PR Summary

• Configuration Adjustment in composer.json
  The developer has decided to remove a specific configuration in the composer.json file that previously permitted the use of plugins. This change might influence the way we manage dependencies and can possibly have effects on our project's functionality. The exact impact will largely depend on whether our project was using any plugins that were supported by this configuration.
