The Drupal 8 configuration management system replaces the variable system we all know and love. And it does much more than just that. Views, blocks, date formats, and the system module list are all stored in configuration.
We are nearing the finish line!!! But we have some tricky tasks to complete. Unfortuantely many of the tasks left are complex and so this sprint is not suitable for complete beginners. But if you want to ramp up before you get to Szeged visit http://drupal8cmi.org to see what we still need to do and meet the team in IRC on #drupal-cmi where we have regular bi-weekly meetings.
