A lot has changed since the first 1.19.2 release! Changes include:
Swords can now block, although this is not visible to other players in multiplayer yet. Blocks have a time limit and cooldown similar to the 1.12 version of the mod.
Custom Shields are now present, although they do not serve any functional purpose yet.
A config file has been introduced; it is also currently not functional but should provide an example of what is yet to come!
