During the development of the console the project have been in syncronization with the development branch of Drupal 8.
This make sense at the begining of the project when Drupal 8 was in Alpha state.
Since DrupalCon Amsterdam Drupal Beta 01 version has been released for testing and feedback and after some discussion with David Flores the other co-maintainer of the project we decide to keep the project in syncronization with Drupal Beta releases.
The current release of Drupal 8 is Beta 02.
Related to code changes this was an easy step just an update the composer.json file.
Make easier for anyone trying to test the console project, since they do not need to keep in sync with every single release and use a bleeding edge version of Drupal 8.
