This document discusses Drupal 8's new configuration management system which stores things like content types, menus, views, taxonomy terms, and settings in code-managed configuration files rather than the database. It notes benefits like eliminating 50 database tables, reduced need for features and strongarm modules, and translatability. Configuration can be stored and versioned in files under CVS/Git or in MongoDB. The document also covers how the configuration system interacts with the Features module and provides new Drush commands for exporting, importing, editing, getting, listing, and pulling configuration.
