What changed in the world
Minecraft's Trails & Tales update expanded the materials and activities available in a world. The Bedrock release notes list cherry groves and a cherry wood set, bamboo blocks and planks, and bamboo rafts. They also document camels and the archaeology features associated with suspicious blocks, brushes and pottery fragments.
These additions serve different purposes. A wood set expands construction choices; a biome changes what players can discover in newly generated terrain; archaeology gives players a different reason to inspect particular blocks. Calling all of them new blocks misses how exploration and building connect in the update.

Mojang publishes separate Java and Bedrock notes. The Java 1.20 record identifies the update as Trails & Tales and documents its changes and fixes. A tutorial should name the edition and version it uses, especially when commands, experimental settings or technical features are involved.
This explainer describes the 1.20 release rather than today's latest version. Before modifying a valued world, keep a backup and check the instructions for your edition. Do not assume that an early feature preview, an Education release and the original Java or Bedrock release share an identical schedule.
