According to the search results, the next major Minecraft update is version 1.21. The update is expected to be released in June 2024. The update will feature new challenges for combat-loving players in the form of a new structure called Trial Chambers, which will have different rooms full of challenges and deadly mobs, but also supply chests. Each chamber will be procedurally generated, so players will have a new environment to explore each time they find one. The update is also expected to expand forests and archaeology, with new mobs such as the Grizzly Bear and new features like digging up shards of clay to turn them into pottery. The update will also introduce new blocks, including copper and tuff blocks.
