<para>The locking strategy for UNIX domain sockets has been
revised to improve concurrency; this change has yielded
substantial performance improvements on various SMP workloads
(in particular, MySQL on 8-way &arch.amd64; systems) with little
or no measured overhead on UP systems.</para>
<para>Several minor but widespread changes to the Newbus API have
been made In order to support some on-going work with interrupt
