Items Stack

A major overhaul of the mod’s stack-size system, configuration, and management workflow.

Major changes

• Reworked the internal stack-size override system
• Rebuilt the configuration format into a simpler single-rule list
• Added in-game commands for managing stack-size rules
• Added support for resetting configured items and tags back to their default stack size
• Added save and reload commands for explicitly controlling when config changes are written to disk
• Added filtering and paging support for listing configured rules
• Improved handling of very large stack sizes
• Improved rendering of large stack counts
• Explicit per-stack MAX_STACK_SIZE component changes are now respected
• Normal Minecraft stacking behavior for differing components and damage values is preserved
• Improved compatibility when the mod is installed server-side without requiring it on the client

Config changes

The old multi-list configuration format has been replaced by a single overrides list.

Rules now use the format:

item_or_tag=value

Exact item rules take priority over tag rules. Among rules of the same type, later rules override earlier ones.

The special value default can be used to force an item or tag back to its normal Minecraft stack size.

Commands

Added /itemsstack commands for:

• Setting rules
• Removing rules
• Resetting rules to default
• Clearing rules
• Listing configured rules
• Saving the config
• Reloading the config
• Viewing command help

Config changes are applied immediately. /itemsstack save writes the current configuration to disk, while /itemsstack reload discards unsaved changes and reloads the saved configuration.
