kMoney 1.6.0

kMoney 1.6.0 introduces a complete inventory GUI for the economy system, expands Paper compatibility, and includes all performance and bug fixes released in 1.5.1.

Highlights

• Added a complete inventory-based interface for /money.
• Added GUI flows for payments, withdrawals, the balance leaderboard, and administration.
• Expanded support to 14 Paper releases, from Minecraft 1.21 through 26.2.
• Reduced the minimum runtime requirement to Java 21.
• Centralized economy operations so commands and menus use the same validation, messages, sounds, and balance logic.

New inventory GUI

• Running /money now opens a main menu showing the player's balance and available actions.
• Added dedicated menus for:
  • Paying another player.
  • Withdrawing money into checks.
  • Viewing the richest players.
  • Adding, removing, or setting player balances.
  • Reloading the plugin and toggling the admin join message.
• Added an online-player picker for payment and administration actions.
• Added chat-based amount input with support for cancel.
• Added permission-aware buttons so players only see actions they can use.
• Added configurable and translatable GUI titles, item names, lore, prompts, and navigation labels in messages.yml.
• Added gui.top.enabled to config.yml. Disable it to retain the classic chat output for /money top; console usage always uses chat output.

Economy and command improvements

• Added a shared EconomyActions service for payments, balance administration, and check withdrawals.
• Kept the existing command arguments available for direct command and console usage.
• Corrected command suggestions so all is only suggested where it is supported.
• Prevented integer overflow when requesting extremely high /money top pages.
• Expanded amount parsing and formatting with suffixes through TVG (1e72).

Performance and reliability

• Improved leaderboard cache access and concurrency behavior.
• Fixed zero-balance checks for values such as 0.0 by using scale-independent BigDecimal comparison.
• Fixed the displayed player name when attempting to remove money from an empty account.
• Improved MiniMessage parsing for tags containing quoted > characters and malformed multiline tags.
• Moved the update checker into the correct manager package.
• Reduced duplicated command logic through the economy-action refactor.

Compatibility

• Paper is the supported server platform.
• Supported Minecraft versions:
  • 1.21
  • 1.21.1 through 1.21.11
  • 26.1.1
  • 26.1.2
  • 26.2
• The plugin now emits Java 21-compatible bytecode while retaining Java 25 as its build toolchain.
• The project now compiles against the Paper 1.21 API to enforce the oldest supported API boundary.
• The development server version can be selected with -PminecraftVersion=<version> for compatibility testing.

Paper does not provide concrete server releases for Minecraft 1.21.2 or 26.1, so those versions are intentionally not listed.

Behavior changes

• /money opens the main GUI for players instead of printing the balance directly. Console senders continue to receive command-compatible output where applicable.
• /money admin opens the administration GUI when run by a player.
• /money top opens the leaderboard GUI by default. Set gui.top.enabled: false for the previous chat-based leaderboard.

Configuration notes

• Review the new gui section in config.yml.
• Add the new gui message section from messages.yml when maintaining customized configuration files.
• PlaceholderAPI, Vault, and VaultUnlocked remain optional integrations.
