+-----------------------
+
+### Changes
+- Allow installing routes with no outbound interfaces
+- Reinitialize VIFs on reload in case of new interfaces
+- Handle cases when interfaces change ifindex, i.e. they've first been
+  removed and then re-added with the same name
+
+### Fixes
+- Fix VIF leak when deleting interfaces with MRDISC enabled
+- Fix handling when an (S,G) moves to another IIF.  This fixes issues
+  where the SMCRoute kernel cache was out of sync with the kernel MFC
+- Fix handling of lost/disabled interfaces at reload.  This fixes a
+  couple of issues where routes were not updated properly at runtime
+- Update interface flags on reload, this fixes issues when SMCRoute
+  failed to detect interfaces that had their MULTICAST flag set or
+  cleared at runtime
+. Skip `setsockopt()` for IPC sockets.  This fixes warnings in syslog
+  about failing to disable `MULTICAST_LOOP` and `MULTICAST_ALL`
