 # Changelog
 
+## 2026-03-30 - 11.16.0 - feat(vpn)
+add destination-based VPN routing policy and standardize socket proxy forwarding
+
+- replace configurable VPN forwarding mode with socket-based forwarding and always enable proxy protocol support to SmartProxy from localhost
+- add destinationPolicy configuration for controlling default VPN traffic handling, including forceTarget, allow, and block rules
+- remove forwarding mode reporting from VPN status APIs, logs, and ops UI to reflect the simplified VPN runtime model
+- update @push.rocks/smartvpn to 1.14.0 to support the new VPN routing behavior
+
 ## 2026-03-30 - 11.15.0 - feat(vpn)
 add tag-based VPN route access control and support configured initial VPN clients
