Les packs Modrinth, Prism et Packwiz sont mis à jour sans exiger de nouveau monde ni réinitialiser les sauvegardes.
 
 L’alpha.207 rend le stockage du coffre-fort pratiquement illimité : rubis, saphirs et émeraudes utilisent chacun un solde 64 bits. Les 27 anciennes piles sont additionnées automatiquement lors du chargement, le Shop continue de consommer directement ces soldes et les 20 % pillés sont crédités dans le coffre-fort de l’attaquant sans créer des millions d’entités ou de piles d’objets.
