+## v1.5.0
+
+- [New API] [commit](https://github.com/mdlayher/netlink/commit/53a1c10065e51077659ceedf921c8f0807abe8c0):
+  the `netlink.Config.PID` field can be used to specify an explicit port ID when

+- [Improvement]: more low-level functionality ported to
+  `github.com/mdlayher/socket`, reducing package complexity.
