Minecraft 1.21 Pre-Release 1

We're bringing you the first Pre-Release of 1.21 with leashable boats, portal-able Ender Pearls and bug fixes!

With this snapshot, we are temporarily removing the functionality of lighting blocks on fire using the Fire Aspect enchantment, as we want to refine it further. This functionality will be reintroduced in a later release.

Happy portaling! ;)
