According to @Nils Adermann, Shutting down Packagist.org support for Composer 1.x. We need to upgrade to Composer 2.x before the February 1st, 2025, the read-only deadline. The upgrade is simple—most projects will work with 2.x without any issues. You can review the instructions on our original 2.0 blog post and notes on BC breaks.

To upgrade, use this command:

composer self-update --2
