Changes

MailboxGUI 6.1.0

Messages And Packages

  • Added optional messages to packages, COD packages, and money mail through composition, supported commands, scheduled mail, and the API.
  • Messages remain attached to accepted and returned COD packages.
  • Expanded packages to 28 content slots and removed the obsolete configurable package-size setting.
  • Improved preservation of custom item metadata in packages and item templates.

Formatting And Letters

  • Added compact HEX colors and visual MiniMessage support, including gradients, while retaining legacy & formatting.
  • Added /n line breaks for paper letters and package/money messages, with a maximum of 17 rendered body lines.
  • Added independent paper/book letter sending settings and a customizable, localized book information page.
  • Improved physical mailbox closing behavior when reading book letters.

GUI Customization

  • Added optional gui.yml customization with shared navigation controls, recipient icons, mail variants, and floating new-mail item appearances.
  • Added CustomModelData, supported modern item-model fields, and optional ItemsAdder item support.
  • Added /mb settings resourcepack on|off|auto, automatic pack-status fallback, and a resource-pack integration API.
  • gui.yml generates only when customization is enabled and reloads through /mba reload.

Languages And Commands

  • Added Brazilian Portuguese, bringing support to 16 languages.
  • Expanded translations and country-aware date/time formatting.
  • Added localized command aliases, help, and tab completion while retaining English commands.
  • Consolidated player sending under /mb send <letter|package|money>.
  • Reorganized settings help and added /mb settings notification status.
  • Integrated optional DiscBridge controls under /mb settings discord and /mba discord.

Public Access And Reliability

  • Renamed Post Office terminology to Public Access Mailboxes/NPCs, including configuration and Dynmap integration.
  • Public mailbox unregistering now uses Shift-Right-Click.
  • Added administrator package deletion in player inbox management.
  • Improved inbox refreshes, package claims, item-template loading, and older-server mail recognition.
  • Delayed mail now uses absolute delivery deadlines; existing queued delivery times are preserved.
  • Fixed reloads overwriting configuration edits and improved storage conversion and upgrade safeguards.
  • Added data-version-7 migration and expanded /mba clean backup coverage.
  • Improved Citizens NPC import protection.

API And Compatibility

  • Expanded APIs for mail queries, mutations, events, scheduling, custom items, and notification integrations.
  • Added PlaceholderAPI values for mail counts, capacity, delivery, expiration, kits, and preferences.
  • Updated compatibility handling for Spigot, Paper, and Purpur 1.18.2–1.21.11 and 26.1–26.3.
  • /mba updatecheck can report newer release, beta, and alpha builds; installation still follows the configured release channel.

Before Updating

Back up the plugin folder and database. Keep existing configuration, language files, and data so the upgrader can preserve customizations.
