Dries Buytaert, the Drupal project lead, will facilitate a Drupal 8 retrospective discussion at DrupalCon Barcelona.

After more than four years of development, Drupal 8 is quickly approaching its first release candidate. This will be a landmark release with myriad new features and improvements. In addition to many technical changes, we innovated on how we collaborate on the Drupal project itself as well as on drupal.org. We involved more than three times the contributors of Drupal 7. Now it's time to take stock of the cycle, of where we've been and how it went, so we can keep improving. We'd like your input on the following:

1. What worked well? What were the highlights of the Drupal 8 cycle?
2. What didn't work well? What are lessons we've learned for upcoming releases or for the community as a whole?
3. What concrete improvements can we make for future releases (both minor and major)? We welcome suggestions around teams, tools, or processes.

Please submit your answers online. Dries will gather the community's responses and use them as the basis for the open discussion at DrupalCon Barcelona.
