    Important: After installing this firmware, we strongly recommend performing a factory-default reset to activate every new security adjustment.

    Security Enhancements:
    – Password Policy Upgrade – Minimum of 10 characters, including at least one letter, one digit, and one special character; disallows consecutive identical characters; hardens defense against brute-force attacks.
    – HTTPS on 8443 – Management interface now served over TLS by default.
    – UPnP Disabled – Universal Plug and Play starts in the off state for reduced surface exposure.
    – AiCloud Authentication Hardening (CWE-287) – Added layered verification.
    – Authentication Logic Refactor – Removed redundant code paths for a lean sign-in flow.
    – Memory Safety Guard (CWE-476) – Introduced null-reference protections across critical services.
    – Enhanced IPsec Parameter Validation – The existing input checks have been hardened.
    – Data Exposure Mitigation (CWE-200) – Reinforced controls on sensitive pathways.
    – Detailed Audit Trails – Expanded logging within the authentication module.

    System Improvements:
    – Connection Stability – Core algorithms refined for steadier links.
    – Scheduling Accuracy – Timed tasks execute reliably under PPPoE, PPTP and L2TP WAN modes.
    – Client List Maintenance – Resolved an issue that prevented offline devices from being removed from the client list.
