As previously announced, the npm registry now requires TLS 1.2 or higher for all requests, including package installation.
The Codes of Conduct API preview, which was accessible with the
scarlet-witch-preview header, is being deprecated.
On December 6th, 2021, the fields behind this API preview will no longer be accessible. We recommend using the Get community profile metrics endpoint to retrieve information about a repository's code of conduct.
Email notifications will be sent to active users of the API preview throughout the deprecation period.
If you have any questions, please contact GitHub Support.
