Minecraft 1.21 Pre-release 1 patch notes: Leashable boats, portable ender pearls, and more

Minecraft 1.21 update is finally nearing its official release, as Mojang has revealed the first pre-release for the Tricky Trials update. Usually, pre-releases mainly offer bug fixes related to major features, but Mojang has brought several exciting changes and features with 1.21 Pre-release 1 this time.

With Minecraft 1.21 Pre-release 1, players can now use their leashes on boats and transfer ender pearls to other dimensions. Previously, both features didn't work as intended, but now they are finally fixed. Along with these two major fixes, Mojang also reverted a Fire Aspect enchantment parity that was going to be part of the Minecraft 1.21 update. However, developers have confirmed that it will return in a future release.

Additionally, the mace's attack speed has been changed. Let's go over all the changes and fixes in Minecraft 1.21 Pre-release 1.
