Leon van Kammen developed a security isolation feature for the Copyparty repository, focusing on hardening the application using bubblewrap sandboxing. He implemented a shell script that launches Copyparty in a separate, isolated environment, reducing the attack surface and supporting secure deployment practices. Alongside the technical solution, Leon produced comprehensive documentation to guide users through the sandboxing process. His work emphasized Linux security best practices and shell scripting, enabling easier testing in isolated contexts and improving compliance readiness. Over the course of the month, Leon concentrated on engineering depth and clarity, delivering a focused security enhancement without addressing bug fixes.
January 2026 highlights: Delivered XRSH App Configuration Entry in YunoHost/apps, expanding the apps catalog to include XR and 3D apps. This feature enhances onboarding and deployment of XR solutions by ensuring proper categorization and status in the apps configuration, and by aligning associated assets. Auxiliary maintenance included updating apps.toml and the logos directory to reflect the new entry, improving catalog consistency and branding across the repository. No critical bugs reported this month; focus remained on feature completeness, maintainability, and cross-team collaboration.
