PoSMP v1.3.5 Update

Released: October 5, 2025

What's New

Auction House Improvements

No more inconvenient purchases! Right-clicking an item now shows a confirmation screen before buying. You'll see exactly what you're purchasing, the price, and buttons to confirm or cancel. Much safer and clearer than the old double-click system.

TPA Request Fixes

Fixed the accept/decline buttons in TPA requests - they actually work now when you click them!

Bounty System Updates

• New command: Players can now cancel bounties with /bounty cancel <player> Be sure to give players the following permission: posmp.bounty.cancel.self
• Less spam: Bounty reminders now appear every 10 minutes instead of every 30 seconds
• Players who cancel bounties lose 50% of their fee and refunds the remainder to them (configurable for server owners) [bounty.yml]
• Fixed /Bounty map - typing player name - so you can bind map to the player you want to hunt! 

Why This Matters

• Safer item purchases with visual confirmation
• Working TPA buttons (no more frustration!)
• Quieter bounty notifications that don't spam chat

 Scoreboard.yml now allows you to switch server location (for ping). That's about it really!

PoSMP v1.3.4 - Patch Notes

Release Date: October 2, 2025

Overview

Version 1.3.4 brings critical bug fixes to the SellGUI system, comprehensive MySQL database support for 12+ features, and improved transaction history interface.

Database Support (MySQL + File Storage)

12 Features with MySQL Persistence

Full MySQL database support for data persistence across server restarts. All features support both MySQL and file-based storage (YAML/SQLite) with automatic fallback.

Features with Database Support: Home System, Team System, Stats System, Crystal Currency, AFK System, Settings System, Bounty System, Auction System, Build/Claims, Crates System, SellGUI System, Marriage System

Configuration Locations

Centralized Configuration (5 Features) File: plugins/PoSMP/config.yml

• Home, Team, Stats, Crystal, and AFK features use shared centralized storage in the player-data-storage section

Individual Feature Configurations (7 Features) Each feature has its own storage section in their respective config files:

• Settings: features/settings.yml
• Bounty: features/bounty.yml
• Auction: features/auction.yml
• Build: features/build.yml
• Crates: features/crates.yml
• SellGUI: features/sellgui.yml
• Marriage: features/marriage.yml

Example storage configuration:

storage:
  type: yaml 
 # Options: yaml, mysql

  mysql:
    host: 
localhost
    port: 
3306
    database: 
posmp
    username: 
root
    password:yourpassword

    table-prefix: posmp_

Database Features

• Automatic table creation
• Connection pooling with HikariCP
• Auto-reconnect and async operations
• Automatic fallback to file storage if MySQL unavailable
• Transaction support for data integrity

Critical Bug Fixes

SellGUI Payment System - CRITICAL FIX

Issue: Players were being paid 64x more than intended for all items sold.

• Example: 64 Birch Logs worth $128 total was paying $8,192

Fix: Removed duplicate multiplication in payment calculation methods.

Transaction History Values - CRITICAL FIX

Issue: Transaction history showed wildly incorrect values.

• Example: Sold 64 Carrots for $96, but history showed $6,758.40

Root Cause: When saving to database, history multiplied value by item amount again when value already included the full stack.

Fix: Removed duplicate multiplication when saving to history database. Note: Existing history entries will still show incorrect values - only new transactions after this update will be accurate.

Feature Improvements

Item Value Display - Permission Removal

Change: Removed permission requirement for viewing item values.

• All players can now see item values in tooltips and actionbar
• No posmp.itemvalue.actionbar permission required

Transaction History - Improved Clarity

Changes:

• Removed confusing "Avg/Item" from history displays
• Changed "Total Value" to "Total Payment" for clarity
• Individual items show "Worth: $X each" and "Sold for: $XXX"
• Fixed SQL query to properly sum all items in a transaction

Tax System - Disabled by Default

Tax rate set to 0.0 by default in configuration. Can be re-enabled by changing tax-rate in sellgui.yml.

Missing Message Configuration

Added missing tax-message configuration to messages section.

Technical Changes

• Fixed payment calculation.
• Fixed transaction history value storage
• Removed permission check from actionbar display for item values
• Updated transaction detail tooltip labels for clarity
• Added intelligent GUI item detection to prevent value tooltips on GUI buttons
• Added storage sections to all feature configs with MySQL examples
• Enhanced config.yml with centralized player-data-storage section

MySQL Migration (Optional)

1. Create MySQL database and user
2. Update configuration files (change type: yaml to type: mysql)
3. Restart server - tables will auto-create and data will migrate
4. Verify in console for successful initialization

Impact Summary

Known Issues

Hi all,

Two updates within a day? Yes, you got that right!

This update enhances on 1.2.0 update by allowing you to disable posmp feature commands to allow the use of other plugins. 

How it works:

• Lets say you would like to disable the built-in /sell command, to use another plugin like zSell. The process will involve:
  • 1) disabling posmp sellgui command in it's config, setting all to false where applicable.
  • Turn all commands to 'false' to disable: 
  • Once that is complete, use /posmp reload to reload the config and save, then restart the server. [osmp will then allow other plugins to have priority in registering their commands.

Feature Update:

- You can now disable individual features to use other plugins with PoSMP.

- If you have another plugin you want to use, for example /sell, instead of PoSMP conflicting with their /sell command, you can go to the config file of sellgui in PoSMP folder, set "enabled: false"

PoSMP 1.0.5 – Patch Notes

Features

PlaceholderAPI integration: Stabilized for TAB and scoreboards with working stats placeholders (kills, deaths, playtime) and crystals placeholder

New placeholders for use with PlaceholderAPI-enabled plugins like TAB:

• %posmp_stats_kills%
• %posmp_stats_deaths%
• %posmp_stats_playtime% (formatted)
• %posmp_stats_playtime_raw% (seconds)
• %posmp_crystal_amount%
• %posmp_team_name%

Placeholder optimization: Consolidated placeholder logic into single expansion (identifier "posmp"). Removed legacy duplicate team expansion to avoid collisions

Stats GUI improvements: Playtime now computed from tracked total + current session with no PAPI dependency

Crystals enhancements:

• Placeholder now reads CrystalFeature store by UUID and falls back to PlayerData to avoid showing 0
• Configuration improved: unlimited cap with 0 or -1 in features/crystal.yml
• settings.maximum-balance: 0 or -1 means unlimited (previously -1), default set to 0
• Message placeholders updated to %posmp_crystal_amount%

Bug Fixes

TAB values blank: Resolved by removing duplicate PlaceholderAPI expansion with same identifier and returning safe defaults when stats/crystal features are unavailable

Stats placeholders: Switched to direct method calls (no reflection) and ensured non-empty outputs

Playtime in GUI: Fixed to include current session and use internal tracking

Crystal placeholder stuck at 0: Now reads persisted store first with PlayerData fallback

Config Updates

features/crystal.yml now defaults to unlimited max balance using 0

Build/Packaging

Version bumped to 1.0.5

Commands to Reload

/papi reload /tab reload (or restart) /posmp reload (optional after deploying JAR)

• Configurable in features/team.yml with options for enabled, y-offset, instant tracking, update period, and format

Team Levels page: Team Info GUI Experience Bottle opens levels page showing current level, XP, next threshold, and benefits per level from config

Join request GUI: Clicking a team in Team List sends request and opens Accept/Deny GUI for owner. /team join <team> triggers same GUI flow

RTP multiverse support: features/rtp.yml multiverse section to pick overworld/nether/end/lobby world names. RTP respects configured world names instead of first world with matching environment

Team enhancements:

• Team list shows team level in item lore
• Team sidebar toggleable (default OFF) via gui.sidebar: false
• Team color selection GUI and back button fixed
• Kick GUI lists teammate heads reliably with UUID-based lookup

Chat improvements: Resolved raw %luckperms_prefix% by using PlaceholderAPI when present with fallback resolver for common placeholders when PlaceholderAPI is absent

Bug Fixes

AFK disable crash on shutdown: Avoid scheduling tasks while plugin disables

Duplicate messages eliminated:

• Team chat toggle now reports only once
• Kick duplicate notice removed (one source of truth from TeamFeature)

Display cleanup: Kick/leave immediately clears second-line nametag and below-name artifacts

Above-head display: Removed old label usage and replaced with armor-stand nametag for fully custom second line under player name

Config Updates

features/team.yml overhauled:

• New gui.nametag block for second line settings
• display.tab-format and display.chat-format simplified
• Benefits/levels retained with team list showing level in GUI lore
