Claimo

New:

• Item vouchers: an optional item section turns a code into a physical item (custom name, lore, custom model data, item_model on 1.21.2+, or a Nexo / ItemsAdder / CraftEngine item) redeemed by right-click; hand it out with /code give <players> <voucher> [amount] (selectors like @a supported), outdated items refresh themselves automatically
• /code giveoffline <player> <voucher> [amount] queues voucher items for offline players and delivers them on their next join (multiple queued wins stack)
• Per-player cooldown (e.g. a daily code) and starts activation windows; inactive codes are hidden from the GUI and tab-completion
• price: charge players through Vault when they redeem a code, with a confirmation step first (a dialog on 1.21.7+, redeem-again-within-10s on older servers)
• effects: celebrate a redeem with fireworks and particle shapes (burst, circle, sphere, helix)
• random: run one random command from cmd instead of all of them, with optional chance weights
• Requirement groups any / all / not with free nesting, e.g. (VIP or Premium) and 2h playtime
• /code generate <voucher> <amount> clones a code into hidden one-time copies and exports them to a text file
• Campaigns: generated codes belong to a campaign you can inspect (/code campaign info), void (disable), export or delete in one command
• Redeem history stored in the database: /code history <code|player> and /code stats <code> (uses, unique players, revenue, last redeem)
• /code info <voucher> prints a code's full configuration and its use count
• Update checker: Claimo periodically checks GitHub for new releases and notifies the console and admins with the claimo.update permission on join
• Admin action log (logs/admin.log): give, generate, purge, campaign and creator actions; the redeem log now includes the price paid
• The in-game creator gained price, item and effects pages, and editing no longer drops hand-written keys like cooldown or starts
• Expanded addon API: redeemWithResult with a RedeemResult outcome, usage/cooldown readers, voucher item helpers, programmatic voucher create/delete/generate, custom reward actions (action:<name> cmd lines) and Voucher.flattenedRequirements()

Fix:

• Uses are now reserved atomically in the storage backend, so two servers sharing a database can no longer double-redeem the last use of a global pool
• Admin-only subcommands no longer appear in tab-completion for players without claimo.admin
• /code purge also clears the deleted codes' cooldowns for online players
• The custom requirement no longer errors without PlaceholderAPI, and both placeholder and value resolve placeholders (plus a new <value_parsed> message placeholder)
