a new version of setup-haskell published in the next day or so to resolve the issue on windows.

This has been fixed in version v1.1.4 and the v1 tag has been updated! Thank you all for your patience.
