@hirak any plans to merge this PR. We are getting a lot of mails from GitHub complaining about the access_token on parameters.

On February 12th, 2020 at 08:03 (UTC) your personal access token (jenkins) using Composer/1.9.3 (Linux; 4.14.146-93.123.amzn1.x86_64; PHP 7.2.22) was used as part of a query parameter to access an endpoint through the GitHub API:

https://api.github.com/repositories/xxxx/zipball/xxxx

Please use the Authorization HTTP header instead, as using the access_token query parameter is deprecated and will be removed July 1st, 2020.

Composer already made a fix for that on version 1.9.3
