+<h3>Title...</h3>
+
+<p>Description</p>
+
+-->
+
+<h3>Non-VME RTEMS targets now define pdevLibVME</h3>
+
+<p>Previously IOC executables that made calls to devLib routines would fail to
+link when built for some non-VME based RTEMS targets, which would have to be
+explicitly filtered out by sites that build Base for those targets.
+<a href="https://bugs.launchpad.net/epics-base/+bug/1841692">This fix</a> makes
+that no longer necessary, all RTEMS targets should now link although the IOC
+won't be able to be used with the VME I/O on those systems (that we don't have
+VMEbus I/O support for in libCom).</p>
+
+<h1 align="center">EPICS Release 7.0.3</h1>
+
+<h3>epicsTimeGetCurrent() optimization</h3>
+
+<p>Add a fast path to epicsTimeGetCurrent() and related calls
+in the common case where only the default OS current time provider is
+registered.  This path does not take the global mutex guarding
+the time providers list, potentially reducing lock contention.</p>
+
+<h3>dbEvent tweak Queue size</h3>
+
+<p>The size of the queue used by dbEvent to push monitor updates
+has been slightly increased based on DBR_TIME_DOUBLE to better fill
+an ethernet frame.  This may result in slightly fewer, but larger
+frames being sent.</p>
+
+<h3>mbbo/mbbiDirect number of bits as precision</h3>
+
+<p>Report NOBT as &quot;precision&quot; through the dbAccess API.
+This is not accessible through CA, but is planned to be used through
+QSRV.</p>
+
+<h1 align="center">EPICS Release 7.0.2.2</h1>
+
+<h3>Build System changes</h3>
+
+<ul>
+
+<li>The GNUmake build targets <tt>cvsclean</tt> and <tt>depclean</tt> are now
+available from any directory; previously they were only available from
+application top directories.</li>
+
+<li>The approach that EPICS Base uses for building submodules inside the parent
+module looks useful for support modules too. The rules for building submodules
+have been modified and extracted into a new <tt>RULES_MODULES</tt> file, so a
+support module will be able to use them too without having to copy them into its
+own <tt>modules/Makefile</tt>. There are some specific requirements that support
+modules and their submodules must follow, which are described as comments in the
+new <tt>base/configure/RULES_MODULES</tt> file itself.</li>
+
+</ul>
+
+<h3>EPICS_BASE_VERSION Update Policy change</h3>
+
+<p>In the past, a build of EPICS using sources checked out from the repository
+branch between official releases would have shown the version number of the
+previous release, followed by a <q>-DEV</q> suffix, for example
+<q>7.0.2.1-DEV</q>.</p>
+
+<p>The policy that controls when the number gets updated has been changed, and
+now immediately after a release has been tagged the version number will be
+updated to the next patch release version, plus the <q>-DEV</q> suffix as
+before. Thus following <q>7.0.2.2</q> the version number will show as
+<q>7.0.2.3-DEV</q>. This does not require the next official release to be
+numbered <q>7.0.2.3</q> though, it could become <q>7.0.3</q> or even
+<q>7.1.0</q> if the changes incorporated into it are more substantial than bug
+fixes.</p>
+
+<h3>Drop CLOCK_MONOTONIC_RAW from posix/osdMonotonic.c</h3>
+
+<p>Turns out this is ~10x slower to query than CLOCK_MONOTONIC.</p>

+<h3>Cleaning up with Multiple CA contexts in a Process</h3>
+
+<p>Bruno Martins reported a problem with the CA client library at shutdown in a
+process that uses multiple CA client contexts. The first context that triggers
+the CA client exit handler prevents any others from being able to clean up
+because it resets the ID of an internal epicsThreadPrivate variable which is
+shared by all clients. This action has been removed from the client library,
