2023-05-13T11:12:28,138           For the time being, `setuptools` will still consider the given value (as a
2023-05-13T11:12:28,138           **transitional** measure), but please note that future releases of setuptools will
2023-05-13T11:12:28,138           follow strictly the standard.

2023-05-13T11:12:28,139           To prevent this warning, you can list `authors` under `dynamic` or alternatively
2023-05-13T11:12:28,139           remove the `[project]` table from your file and rely entirely on other means of
2023-05-13T11:12:28,139           configuration.

2023-05-13T11:12:28,139           By 2023-Oct-30, you need to update your project and remove deprecated calls
2023-05-13T11:12:28,139           or your builds will no longer be supported.
