Overview
Premium features historically covered advanced routing, TUN behavior, rule providers, script rules and diagnostics. Support depends on the core and client you use.
Compatibility
Do not assume every GUI client supports every Premium-era feature. Mihomo-based clients may support similar features with different names or syntax.
Safe usage
Enable advanced features only after basic proxying works. Keep separate profiles for experiments and daily use.
