I just presented a fully up to date version of my multilingual Drupal 8 talk this week at DrupalCon Prague to a packed audience of people sitting even on the floor to learn what is coming in Drupal 8. To quote one of the feedback posts I got: Great presentation of all the beautiful work that has been done for making multilanguage easier and more flexible in Drupal 8. Can't wait to be able to use it on production! Watch this talk to figure out why!
And once again thanks to all the (almost) 900 contributors who made this happen. You rock so much! It is a pleasure working with you!
