The cleaned-up Xaraya modules have been moved to separate repositories in the new https://github.com/xaraya-modules organization, and submitted as individual packages of type 'xaraya-module' at https://packagist.org/?type=xaraya-module
You can also use the dedicated package repository available at https://xaraya-modules.github.io/composer/
The original modules are available as branches in the old https://github.com/xaraya/modules repository
