Ultimate Economy - 1.21.11 - 26.3

Backup your current Plugin folder before updating to 2.0-BETA Changed: * The plugin is now called UltimateEconomy and uses the folder plugins/UltimateEconomy/. DELETE THE OLD UltimateEconomyFree JAR when you add this one. Running both makes them fight over the economy and the commands. Newly added: + Player-to-player trading with a GUI (items and money), with staff spectate and trade history + /pay now asks you to confirm: /pay confirm or /pay cancel + PlaceholderAPI support (balance, baltop, currency, server totals) + Choose SQLite or YAML for balances (SQLite is the default and migrates from balances.yml automatically) + Choose SQLite or YAML for backup history + Optional balance cap + Batched saving with safe triggers (logout, trades, admin commands, big transactions) so the server does not write to disk on every payment + Bedrock (Floodgate) support, and NPC / fake accounts are no longer given balances + New admin commands: /eco setall, /eco purge, /eco repair, /eco convert, /eco storage + Works on Paper 1.21 up to 26.3, and on Folia (with VaultUnlocked) + AUTOMATIC IMPORT on the first start: if an old UltimateEconomyFree or UltimateEconomyPremium folder is found, your settings, balances, backup history (and trade logs) are copied into the new plugin. The old folder is only read, never changed. + A warning in the console, and to admins when they join, if an old UltimateEconomy plugin jar is still installed + New options added by future updates appear in your config.yml by themselves. Your values and your own comments are kept, and the old file is saved as config.yml.bak first + The /pay messages, the trade request / cooldown / distance / completed messages and the /eco import messages can be edited in config.yml Stability and performance improvements - All disk work runs on one background thread and is stopped in order on shutdown (trade system, commands, placeholders, storage, then I/O). - The update checker is asynchronous with a 5 s connect and a 10 s request timeout, and only runs one check at a time. - Folia: tasks use the Folia schedulers when running on Folia.
