There are two great sessions accepted for DrupalCon Prague involved with multilingual features that you will love!
I'll talk about all the multilingual site tools in Drupal 8 that were added and improved thanks to over 800 (yes eight hundred) collaborators who keep working tirelessly so we have a fundamentally multilingual system in Drupal 8.
While Drupal 8 makes almost anything multilingual, overarching workflows and full multilingual site management tools are not included. That is where the Translation Management Tools session comes in. Come to Michael Schmid's and Christophe Galli's session to learn about the missing workflow and integration layer that is there for you in contrib.
