 - Depuis `26.2.0-alpha.6`, le pack et les modules ont des versions indépendantes. I Like To Move It et Only Fun deviennent les cinquième et sixième modules actifs dans l'alpha 46.
 - Les versions ci-dessous ont été reconstituées à partir des JAR archivés, des packs locaux et du code source actuel. Les dates n'étant pas enregistrées de manière fiable, elles ne sont pas inventées.
 
+## En développement — coffre-fort à soldes illimités
+
+Module modifié : **Another World `0.0.0-alpha.55`**. Le pack distribué reste en **`26.2.0-alpha.206`** jusqu’à la prochaine release.
+
+- remplace les 27 piles du coffre-fort par trois soldes 64 bits séparés pour les rubis, saphirs et émeraudes ;
+- migre automatiquement chaque pile existante vers son solde correspondant dans `safe_vaults` v4, sans changer les IDs ni exiger de nouveau monde ;
+- synchronise les soldes 64 bits avec l’interface et les affiche sous forme compacte au-delà de 999 ;
+- conserve l’accès du Shop aux monnaies stockées et borne son API historique 32 bits sans limiter le solde réel ;
+- crédite directement les 20 % pillés dans le coffre-fort de l’attaquant afin d’éviter de générer un nombre non borné d’objets ;
+- porte Another World en donnée v5 et protocole réseau 2 ; Packwiz sera actualisé lors de la prochaine version distribuée.

 ## `26.2.0-alpha.206`
 
 Module modifié : **Another World `0.0.0-alpha.54`**. Les neuf autres modules conservent leur version issue de l’alpha.205.

 Version courante du pack distribué : **`26.2.0-alpha.206`**. Cette release distribue Another World **`0.0.0-alpha.54`** avec les colonnes A et C corrigées sur la façade et le dos du coffre-fort.
 
+Dans le workspace en développement, Another World **`0.0.0-alpha.55`** 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.
+
 L’alpha.206 exige une coque creuse de **3 × 3 × 3**, soit 26 Safe Blocks appartenant au même joueur, et conserve JEI en **`30.27.0.189`**. Le centre est libre et peut contenir un bloc caché. Les quatre images 48×48 se répartissent sur les faces extérieures du cube : façade, dessus, dessous et côtés/arrière. Les colonnes extrêmes de la façade et du dos sont désormais orientées correctement. Un ancien mur 3 × 3 ne s’active plus et doit être démonté puis reconstruit ; les comptes et soldes existants restent conservés.
 
 L’alpha.204 finalise le Safe Block vertical et actualise JEI en **`30.27.0.188`** : sa texture individuelle 16×16 est chargée avant formation, les structures incomplètes 3 × 1 sont refusées et le CTM 48×48 exige les neuf blocs. L’interface monétaire affiche désormais correctement l’émeraude et place l’inventaire étendu sous les trois lignes de monnaie.
