An End update from the future: Crystal Groves and Void Marshes, chorus trees, void crystals, the End Anchor and the Void Eye, shardlings and void rays you can fly on, and a crystal that cleanses sculk.
All your chests work as one inventory: the recipe book counts what's inside them and takes the items for you, the Items screen shows everything at once, and you can name a chest and follow a navigator to it.
Blueprints for builders: step inside a blueprint and build on your own private plot, then place the build as a hologram in the world and see exactly which blocks you still need to finish it.
Get used to what hurts you! Each of 16 damage types hurts 25% less per level, up to full immunity. Eat chorus fruit to learn to teleport (10) and dodge hits like an enderman (20). Dying forgets everything. Fabric, Minecraft 26.3.
