Last week's Minecraft snapshot arrived a day late. However, this week Minecraft developers have released it according to their usual schedule. Minecraft 1.18 snapshot 21w39a is now out for Java Edition players.

Minecraft Caves and Cliffs Part 2 is Mojang's most ambitious update. This update would change the way Minecrafters remember caves and mountains. The last couple of snapshots were all about world generation features added in experimental snapshots.

The new snapshot 21w39a is "advanced" compared to the previous few snapshots. Players can now upgrade their older worlds to the latest 1.18 snapshot. However, this feature is still in development and has many issues. Players can download the new snapshot to report bugs and test the blending technology.

Last week's Bedrock beta replaced the bedrock layer with deepslate in old worlds. Developers are now working on bringing this feature to Java Edition. In snapshot 21w39a, players can play their old worlds, but the old chunks are not yet updated. Below the bedrock layer, players can only find empty air spaces.

Developers have also added four advancements for the Caves and Cliffs Part 2 update. Players can download Minecraft 1.18 snapshot 21w39a to test the transition of old worlds to new.

Unlike Bedrock Edtion, players do not need to sign up for testing snapshots. Anybody can download Java Edition snapshots using the Minecraft launcher.

With Minecraft 21w39a snapshot, players can now upgrade their old worlds. However, players are highly recommended to backup their worlds before moving them to the new snapshot as new chunks next to the old ones won't blend in future snapshots.

Players can create a new world in version 1.17 and move it to snapshot 21w39a to understand how blending works in the latest snapshot. This way, players won't have to worry about backing up their worlds.
