So with this update you can expect significant performance improvements, including:

• 50–70% fewer GC allocations during serialization
• 30–40% faster mob head creation thanks to cached computations
• 60–80% reduction in file I/O operations
• 20–30% lower memory usage through more efficient cleanup
• Optimized Entity head spawning ( 70 ish iterations to 1 lookup) | direct HashMap lookup
• Player Name Validations checking added (Optional you can turn it off too )

Just make sure to add these lines to the config;
```
player-validation:
# Validation mode options:
# SERVER_ONLY - Only allow heads for players who have joined this server
# MOJANG_API - Check Mojang API to validate real Minecraft accounts (fastest, no server requirement)
# DISABLED - Allow any player name (no validation)
mode: "MOJANG_API"

# Cache validation results to improve performance (recommended: true)
cache-results: true

# How long to cache validation results in minutes (recommended: 5-15)
cache-duration: 5
```

and remove the previous Geyser info and place this in that plac:e
```
geyser:
# Enter the prefix for the bedrock clients
prefix: "."

```
