For Developers
Future changes regarding API enumsEnums such as Biome implementing the Keyed interface will be converted to classes with public static final objects at some point. While some backwards compatibility will be provided, please try to avoid the use of switch statements, EnumMap and EnumSet on these, including the Material enum.
1.20 API changes
With 1.20, there is of course new API for the new features. Some notable breaks are:
SmithingRecipe
has been replaced withSmithingTrimRecipe
andSmithingTransformRecipe
InventoryType.SMITHING
now uses 1.20's new smithing table interfaceSign#isEditable()
has been deprecated in favor of a new method calledisWaxed
, same for its setter
API scheduled for removal
A bunch of old API has been scheduled for removal in 1.21, so please make sure you remove usages of these in your plugins:
- AsyncChatDecorateEvent#isPreview()
- PlayerLocaleChangeEvent
- PlayerInitialSpawnEvent
- WorldBorder#isInBounds(Location)
- EntityTransformedEvent
- ItemStackRecipeChoice
- HeightmapType
- All associated methods in Location and World
- All deprecated or removed GoalKeys in VanillaGoal
- StructureLocateEvent (not the new StructuresLocateEvent)
- Duplicate Effects
- World API
Hangar
As per the last big announcement, we now have our own website for you to upload your Paper, Bungee, and Velocity plugins to. There have been little updates in the past few weeks due to us being busy with other projects, including Paper, but rest assured we'll keep working on it! https://hangar.papermc.io/Experimental channel for builds
Our downloads API has different channels to distinguish builds - right now betweenexperimental
and default
. For future updates, we will no longer provide any early experimental builds on Discord, instead using the experimental
channel in our downloads API. This means that you will need to distinguish between channels in your scripts to avoid getting highly experimental and potentially breaking versions. Please adjust your download scripts accordingly. Experimental builds marked as such will be available to download on our homepage as well.
