Rebalances stack sizes throughout the game. Player inventories, chests, barrels, ender chests, shulker boxes, and minecart chests hold effectively unlimited quantities of a single item, while automation-sensitive containers like hoppers, dispensers, droppers, furnaces, brewing stands, and crafters keep vanilla's stack size of 64 so redstone contraptions, sorters, and comparator-based systems keep working exactly as they did before.
- Unlimited storage stacking: player inventory, chests, barrels, ender chests, shulker boxes, and minecart chests hold up to roughly 21.4 million of a single non-durability item per slot
- Vanilla automation containers unchanged: hoppers, dispensers, droppers, furnaces, brewing stands, and crafters are explicitly kept at the vanilla 64-stack cap so item transfer rates, sorting, and comparator logic aren't affected
- Durability and container items stack normally: tools, weapons and armor (anything with a max-damage component) keep vanilla stacking, and so do bundles and shulker boxes, whose contents live on the stack itself. Two in one stack would share one set of contents
- Bundles rebalanced by type, not weight: bundles hold up to 9 distinct item types with unlimited quantity per type, instead of vanilla's weight-based capacity; the bundle's fullness bar reflects how many of the 9 type slots are used
- Comparator signal fix: containers with unlimited stack sizes still report a non-zero redstone comparator signal when they contain any items, instead of the 0 vanilla's formula would otherwise produce; capped containers keep the full 0-15 signal range
- Compact stack count display: on clients running Pandorical, large stack counts render as abbreviated labels (e.g.
12k,3.4m,1b) with an exact-count tooltip; that presentation now lives in Pandorical, so stackz itself ships no client code. Vanilla clients still handle oversized counts correctly, they just draw the raw number - Uncapped save/load: item stack codecs are patched so large stacks serialize and deserialize correctly instead of being clamped
