 ### 🚀 Distribution Detection Enhancement Release
 
 #### Added
-- **Robust Distribution Detection System**
-  - 5-method fallback detection (/etc/os-release, /etc/redhat-release, /etc/debian_version, lsb_release, manual file checks)
-  - Container environment detection (Docker, Podman, LXC, WSL) with user warnings
-  - Advanced version normalization with regex parsing and bc calculator
-  - Comprehensive unit testing (66+ test cases, 98.5% success rate)
-  - Enterprise-grade error handling with detailed logging
+- **Webmin Integration**
+  - Web-based system administration interface
+  - Automatic firewall configuration for port 10000
+  - SSL configuration and session timeout optimization
+  - Multi-distribution support (Ubuntu/Debian, Fedora, openSUSE)
+
+- **Advanced Memory Optimization**
+  - vm.swappiness=10 for reduced aggressive swapping
+  - vm.vfs_cache_pressure=50 for better file cache retention
+  - Dedicated sysctl configuration file for NAS workloads
+  - Immediate application without reboot requirement
+
+- **Enhanced Docker Configuration**
+  - Optimized daemon.json with overlay2 storage driver
+  - Log rotation (10MB max size, 3 files)
+  - Performance tuning (live-restore, userland-proxy=false)
+  - Resource limits and metrics endpoint configuration
 
 - **Enhanced Security Documentation**
   - New SECURITY.md with comprehensive security policy
