• Adds support for Minecraft 1.21.9 and 1.21.10

• #608 The RecipeArgument no longer throws any exceptions on Spigot
• #494, #503 Fixes the ConcurrentModificationException from happening when registering/unregistering commands at runtime

Module Changes

• #414, #517 Splits up the CommandAPI into modules specific for Paper and Spigot:
• Removes the commandapi-bukkit-shade module and the commandapi-bukkit-shade-mojang-mapped module
• Adds the commandapi-paper-core and the commandapi-paper-shade modules which are made to work on Paper
• Adds the commandapi-spigot-core and the commandapi-spigot-shade modules which are made to work on Spigot
• Adds the commandapi-paper-test-toolkit and the commandapi-spigot-test-toolkit which are replacing commandapi-bukkit-test-toolkit for Paper and Spigot respectively
• Moves and adds a few Kotlin DSL modules:
  • commandapi-core-kotlin -> commandapi-kotlin-core
  • commandapi-bukkit-kotlin -> commandapi-kotlin-bukkit
  • commandapi-velocity-kotlin -> commandapi-kotlin-velocity
  • Newly added: commandapi-kotlin-paper
  • Newly added: commandapi-kotlin-spigot

New features

• On Paper it is now possible to register commands at bootstrap

API Changes

• Changes the CommandAPIBukkitConfig class into an abstract one in favour of the newly added CommandAPIPaperConfig or CommandAPISpigotConfig classes, depending on the modules you use
• The FloatRangeArgument has been renamed to DoubleRangeArgument and now returns a DoubleRange
• The PlayerArgument and OfflinePlayerArgument have been replaced by the PlayerProfileArgument which returns a List<PlayerProfile>. The PlayerProfile class changes depending on if you are on Paper or on Spigot. Use the EntitySelectorArgument.OnePlayer if you want a Player object.
• The AsyncOfflinePlayerArgument has been replaced by the AsyncPlayerProfileArgument
• The ChatArgument, ChatComponentArgument and ChatColorArgument do no longer have any Adventure prefixes and return different types depending on the platform.
• The ChatArgument returns a SignedMessage object on Paper. Also resolves #381
• The BlockStateArgument now returns a BlockState object instead of a BlockData object

Config Changes

• Replaces the use-latest-nms-version and be-lenient-for-minor-versions config options with a fallback-to-latest-nms config option:
  • When loading the CommandAPI and this config option is set to true it will first check if the current version is supported and chooses that
  • In case the current version isn't a supported version, the CommandAPI will choose the latest nms version available which might or might not work correctly
  • This config option is set to true by default on Paper and false on Spigot
