 <!-- Insert new items immediately below here ... -->
 
+<h3>Warning indicators in msi (and macLib) output</h3>
+
+<p>The libCom macro expansion library has been modified so that when the
+SUPPRESS_WARNINGS flag is set it will no longer include any <tt>,undefined</tt>
+or <tt>,recursive</tt> indicators in its output when undefined or recursive
+macros are encountered. These indicators were harmless when the output was fed
+into an IOC along with a definition for the macro, but when the <tt>msi</tt>
+tool was used to generate other kinds of files they caused problems. If the
+<tt>msi -V</tt> flag is used the markers will still be present in the output
+whenever the appropriate condition is seen.</p>
+
+<h3>Improvements to msi</h3>
+
+<p>In addition to fixing its response to discovering parsing errors in its
+substitution input file (reported as Launchpad
+<a href="https://bugs.launchpad.net/epics-base/+bug/1503661">bug #1503661</a>)
+so it now deletes the incomplete output file, the msi program has been cleaned
+up a little bit internally.</p>
+
+<h3>All array records now post monitors on their array-length fields</h3>
+
+<p>The waveform record has been posting monitors on its NORD field since Base
+3.15.0.1; we finally got around to doing the equivalent in all the other
+built-in record types, which even required modifying device support in some
+cases. This fixes <a href="https://bugs.launchpad.net/epics-base/+bug/1730727">
+Launchpad bug #1730727</a>.</p>
+
+<h3>HOWTO: Converting Wiki Record Reference to POD</h3>
+
+<p>Some documentation has been added to the <tt>dbdToHtml.pl</tt> script
+explaining how Perl POD (Plain Old Documentation) markup can be added to
+<tt>.dbd</tt> files to generate HTML documentation for the record types. To see
+these instructions, run <tt>perl&nbsp;bin/&lt;host&gt;/dbdToHtml.pl&nbsp;-H</tt>
+or <tt>perldoc&nbsp;bin/&lt;host&gt;/dbdToHtml.pl</tt>.</p>
+
+<h3>Fix problem with numeric soft events</h3>
+
+<p>Changing from numeric to named soft events introduced an incompatibility
+when a numeric event 1-255 is converted from a DOUBLE, e.g. from a calc record.
+The <tt>post_event()</tt> API is not marked deprecated any more.
+
+<p>Also <code>scanpel</code> has been modified to accept a glob pattern for
+event name filtering and to show events with no connected records as well.</p>
+
+<h3>Add osiSockOptMcastLoop_t and osiSockTest</h3>
+
+<p>Added a new OS-independent typedef for multicast socket options, and a test
+file to check their correct operation.<p>
+
+<h3>Support for CONFIG_SITE.local in Base</h3>
+
+<p>This feature is mostly meant for use by developers; configuration
+settings that would normally appear in Base/configure/CONFIG_SITE can now
+be put in a locally created base/configure/CONFIG_SITE.local file instead
+of having go modify or replace the original. A new .gitignore pattern
+tells git to ignore all configure/*.local files.</p>
+
+
+<h2 align="center">Changes from the 3.14 branch since 3.15.5</h2>
+
+<!-- Insert inherited items immediately below here ... -->
+
+<h3>Fix broken <tt>EPICS_IOC_LOG_FILE_LIMIT=0</tt> setting</h3>
+
+<p>The Application Developers' Guide says this is allowed and disables the
+limit on the log-file, but it hasn't actually worked for some time (if ever).
+Note that the iocLogServer will be removed from newer Base release sometime
+soon as its functionality can be implemented by other dedicated log servers
+such as logstash or syslog-ng.</p>
+
+<p>Fixes <a href="https://bugs.launchpad.net/bugs/1786858">lp:1786858</a>
+and part of <a href="https://bugs.launchpad.net/bugs/1786966">lp:1786966</a>.
+</p>
+
+<h3>Cleanup of startup directory</h3>
+
+<p>The files in the startup directory have not been maintained in recent years
+and have grown crufty (technical term). This release includes the following
+updates to these files:</p>
+
+<ul>
+
+<li>The Perl <tt>EpicsHostArch.pl</tt> script has been rewritten, and support
+for a few previously missing host architectures has been added to it.</li>
+
+<li>The <tt>EpicsHostArch.pl</tt> script has also been moved into the standard
+<tt>src/tools</tt> directory, from where it will be installed into
+<tt>lib/perl</tt>. In this new location it is no longer executable, so it must
+be run by the <tt>perl</tt> executable.</li>
+
+<li>The build system has been adjusted to look for <tt>EpicsHostArch.pl</tt> in
+both places if the <tt>EPICS_HOST_ARCH</tt> environment variable has not been
+set at build-time.</li>
+
+<li>Sites that used the original Perl script to set <tt>EPICS_HOST_ARCH</tt> as
+part of their standard environment will need to adjust their scripts when they
+upgrade to this release.</li>
+
+<li>The <tt>EpicsHostArch</tt> shell script has been replaced with a wrapper
+routine that calls the Perl <tt>EpicsHostArch.pl</tt> script. Sites that rely on
+this script to set <tt>EPICS_HOST_ARCH</tt> should consider switching to the
+Perl script instead.</li>
+
+<li>The <tt>Site.cshrc</tt> and <tt>Site.profile</tt> files have been renamed to
+<tt>unix.csh</tt> and <tt>unix.sh</tt>, respectively.</li>

+<h3>Recent Apple XCode Build Issues</h3>
+
+<p>The latest version of XCode will not compile calls to <tt>system()</tt> or
+<tt>clock_settime()</tt> for iOS targets. There were several places in Base
+where these were being compiled, although there were probably never called. The
+code has now been modified to permit iOS builds to complete again.</p>
+
+<h3>Prevent illegal alarm severities</h3>
+
+<p>A check has been added to <tt>recGblResetAlarms()</tt> that prevents records
+from getting an alarm severity higher than INVALID_ALARM. It is still possible
+for a field like HSV to get set to a value that is not a legal alarm severity,
+but the core IOC code should never copy such a value into a record's SEVR or
+ACKS fields. With this fix the record's alarm severity will be limited to
+INVALID_ALARM.</p>
+
+<h3>Fixes for Launchpad bugs</h3>
+
+<p>The following launchpad bugs have fixes included:</p>
+
+<ul>
+<li><a href="https://bugs.launchpad.net/epics-base/+bug/1786320">
+    lp: #1786320</a>, dbCa subscribes twice to ENUM</li>

+</ul>
+
+<h3>Updated VxWorks Timezone settings</h3>
+
+<p>Removed the settings for 2017; fixed the hour of the change for MET.</p>
+
+<h3>Fixed camonitor server side relative timestamps bug</h3>
+
+<p>Initialize the first time-stamp from the first monitor, not the client-side
+current time in this configuration.</p>
+
+<h3>Build changes for MSVC</h3>
+
+<p>Windows builds using Visual Studio 2015 and later now use the <tt>-FS</tt>
+compiler option to allow parallel builds to work properly.</p>
+
+<p>We now give the <tt>-FC</tt> option to tell the compiler to print absolute
+paths for source files in diagnostic messages.</p>
+
+<h3>Extend maximum Posix epicsEventWaitWithTimeout() delay</h3>
+
+<p>The Posix implementation of epicsEventWaitWithTimeout() was limiting the
+timeout delay to at most 60 minutes (3600.0 seconds). This has been changed to
+10 years; significantly longer maximum delays cause problems on systems where
+<tt>time_t</tt> is still a signed 32-bit integer so cannot represent absolute
+time-stamps after 2038-01-19. Our assumption is that such 32-bit systems will
+have been retired before the year 2028, but some additional tests have been
+added to the epicsTimeTest program to detect and fail if this assumption is
+violated.</p>
+
+<h3>New test-related make targets</h3>
+
+<p>This release adds several new make targets intended for use by developers
+and Continuous Integration systems which simplify the task of running the
+built-in self-test programs and viewing the results. Since these targets are
+intended for limited use they can have requirements for the build host which
+go beyond the standard minimum set needed to build and run Base.</p>
+
+<blockquote>
+
+<h4><tt>test-results</tt> &mdash; Summarize test results</h4>
+
+<p>The new make target <tt>test-results</tt> will run the self-tests if
+necessary to generate a TAP file for each test, then summarizes the TAP output
+files in each test directory in turn, displaying the details of any failures.
+This step uses the program <q>prove</q> which comes with Perl, but also needs
+<q>cat</q> to be provided in the default search path so will not work on most
+Windows systems.</p>
+
+<h4><tt>junitfiles</tt> &mdash; Convert test results to JUnit XML Format</h4>
+
+<p>The new make target <tt>junitfiles</tt> will run the self-tests if necessary
+and then convert the TAP output files into the more commonly-supported JUnit
+XML format. The program that performs this conversion needs the Perl module
+<q><tt>XML::Generator</tt></q> to have been installed.</p>
+
+<h4><tt>clean-tests</tt> &mdash; Delete test result files</h4>
+
+<p>The new make target <tt>clean-tests</tt> removes any test result files from
+previous test runs. It cleans both TAP and JUnit XML files.</p>
+
+</blockquote>
+
+<h3>Fix DNS related crash on exit</h3>
+
+<p>The attempt to fix DNS related delays for short lived CLI programs (eg. caget)
+in lp:1527636 introduced a bug which cased these short lived clients to crash on exit.
+This bug should now be fixed.</p>
+
+<h3>Server bind issue on Windows</h3>
+
+<p>When a National Instruments network variables CA server is already running on
+a Windows system and an IOC or PCAS server is started, the IOC's attempt to
+bind a TCP socket to the CA server port number fails, but Windows returns a
+different error status value than the IOC is expecting in that circumstance
+(because the National Instruments code requests exclusive use of that port,
+unlike the EPICS code) so the IOC fails to start properly. The relevent EPICS
+bind() checks have now been updated so the IOC will request that a dynamic port
+number be allocated for this TCP socket instead when this happens.</p>
+
+<h3>Checking Periodic Scan Rates</h3>
+
+<p>Code has been added to the IOC startup to better protect it against bad
+periodic scan rates, including against locales where <q><tt>.</tt></q> is not
+accepted as a decimal separator character. If the scan period in a menuScan
+choice string cannot be parsed, the associated periodic scan thread will no
+longer be started by the IOC and a warning message will be displayed at iocInit
+time. The <tt>scanppl</tt> command will also flag the faulty menuScan value.</p>
