Minecraft: Bedrock Edition Beta 1.18.0.20 is the first proper release for 'Caves and Cliffs Update' Part Two

What you need to know

• Mojang Studios has been quietly testing features from 1.18 'Caves and Cliffs Update' Part Two in Minecraft betas and snapshots.
• With the latest Minecraft: Bedrock Edition snapshot, Mojang Studios is finally moving those experimental changes into the spotlight.
• Minecraft: Bedrock Edition Beta 1.18.0.20 is the first build to sit under the 1.18 version umbrella, and is now available to testers.
• There are tons of features, changes, and fixes for players to test in this beta, most of which are being brought out from the "Experimental Features" toggle.

The journey for Minecraft to reach the second half of the Caves and Cliffs Update has been a long and winding one, but Mojang Studios has tirelessly continued their work. Today, a huge milestone is being reached in the development phase, as Minecraft: Bedrock Edition 1.18.0.20 officially breaks cover and becomes available to Minecraft testers on Xbox, Windows, and Android devices.

The latest Minecraft beta is the first build to move under the 1.18 version umbrella that will contain Part Two of the Caves and Cliffs Update. While a version number is ultimately arbitrary and doesn't affect much, what does matter is that all of the features and changes that were previously being hidden under the "Experimental Features" toggle are now out in the open and affect nearly all worlds in this beta. This means 1.18 Caves and Cliffs Update Part Two features are now enabled by default, and will inevitably be tested by considerably more players in the beta program.

We may hear more about the 1.18 Caves and Cliffs Update Part Two (and when it might release) during Minecraft Live 2021 later this year, and even what other games Mojang might be working on. Until then, though, Minecraft continues to be one of the best Xbox games around, with this constant influx of testable features confirming the notion.

In case you missed it, Minecraft's Steve and Alex are becoming amiibo figures for the Switch. These figures aren't coming until sometime in 2022, but will almost certainly be considered some of the best Minecraft toys and gifts when they do.
