4.2.0 - Player Guide, Mail Check, Economy-Aware GUIs & Safer Admin Tools

MailboxGUI 4.2.0 is a quality-of-life and polish update focused on better player onboarding, safer upgrades, cleaner economy handling, improved admin tools, and updated language support.

Highlights

• Added /mailbox guide and /mb guide to help players understand personal mailboxes, public Post Office boxes, Post Office NPCs, and how to get started.
• Added /mailbox check and /mb check to show new unchecked mail counts without opening the inbox.
• Improved Vault/economy detection so money and COD options are hidden from GUIs when unavailable.
• Added configurable money display formatting for money mail, admin money mail, COD prices, and COD return payments.
• Improved COD fail-safes so COD mail stays safely dormant if Vault/economy is unavailable and becomes usable again when support returns.
• Updated mailbox and Post Office sign wording for clearer personal mailbox and public access signs.
• Improved storage conversion commands with /mba convert current and simplified /mba convert <YAML|SQLITE|MYSQL>.
• Added /mailbox admin clean and /mba clean to safely clean MailboxGUI-generated backup files after confirming upgraded data is working.
• Improved backup organization under the plugin data folder.
• Improved Citizens Post Office NPC cleanup when NPCs are removed.
• Updated bundled language files and language upgrade handling for 4.2.0.

Economy & Storage Improvements

MailboxGUI now adapts better to servers with or without Vault economy support. Servers without economy can still use letters, packages, public Post Office boxes, Post Office NPCs, and physical mailbox gameplay, while economy-only features are hidden safely.

Storage conversion is also cleaner and safer, with current-storage detection, same-type conversion blocking, MySQL validation before switching, and clearer success/failure messages.

Upgrade Notes

Existing mail data should not require a wipe. Legacy YAML installs remain on YAML unless manually converted, and older mail/language data is upgraded safely where possible.
