Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipe/recipe.yaml) and found some lint.

Here's what I've got...

For recipe/recipe.yaml:

• ❌ You are setting c_stdlib_version on osx below the current global baseline in conda-forge (11.0).

• ❌ In conda-forge.yml: $.github_actions = {'self_hosted': True, 'triggers': ['push', 'pull_request']}.

  {'self_hosted': True, 'triggers': ['push', 'pull_request']} is not valid under any of the given schemas

  Schema

  {
    "anyOf": [
      {
        "$ref": "#/$defs/GithubActionsConfig"
      },
      {
        "type": "null"
      }
    ]
  }

forge linter is failing. other things are mostly passing. I am not sure how to move forward..

Linter fixes and fixes for the cirunner upstream CI break (see conda-forge/admin-requests#1982) are part of #262

That PR is nearly finished running the final Windows builder. Once passing, rebasing off that should fix this as well.

ok, let's merge the other one (for the release), and we can revisit this one and see if there are extra actions required.

I see that this PR has conflicts, and I'm the only committer. I'm going to close this PR and will make another one as appropriate. You should expect to wait at least a few hours, or possibly much longer, for a new PR.
