Drupal.org Ends Composer 1 Support on Packages Subdomain

Drupal.org announced on July 11, 2024, that it will end support for Composer 1 on Packages.Drupal.org. This move is part of efforts to prepare its infrastructure for providing automatic updates for Drupal and upgrading Drupal.org itself. New packages and releases will no longer be available for Composer 1 starting August 12, 2024, and full support will be dropped on October 1, 2024. This decision follows the broader trend in the Composer community, with Packagist.org also deprecating support for Composer 1.x. Currently, less than 1% of Drupal’s Composer traffic comes from Composer 1, making this transition timely and necessary for introducing automatic updates requiring Composer 2.

Drupal site administrators and developers are encouraged to prepare their sites for Composer 2, following the provided documentation for updating Drupal site codebases. Detailed status updates on the transition can be followed through issue #3201223: Deprecate composer 1. For further information and guidance on transitioning to Composer 2, users can visit the official announcement on Drupal.org at Ending Packages.Drupal.org support for Composer 1.
