 # Changelog
 
+## 2026-03-31 - 11.21.5 - fix(routing)
+apply VPN route allowlists dynamically after VPN clients load
+
+- Moves VPN security injection for hardcoded and programmatic routes into RouteConfigManager.applyRoutes() so allowlists are generated from current VPN client state.
+- Re-applies routes after starting the VPN manager to ensure tag-based ipAllowLists are available once VPN clients are loaded.
+- Avoids caching constructor routes with stale VPN security baked in while preserving HTTP/3 route augmentation.
+
 ## 2026-03-31 - 11.21.4 - fix(deps)
 bump @push.rocks/smartvpn to 1.16.4
