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

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ License is not an SPDX identifier (or a custom LicenseRef) nor an SPDX license expression.

Documentation on acceptable licenses can be found here.

• ℹ️ In conda-forge.yml: $.compiler_stack = comp7.

  'Compiler Stack' is deprecated.
  Compiler stack environment variable. This is used to specify the compiler
  stack to use for builds. Deprecated.

  compiler_stack: comp7

  Schema

  {
    "anyOf": [
      {
        "type": "string"
      },
      {
        "type": "null"
      }
    ],
    "default": "comp7",
    "deprecated": true,
    "title": "Compiler Stack"
  }
