in version 1.5.1 i fixed a critical bug. now i am fully confident in the mod's stability, so this version marks the transition from beta to release.

fixed

memory leak: fixed a memory leak in the auto-refill system. the mod was not clearing the cache for disconnected players, causing RAM usage to slowly increase over time on servers.
