Minecraft Bedrock Epochs Timeline

Explore the timeline of world-generation epochs in Minecraft Bedrock. Each epoch spans a range of Bedrock versions where seed outcomes and terrain generation remain broadly consistent. Major updates to terrain, biomes, structures, and world height mark the beginning of new epochs. This community-sourced classification helps players identify which seeds remain compatible between versions.

An epoch is a period of time where Minecraft’s world-generation algorithm stays stable.

Whenever Mojang makes a significant change to terrain noise, biome distribution, or structure placement, a new epoch begins. Seeds created within the same epoch will always generate identical worlds, while seeds between epochs will produce entirely new landscapes—even if the seed number is the same.

Each epoch entry below explains what changed and links directly to the game versions it covers. This helps players understand which seeds remain compatible and how world-generation evolved across updates.

Epoch

Tricky Trials

Adds underground Trial Chambers and related content — new structure placement influences seeds.

Epoch

Trails & Tales

Archaeology and trail ruins; Cherry Grove — localized seed effects.

Epoch

The Wild Update

Deep Dark & Mangrove Swamp; Ancient Cities — biome/structure placements shift.

Epoch

Caves & Cliffs

Height range expanded (-64..320), new noise, huge caves and lofty mountains — major seed reset.

Epoch

Pre-1.18 Transition

Part 1 content lands without terrain rewrite — seeds largely stable ahead of 1.18.

Epoch

Nether Update

Nether biomes/structures overhaul; overworld terrain unchanged, nether seed experience changes significantly.

Epoch

Post-Village (Buzzy Bees)

Bees and honey; minor world-gen impact — overworld seeds broadly stable vs Village & Pillage.

Epoch

Village & Pillage

Villages regenerate with biome-specific layouts; pillager outposts added — structure placement differs across seeds.

Epoch

Post-Aquatic / Pre-Village

Feature parity & systems updates without terrain/biome overhauls — seeds broadly stable vs Aquatic.
