Jan 1, 2026January 2026 monthly performance for juanfont/headscale focused on strengthening developer experience, reducing operational noise, and improving correctness in onboarding workflows. Delivered targeted documentation updates, clarified terminology (registration key vs machine key), and expanded coverage for Registration, Identity Model, and Tag Management, with cross-linking to headscale.net and ongoing site maintenance (copyright/version bumps). Implemented logging and messaging enhancements to reduce noise and improve troubleshooting for node key actions, including the removal of trace logs for pre-auth key creation and clearer messaging around converting a user-owned node to a tagged node. Resolved a critical bug in node expiration messaging to ensure success messages accurately indicate whether a node has expired or its expiration time was updated.
