# 1.3.0 - Minecraft 26.3 support - Minecraft 26.2 support - Minecraft 26.1.2 support (Java 25). - Modernize package and maven group: Java package `net.rpg_foundation.structure_pool` (was `net.fabric_extras.structure_pool`), maven group `net.rpg_foundation` (was `net.foundation`); mod id and data unchanged - **Spawn limits are now enforced for elements reached through a pool's fallback pool.** They were silently uncapped before. **This is seed-visible**: filtering an element out of a candidate list changes what `Util.shuffle` returns, so an affected structure generates differently for the same seed. Only structures whose placement reaches an injected element via a fallback pool are affected. - No longer ships an access widener (Fabric) / access transformer (NeoForge) — one fewer thing to conflict with. - One fewer mixin: `StructureTemplatePool` is no longer mixed into at all (injected elements are now identified by instance identity), and all mixin-owned members are `@Unique`. - `injectIntoStructurePool` is idempotent per pool instance: injecting the same structure into the same pool twice no longer doubles its weight, and warns instead. - Injecting now invalidates the pool's memoised `maxSize`. - The "structure pool not found" message goes to the mod logger instead of `System.err`, so a mistyped pool id in a config is visible in a filtered log.
