Minecraft 1.21 Servers

What 1.21 added, and why it took servers a while to move

Tricky Trials landed in June 2024, and its centrepiece is the trial chamber: a generated copper-and-tuff dungeon full of trial spawners that stop producing once you clear them. Run one with an ominous bottle active and the vaults pay out better. It also brought the Breeze, the Bogged and the mace, which hits harder the further you fall onto something.

For a server, the crafter mattered more than any of that. Automated crafting had been a modded feature for a decade, and having it in the base game changes what a redstone farm can do without a single plugin. Copper bulbs and the full tuff block set filled out building palettes at the same time.

The 1.21 line kept moving after release — the pale garden and the creaking arrived in 1.21.4, and later point releases added more again. That is worth remembering when you read a listing, because 1.21 can mean anything from 1.21.1 to the newest patch. Most servers run Paper behind ViaVersion and accept a range of clients, so connecting is usually the fastest way to find out.
