Earlier this year, for DrupalCon San Francisco, we introduced the new concept of the Core developer summit, which reaches back to the original Drupal developer meetups allowing for planning, problem solving and coding for Drupal core developers. It makes it possible to get together in one space to plan ahead and solve problems at hand.
We always keep looking at ways to improve our processes, and for the summit announced for Drupalcon Copenhagen, we’ve seen less interest in presenting improvement suggestions and more on looking at how Drupal 7 can be brought forward. So our plan for the Core developer summit in Copenhagen is twofold: provide a place to plan ahead and hammer some outstanding issues for Drupal 7 at the same time.
