The release is essentially a hardened distribution of Drupal, complemented with technical support and network service offerings. Code named Carbon for now, the package includes a select set of community contributed modules alongside the Drupal core. Acquia has taken the task of pre-testing, reviewing, and comparing all community contributed modules to offer a set of the most relevant and reliable contributions. Site administrators are notified of updates to Carbon modules through the network, code named Spokes. The system differentiates between feature, bug fix, and security updates, and informs users of compatibility issues or other dependencies amongst different modules.Essentially, Acquia is providing users with a service that it can monetize. That service is support, and it is a great business opportunity that is likely to succeed as the increase of demand in open source software grows. If you would like to explore Acquia's projects and support for the Drupal project, check out their website.Access to the Beta is currently open to only the first 100 TechCrunch registrants -- expect you missed that boat already -- or to anyone who requests entry in person at Drupalcon Szeged. But fear not, they are offering new invites every week - so be sure to get on the list to receive yours. Come back and let us know how the beta works.
