 # Changelog
 
+## 2026-04-08 - 13.3.0 - feat(web-ui)
+reorganize network and security views into tabbed subviews with route-aware navigation
+
+- add URL-based subview support in app state and router for network and security sections
+- group routes, source profiles, network targets, and target profiles under the network view with tab navigation
+- split security into dedicated overview, blocked IPs, authentication, and email security subviews
+- update configuration navigation to deep-link directly to the network routes subview
+
 ## 2026-04-08 - 13.2.2 - fix(project)
