ProVouchers

Added

• Localization: all plugin messages moved to lang/<code>.yml. Players see their client language when a matching file exists, otherwise locale.default. English fills in any missing keys.
• two-step-authentication: redeeming requires a second click within redeem.confirm-window-seconds. Prompt overridable per voucher.
• Reward preview: left-click a held voucher to see its loot and chances before redeeming. Controlled by redeem.left-click-preview.
• /voucher doctor: prints version, server, Java runtime, storage backend and pool state, content counts, detected integrations, locale, and metrics.
• /voucher reload <id>: reloads a single voucher or code file. A file that fails to parse keeps its loaded version.
• Vouchers can no longer be used as crafting ingredients or placed into anvils, grindstones, smithing tables, looms, cartography tables, stonecutters, or brewing stands.
• effects.sound: plays a sound on redeem, written as "key [volume] [pitch]". Silent during batch open.
• %random:min-max:name%: a named roll resolves once per redeem and repeats the same value wherever the name is reused, so a reward can give an amount and announce that same amount.
• %expiry%: renders the voucher's expiry in its name or lore as in 30d, on 2026-12-31, or never.
• expiry accepts plain dates (2026-12-31, valid through the end of that day in server time) and zone-less date-times, alongside durations and ISO-8601 instants.
• redeem.batch-open-quiet: batch open skips per-item messages, titles, and sounds.
• anti-dupe.notify.enabled: toggles staff duplicate alerts. The alert message supports {world}.

Changed

• Placeholders are now %player%, %arg%, and %random:min-max%. The curly forms still work but are deprecated; /voucher reload warns when a file uses them.
• Updated FastStats to 0.25.2.

Fixed

• Stackable vouchers from separate gives now stack with each other. The give time is stamped only when a relative expiry needs it.
