This update should be compatible with worlds using version 1.7.2 as long as there is not a currently living Dragon, but as it is made for a new version of Minecraft, a backup is strongly recommended.

General:

• Updated Pack Format to 71 for Minecraft 1.21.5

Dragons:

• Adjusted the Frost Dragon's loot table. It now only drops one Goat Horn, which can be of a random instrument, along with an Enchanted Book with Frost Walker. Snow Blocks have also been added to this loot table.
