## Changelog since v1.7.10

### Other notable changes

* Bugfix: master startup script on GCP no longer fails randomly due to concurrent iptables invocations. ([#55945](https://github.com/kubernetes/kubernetes/pull/55945), [@x13n](https://github.com/x13n))

- The deprecated feature gates GCERegionalPersistentDisk, EnableAggregatedDiscoveryTimeout and PersistentLocalVolumes are now unconditionally enabled and can no longer be specified in component invocations. ([#82472](https://github.com/kubernetes/kubernetes/pull/82472), [@draveness](https://github.com/draveness))

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>

Similarly, the expression
