1. Security Vulnerability Remediation
- Patched 6 CVEs related to IPsec VPN and SSL/TLS 1.3 decryption modules
- Enhanced SHA-3 certificate validation to prevent MITM attacks
- Extended FIPS 140-3 compliance for government deployments
2. Cluster Performance Optimization
- 25% faster HA synchronization in 16-node cluster configurations
- Reduced packet processing latency during DDoS mitigation scenarios
- Improved memory management for environments exceeding 1.5M concurrent sessions
3. Management Protocol Updates
- Expanded REST API support for bulk NAT policy deployment (JSON/YAML formats)
- Enhanced SNMP MIBs for real-time threat visibility
- Syslog correlation ID improvements for multi-device diagnostics
4. Platform Reliability
