🌟 xLogin v1.0.8-Pre — Universal Authentication System

A powerful, all-in-one authentication solution designed for high-performance networks and standalone servers. This update brings full cross-platform compatibility, database-free proxy setups, and critical security fixes.

---

✨ Main Features

• Universal Compatibility: A single .jar file works simultaneously across Paper/Spigot, Velocity, BungeeCord, and Waterfall.
• Database-Free Proxy Mode: The proxy module (Velocity/Bungee) can now operate completely without a MySQL database. If no database is configured, it automatically falls back to the official Mojang API to detect premium accounts.
• Session Caching: Players switching between backend servers within the same network won't need to re-authenticate during the configured session lifetime.
• Strict Pre-Auth Restrictions: Unauthenticated players are completely restricted from moving, moving their camera, chatting, opening inventories, or executing unauthorized commands.
• Login Timeout: Automatically kicks players who fail to log in within a customizable time limit.
• Message Anti-Spam: Configurable intervals for login/register reminder messages to keep the player chat clean.
• Dynamic Command Hiding: Safely hides /login, /register, and /captcha from the tab-complete suggestions immediately after a player authenticates (can be toggled on/off).

🔧 Security & Fixes

• Premium Registration Fix: Solved issues regarding auto-premium-registration. When disabled, premium players without an existing account must register manually as intended.
• Automatic Message Fallback: Older .yml configuration files will no longer trigger Missing: translation strings. The plugin now automatically reads missing keys from the default language files inside the .jar.
• Smarter Proxy Communication: When running in proxy mode, backend Paper servers will no longer query the Mojang API, optimizing performance by trusting the Proxy's UUID generation ($v4$ for premium, $v3$ for offline accounts).
