 - 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.

+Version courante du pack distribué : **`26.2.0-alpha.205`**. Dans le workspace, la correction des colonnes CTM du Safe Block porte Another World en développement à **`0.0.0-alpha.54`** sans produire une nouvelle version du pack.
 
 L’alpha.205 exige une coque creuse de **3 × 3 × 3**, soit 26 Safe Blocks appartenant au même joueur, et actualise 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. Un ancien mur 3 × 3 ne s’active plus et doit être démonté puis reconstruit ; les comptes et soldes existants restent conservés.
