Minecraft Java 1.21.5 update patch notes: Animal variants, spawn egg revamp, ambient blocks, QoL changes, and more

After nearly three months of The Garden Awakens, Minecraft is back with another exciting game drop for fans to enjoy, titled Spring to Life. This update breathes fresh life into many Overworld biomes that have started to feel dull due to a lack of new features.

The Minecraft 1.21.5 update introduces two new variants for pigs, chickens, and cows, depending on whether they spawn in a warm or cold biome. As for the original variants, they are now referred to as temperate animals. Apart from animal variants, Mojang has added plenty of new blocks to enhance the aesthetics and ambiance of various Overworld biomes, such as plains, deserts, rivers, swamps, and more.

The Minecraft 1.21.5 update has also overhauled spawn egg designs, added ambient sounds to deserts and badlands, introduced several quality-of-life features, and implemented numerous bug fixes. Continue reading to check the patch notes for the Minecraft 1.21.5 update for Java Edition.

• The trades of the Cartographer and Wandering Trader have been updated
• Bundles can now be found in some of the Chests in Villages
