I will update this list regularly to let you know what's going on for the Drupal 8 Multilingual Initiative. This initiative is for making big improvements in multilingual support for Drupal 8 including cleaning up inconsistencies and poor designs in the architecture, making localization process more user-friendly, allowing for non-English source strings, and pulling in relevant functionality from contributed modules such as i18n. Please help out!
