## NEW FEATURES
### 1. Cross-Version Compatibility Layer
#### VersionCompat Class
// New in VersionCompat.java (~120 lines)
public static boolean isVersionGreaterOrEqual(int major, int minor, int patch)
public static boolean isModern() // 1.19+
public static boolean hasAdventureAPI() // 1.16.5+ with Paper
public static String getVersionString() // e.g., "1.20.4"
public static int getMajorVersion() // e.g., 20
**Impact:** Plugin now runs on ANY Minecraft version 1.16.5+ without modification
---
#### ChatCompat Class
// New in ChatCompat.java (~90 lines)
public static void sendMessage(Player p, String msg)
public static void sendActionBar(Player p, String msg) // Fallback to chat on 1.15
public static void sendTitle(Player p, String title, String subtitle)
public static String translateColorCodes(String msg) // &c → proper format
**Impact:** Server administrators no longer need separate plugins for different versions
---
#### EventCompat Class
// New in EventCompat.java (~80 lines)
public static String getPlayerName(Player p) // Never null
public static String getPlayerIP(Player p) // Never null, returns "0.0.0.0" if unavailable
public static boolean hasPermission(Player p, String perm) // Fallback to isOp()
public static void kickPlayer(Player p, String reason) // Safe kick with message
**Impact:** Eliminates version-specific crashes and compatibility issues
---
### 2. Advanced Cache Statistics & Monitoring
#### CacheStats Inner Class
// New in CacheManager.java
public class CacheStats {
private long hits;
private long misses;
public double getHitRatio() // (hits / (hits + misses))
public String toJson() // Serialize for logging
public void reset() // Clear metrics
public long getTotalRequests() // hits + misses
}
**Usage:**
```
/authAdmin cache
→ Cache Statistics:
• Hits: 1,245
• Misses: 155
• Hit Ratio: 88.9%
• Size: 287 / 10,000
```
**Impact:** Administrators can now monitor cache effectiveness and optimize settings
---
#### CacheEntry Wrapper Class
// New in CacheManager.java
private class CacheEntry {
private V value;
private long createdAt;
private long lastAccessed;
private int accessCount;
boolean isExpired(long ttlMillis) // Check if beyond TTL
void recordAccess() // Update on every hit
long getAgeMs() // Time since creation
}
**Impact:** Cache entries are automatically cleaned up, preventing memory leaks
---
### 3. LRU Cache Eviction Policy
#### evictLRU() Method
// New in CacheManager.java
public void evictLRU() {
// Sorts entries by lastAccessed timestamp
// Removes least-recently-used 10% of cache
// Example: 1000-entry cache removes 100 oldest entries
int entriesToRemove = (int) (cache.size() * 0.1);
cache.entrySet().stream()
.sorted((a, b) -> Long.compare(
a.getValue().lastAccessed,
b.getValue().lastAccessed
))
.limit(entriesToRemove)
.forEach(e -> cache.remove(e.getKey()));
}
**Benefits:**
- Memory automatically managed
- Old unused sessions cleared first
- Predictable cache behavior
**Impact:** Cache never grows unbounded; memory usage predictable and controllable
