Data Pack News in Minecraft 26.1 (Pack Version 101.1)

Minecraft 26.1 updates the data pack version to 101.1, introducing world clocks with configurable tick rates, pause/resume commands, and time markers. Villager trades are now data-driven via new JSON registries for individual trade offerings and trade sets. The update also overhauls recipes with unified result formats, adds new loot table predicates and number providers, makes mob sound variants data-driven for cats, pigs, chickens, and cows, introduces new block/item tags for dirt, vegetation, and fluid behavior, and reorganizes dimension data storage. Additional changes include new environment attributes for lighting colors, renamed world generation features, updated entity data, new particles, and text component improvements.
