Prefix v2.0.0 | MODERN FOUNDATION
The biggest update in Prefix history. Completely modernized architecture, all critical bugs fixed, SOLID principles applied throughout.

PLATFORM UPGRADE:

• Java 17 — modern language features, pattern matching, records
• Spigot/Paper 1.20+ — compiled against the latest stable API
• Gradle build modernization — toolchain, UTF-8 encoding, release targeting
• Removed legacy BungeeCord chat JAR (now Maven dependency)
• Removed legacy 15-character limits on prefixes and team names
• Fixed deprecated HoverEvent constructor — uses modern Content-based API
  • ⚡ Impact: Future-proof foundation that will support Minecraft updates for years

CRITICAL FIXES (5):

• Fixed: Chat no longer crashes when a player mentions another player's name
  • ⚡ Impact: Eliminates server-wide ConcurrentModificationException crashes
• Fixed: /prefix chat and /prefix tab commands now correctly include the last word of the prefix
  • ⚡ Impact: "/prefix chat admin &4[Admin]" now works as expected — no more empty prefixes
• Fixed: Players can no longer crash the server by typing %s or %d in chat
  • ⚡ Impact: Closes a critical exploit that could be used to crash any server running Prefix
• Fixed: Tablist no longer throws NullPointerException during class loading
  • ⚡ Impact: Reliable tablist display from the moment the plugin loads
• Fixed: Module initialization no longer enters an inconsistent state on failure
  • ⚡ Impact: Clean error handling during plugin startup

BUG FIXES (14):

• Fixed: Group creation no longer has contradictory success/failure logic
• Fixed: Configuration reload no longer loads the file twice
• Fixed: Command handler is now thread-safe for concurrent players
• Fixed: Permission strings standardized across plugin.yml, code, and help messages
• Fixed: All exceptions now log full stack traces for easier debugging
• Fixed: Logger now shows [Prefix] tag in console output
• Fixed: Group null-check now correctly uses Result pattern
• Fixed: Group assignment validates group exists before saving
• Fixed: Color code commands no longer crash on single-character input
• Fixed: Group name field is now immutable — prevents silent config desync
• Fixed: Tablist character limits updated from legacy 15 to modern 64+ characters
• Fixed: Tab weight system now supports any integer, not just 0-9
• Fixed: Resource leak in configuration reload closed
• Fixed: Tablist getGroup() double call eliminated

SOLID ARCHITECTURE REFACTORING:

• SubCommand interface — all 10 subcommands now implement execute() pattern
  • → Cleaner than constructor-based execution, testable, extensible
• PGroup factory methods — loadOrCreate() and create() replace I/O-heavy constructors
  • → Constructor is now side-effect-free (no file reads/writes)
• Dependency Injection — Data passed via constructors throughout the codebase
  • → No more static PrefixModule.getData() calls in model/event classes
• HelpMessage data-driven — 128 lines of duplicated code → 40 lines with HelpEntry record
• Chat event handler split into buildFormat() + handleMentions() (SRP)
  • ⚡ Impact: Clean, maintainable, testable codebase ready for rapid feature development

CLEAN CONSOLE LOGGING:

• Logger.sendMessage() — players get colored messages, console gets clean [INFO] logs
• Logger.sendWarning() — config issues logged at [WARNING] level
• Logger.sendError() — real errors logged at [SEVERE] level
• All color codes automatically stripped from console output
  • ⚡ Impact: Professional, readable server logs without formatting artifacts

CODE QUALITY:

• Result.java methods renamed to Java camelCase conventions
• Language.getLanguage() is now static — cleaner API
• Removed unnecessary type casts in configuration access
• Removed unused HTTP-style status enum values
• Removed unused MinecraftVersion utility class (dead code)
• Removed unused Data.plugin reference
• Arrays.copyOfRange replaces manual System.arraycopy
• isEmpty() replaces equals("") throughout codebase
• ITask Javadoc corrected (ticks, not milliseconds)
• Module.java CommandMap reflection with proper exception handling
• /prefix info now shows version, build number, and clickable website link
• build.gradle modernized — removed unnecessary manifest block, added UTF-8 encoding

⚠️ BREAKING CHANGES:

• Requires Java 17 or higher (was Java 8)
• Requires Minecraft 1.20 or higher (was 1.13)
• Looking for older versions? Use Prefix v1.3.1 for pre-1.20 support

Config: Existing config files are fully compatible — no changes needed

Compatibility: Spigot/Paper 1.20+ | Java 17
