Large inline-signing changes should be less disruptive.
Signature generation is now done incrementally; the number
of signatures to be generated in each quantum is controlled
by "sig-signing-signatures <replaceable>number</replaceable>;".

Asynchronous zone loads were not handled correctly when the
zone load was already in progress; this could trigger a crash
in zt.c. [RT #37573]

Several bugs have been fixed in the RPZ implementation:
</para>
<itemizedlist>
<para>
Policy zones that did not specifically require recursion
could be treated as if they did; consequently, setting
<command>qname-wait-recurse no;</command> was
sometimes ineffective. This has been corrected.
In most configurations, behavioral changes due to this
fix will not be noticeable. [RT #39229]
</para>
</listitem>
<listitem>
<para>
The server could crash if policy zones were updated (e.g.
via <command>rndc reload</command> or an incoming zone
transfer) while RPZ processing was still ongoing for an
active query. [RT #39415]
</para>
</listitem>
<listitem>
<para>
On servers with one or more policy zones configured as
slaves, if a policy zone updated during regular operation
(rather than at startup) using a full zone reload, such as
via AXFR, a bug could allow the RPZ summary data to fall out
of sync, potentially leading to an assertion failure in
rpz.c when further incremental updates were made to the
zone, such as via IXFR. [RT #39567]
</para>
</listitem>
<listitem>
<para>
The server could match a shorter prefix than what was
available in CLIENT-IP policy triggers, and so, an
unexpected action could be taken. This has been
corrected. [RT #39481]
