From Aloha to CKEditor

Recently Dries announced that Drupal 8 will not use Aloha, but ckeditor:

Since that announcement, CKEditor has caught up, and now offers feature parity to Aloha Editor when it comes to our needs. Frederico Knabben, creator of CKEditor, has reached out to offer whatever support he can to make CKEditor and Drupal work together better. They already prototyped a convincing alternative to Aloha Editor's killer "Blocks" system (which is an excellent match for Drupal's need to manage content within text content in a structured manner). In addition to that, we found that CKEditor is more mature in terms of APIs, documentation, and ecosystem around the project. Hence, after days of research and weeks of further discussion, the consensus is that CKEditor is now our best choice.
