            <li>Change the internal format of Hash database pages, storing items in
sorted order.  There are no externally visible changes, and hash
databases using historic on-page formats do not require an explicit
upgrade.  (However, upgrading existing databases can offer significant
performance improvements.) [#15017]</li>
            <li>Fix a bug preventing LSNs from being reset on hash databases when
the databases were configured with a non-standard hash function.
