0.19 ➝ 0.20

Minecraft version

Updated to 1.21.6

ItemBehavior

• modifyClientSideStack now receives the server-side ItemStack instead of data: NamespacedCompound. The data can still be accessed by using the ItemStack.retrieveData extension functions on server: ItemStack.

commons-provider

Updated to 2.0.0-alpha.4, which contains the following breaking changes:

• Removed MutableProvider.defaultsTo, use orElse instead. (For CBF compounds, entry providers can now have a default value)
• Removed MutableProvider.orElse(Provider) with no replacement
• Removed MutableProvider.detached with no replacement
• Some extension functions, such as map and flatMap, are now member functions on Provider / MutableProvider, which means that you may need to remove some invalid imports.

Check out the updated commons-provider KDocs.

CBF

Updated to 1.0.0-alpha.2, which contains major changes to how custom serializers work.
Check out the updated CBF Docs and CBF KDocs.

InvUI

Updated to 2.0.0-alpha.14, which contains one breaking change:

• Removed Gui#remove(...) in favor of Gui#setSlotElement(..., null)
