Major update 1.10 is already here! Update tag: "The Silent Kid Update" Changelog:
Improved the German translation (thanks @mfnalex!)
Stopped you from being able to enchant already enchanted items - use anvils, duh
Removed all the traces of trident enchantments existence: a newcomer won't even know they existed!
Switched to Java 16 completely, now you have to use Java 16 or higher
Moved all commands into subcommands of /underscoreenchants (/ue)
This update is the last one this month, and possibly January won't have any updates as well. However, the 2.0 update will bring so much new stuff that UnderscoreEnchants will finally become a competitor to the paid ones.
