September 2025 (Normation/rudder) delivered security-hardening, reliability, and platform-expansion wins. Key TLS/SSL hardening and Apache TLS template improvements established configurable peer authentication, certificate pinning/validation with custom CAs, flexible server certificate usage, and SSL settings with default Debian config generation. Resolved a Debian 12 install issue by ensuring the policy-server UUID retrieval works and added installation of TLS-related Apache templates. Implemented robust security patches for tracing vulnerabilities and an XSS vulnerability in ammonia, along with dependency updates to strengthen the security posture. Hardened optional-field handling by allowing empty/whitespace strings and added tests to ensure correctness. Enhanced CI/build tooling to support ARM64/armhf Debian environments and added licensing checks via latest cargo-deny. Improved documentation on detection of reboot and service restart across Zypper, APT, and Yum, and fixed logging to ensure proper info-level messages. Also improved secure shared folder file downloads using the enhanced HTTPS transfer script. These changes deliver stronger security, broader platform support, better observability, and measurable business value.
