CobbleStacker v1.1.0 - Changelog

Spawner-Only Mob Stacking
Mobs will now only stack if they were spawned by a mob spawner. Natural mobs (ones that spawn in caves, at night, etc.) will behave completely vanilla and
won't be stacked together. This makes gameplay feel much more natural while still keeping your spawner farms optimized and lag-free.

This is enabled by default. If you want the old behavior (stack all mobs), set "mobOnlySpawnerStack": false in the config.

Item Nametag Visibility Fix
Fixed a bug where setting "itemNametagAlwaysVisible": false would make item stack nametags completely invisible instead of showing them when you're nearby (like mob nametags do). Now when set to false, item nametags will appear when you're within range of the item stack and disappear when you walk away
