+**This is the last release of package netlink that supports Go 1.11.**

+- [Improvement] [#165](https://github.com/mdlayher/netlink/pull/165):
+  `netlink.Conn` `SetReadBuffer` and `SetWriteBuffer` methods now attempt the
+  `SO_*BUFFORCE` socket options to possibly ignore system limits given elevated
+  caller permissions. Thanks @MarkusBauer.
+- [Note]
+  [commit](https://github.com/mdlayher/netlink/commit/c5f8ab79aa345dcfcf7f14d746659ca1b80a0ecc):
+  `netlink.Conn.Close` has had a long-standing bug
+  [#162](https://github.com/mdlayher/netlink/pull/162) related to internal
+  concurrency handling where a call to `Close` is not sufficient to unblock
+  pending reads. To effectively fix this issue, it is necessary to drop support
+  for Go 1.11 and below. This will be fixed in a future release, but a
+  workaround is noted in the method documentation as of now.
