In his State of Drupal presentation at DrupalCon New Orleans in May 2016, Dries identified Layouts as a core strategic initiative for Drupal 8, and work is well under way!

This session will discuss:

the existing layout solutions in contrib
the proposed solutions for core
what progress has been made so far
what decisions are left to be made
how you can help!
Those attending should have experience with layout concepts and ideas or opinions about how layouts should be handled in Drupal.

Working knowledge of either Panels/Panelizer or Display Suite is useful but not necessary
