New users getting started with 7.3.0 will be greeted by a completely redesigned onboarding wizard that gets your server configured and ready in about three minutes. It walks you through server name, time zone, language, SSH access, theme, boot method selection, and plugin installation in a clean step-by-step interface, with a summary screen to review everything before it's applied. The boot method choice (USB/Flash Drive or Internal Boot) is built directly into the flow, so new users encounter it from day one rather than discovering it later buried in settings. Existing users switching to Internal Boot can access the same wizard under Tools, Onboarding Wizard. This release includes several security fixes. Upgrade is recommended. The 7.3 kernel patches two local privilege escalation vulnerabilities: Copy Fail (CVE-2026-31431) and Dirty Frag (CVE-2025-43284), the latter previously addressed in 7.2.6. Users upgrading from 7.2.5 or earlier get both fixes in one update.
