Mojang has introduced a new content update for Minecraft, currently in public testing, featuring two cow variants: cold cows, which inhabit snowy biomes, and warm cows, found in desert landscapes. The update enhances desert biomes with new ambient sounds and allows players to create a desert atmosphere using dead bushes and sand blocks. Additionally, a new plant called the firefly bush emits glowing lights at night and can be cultivated with bone meal. Another bush variant can be found in various green biomes and can also be grown using bone meal. These features are available in the latest Java snapshot, with plans for inclusion in Bedrock beta versions. Mojang has shifted its content release strategy to smaller updates throughout the year instead of a single summer mega-update.
