Release Notes - KatIPAuth v1.3.0

Major Improvements

• H2 Database Migration: Replaced JSON-based storage with an embedded H2 database for more reliable and persistent IP binding data. Existing data is automatically migrated from the legacy format on first load.
• Enhanced Login Pipeline: Overhauled pre-login checks for UUID and IP binding with improved subnet-aware logic and more precise kick messages that explain exactly why access was denied.
• Expanded Message Customization: Added new configurable messages for additional block scenarios (uuid-ip-mismatch, ip-uuid-mismatch, max-accounts) alongside the existing fallback message.

New Features & Tools

• Improved Discord Embeds: Webhook alerts now include richer detail and improved formatting for better log visibility at a glance.
• Config Auto-Update Improvements: Missing debug and security options (including verbose and max-accounts-per-ip) are now automatically added to your config.yml when upgrading.

Commands & Permissions

• /ipforce <player>: New admin command (ipauth.admin) that unbinds a player's UUID-IP pair without kicking them — their next join will register a fresh binding.

Security & Stability

• Safer URL Handling: Replaced the deprecated URL constructor with URI.create() to prevent malformed URL errors.
• Cleaner Reload Logic: Removed unused IPStorage dependency from IPReloadCommand and updated instantiation to match the refactored storage layer.
• Storage Initialization Refactor: Replaced storage.load() with storage.initialize() for a more predictable and reliable startup sequence.

Release Notes - KatIPAuth v1.2.0

Major Improvements
