     * Behavior change:
        * DaemonSet pods will be created on nodes with .spec.unschedulable=true and will
not be evicted from nodes whose Ready condition is false.
        * Updates to the pod template are now permitted. To perform a rolling update of a
DaemonSet, update the pod template and then delete its pods one by one; they
will be replaced using the updated template.
     * Spec change:

    //  * URI is much more strict than HttpUrl or URL on what's accepted.
    //
    // HttpUrl is quite lenient with what characters it accepts. In particular, characters like '{'
    // and '"' are permitted but unlikely to occur in real-world URLs. Unfortunately we can't just
    // lock it down due to URL templating: "http://{env}.{dc}.example.com".

jumps to labels:
</p>

<pre>
label:
	MOVW $0, R1
	JMP label
</pre>

<p>
Each label is visible only within the function in which it is defined.
It is therefore permitted for multiple functions in a file to define
and use the same label names.
Direct jumps and call instructions can target text symbols,
such as <code>name(SB)</code>, but not offsets from symbols,

but are otherwise ignored.
