November 2025 focused on strengthening reliability, security, and developer experience across the Agama suite and its documentation. Key operational improvements include robust HTTP proxy support for the self-update workflow with user-configurable proxy settings via boot parameters or interactive prompts, environment-based proxy handling to avoid logging sensitive URLs, and improved logging to reduce exposure of sensitive data. Fixed fallback handling for the registration server and ensured consistent systemd status reporting in both initramfs and root image, enhancing update reliability in edge cases. Retained AMD GPU firmware during installation to ensure hardware compatibility, and reset the libzypp resolvables before new selections to prevent interference during package resolution. Reduced build surface by dropping 32-bit and PPC64-BE builds for Agama to improve stability and CI efficiency. Documentation and tooling saw significant progress: self-update documentation and autoinstall profile editing guides, plus a major upgrade of the documentation site tooling (Docusaurus 3.9.2, Node.js 22) to improve performance and maintainability. Translations merged from SLE-16 to address internationalization gaps. Overall, these changes improve deployment reliability, security, developer productivity, and user guidance.
