+<h3>Routine <tt>epicsTempName()</tt> removed from libCom</h3>
 
-<!-- Insert inherited items immediately below here ... -->
+<p>This routine was a simple wrapper around the C89 function <tt>tmpnam()</tt>
+which is now seen as unsafe and causes warning messages to be generated by
+most modern compilers. The two internal uses of this function have been
+modified to call <tt>epicsTempFile()</tt> instead. We were unable to find any
+published code that used this function, so it was removed immediately instead
+of being deprecated.</p>
 
+<h3>DBD Parsing of Record Types</h3>
+
+<p>The Perl DBD file parser has been made slightly more liberal; the order in
+which DBD files must be parsed is now more flexible, so that a record type
+definition can now be parsed after a device support that referred to that
+record type. A warning message will be displayed when the device support is
+seen, but the subsequent loading of the record type will be accepted without
+triggering an error. See
+<a href="https://bugs.launchpad.net/epics-base/+bug/1801145">Launchpad bug
+#1801145</a>.</p>
+
+<h3>menuScan and several record types documented with POD</h3>
+
+<p>The EPICS Wiki pages describing a number of standard record types has been
+converted into the Perl POD documentation format and added to the DBD files,
+so at build-time an HTML version of these documents is generated and installed
+into the htmls directory. Thanks to Tony Pietryla.</p>
+
+<h3>CA client tools learned <tt>-V</tt> option</h3>
+
+<p>This displays the version numbers of EPICS Base and the CA protocol.</p>
