Hi!

The 2.4 update is mostly a QOL update with a couple bug fixes.

Shulker Box dyeing has been improved, the crafting inventory updates properly (the result item) and as such behaves a lot more like vanilla crafting.

If you are using the plugin as an API there is a new custom event fired: ShulkerBoxDyeEvent which is fired when clicking on the result dyed Shulker Box. This can be cancelled!
A custom event was used because CraftItemEvent is not meant to be manually called and would cause a recursive call to the event.

The /give <player> shulker_box & /give <player> shulker_shell command now has some messages similar to those of vanilla Minecraft.

Also, /give <player> shulker_shell now can include an amount. Such as /give stakdek12 shulker_shell 128.

Some items have been renamed when in the Shulker Box tool tip: "Lapis Lazuli Block" has been renamed to "Block of Lapis Lazuli", "Redstone" has been renamed to "Redstone Dust", and Anvil variants have been renamed from "Anvil" to "Anvil" (undamaged), "Slightly Damaged Anvil" and "Very Damaged Anvil" respectively.

And lastly, a bug which caused an extra folder to be created within the plugin folder has been fixed. This extra folder will not be created, and if you have it in the Shulkers plugin folder, you can safely delete it.
