with an explicit receiver as its first argument; it has signature
</p>

<pre>
func(tv T, a int) int
</pre>

<p>
That function may be called normally with an explicit receiver, so
these five invocations are equivalent:
</p>

<pre>
t.Mv(7)
T.Mv(t, 7)
(T).Mv(t, 7)
f1 := T.Mv; f1(t, 7)
f2 := (T).Mv; f2(t, 7)
</pre>

<p>
Similarly, the expression

* Fix bug where master startup script on GCP failed randomly due to concurrent iptables invocations. ([#55945](https://github.com/kubernetes/kubernetes/pull/55945), [@x13n](https://github.com/x13n))



# v1.8.4

[Documentation](https://docs.k8s.io) & [Examples](https://releases.k8s.io/release-1.8/examples)

*   Masquerading rules are now added by default to GCE/GKE ([#55178](https://github.com/kubernetes/kubernetes/pull/55178),[ @dnardo](https://github.com/dnardo))
*   Fixed master startup issues with concurrent iptables invocations. ([#55945](https://github.com/kubernetes/kubernetes/pull/55945),[ @x13n](https://github.com/x13n))
