+	    <p>When multiplying a number by itself, a word beyond the
+	    number on the heap could be read (and ignored). This bug
+	    was extremely unlikely to actually cause a real
+	    problem.</p>

+          <p>
+	    Fix bug where doing <c>seq_trace:reset_trace()</c> while
+	    another process was doing a garbage collection could
+	    cause the run-time system to segfault.</p>

+        </item>
+        <item>
+          <p>
+	    Fix reading of ancillary data from packet oriented
+	    sockets on old Linux kernel versions. Without this fix,
+	    getting the data would cause the port to enter an
+	    infinite loop.</p>
+          <p>
+	    Own Id: OTP-15494</p>
+        </item>
+        <item>
+          <p>
+	    Fix bug where crash dumping or doing
+	    <c>erlang:system_info(procs)</c> while another process
+	    was doing a garbage collection could cause the run-time
+	    system to segfault.</p>
+          <p>
+	    Own Id: OTP-15527</p>
+        </item>
+        <item>
+          <p>
+	    Fix <c>erlang:system_info(kernel_poll)</c> to return
+	    correct value. Before this fix, the call always returned
+	    <c>false</c>.</p>
+          <p>
+	    Own Id: OTP-15556</p>
+        </item>
+        <item>
+          <p>
+	    Fix bug in <c>enif_make_map_from_arrays</c> that would
+	    produce broken maps when number of keys were 32. Bug
+	    exists since OTP 21.0.</p>
+          <p>
+	    Own Id: OTP-15567</p>
+        </item>
+        <item>
+          <p>
+	    Fix a bug in <c>binary:encode_unsigned</c> that may cause
+	    a read of uninitialized memory.</p>
+          <p>
+	    The bug existed since the function was added (OTP
+	    R16B02).</p>
+          <p>
+	    Own Id: OTP-15583 Aux Id: PR-2118 </p>
+        </item>
+        <item>
+          <p>
+	    Fixed a bug that could cause <c>heart</c> to kill an
+	    exiting node before it had time to flush all buffered
+	    writes. If environment variable
+	    <c>HEART_KILL_SIGNAL=SIGABRT</c> was set a superfluous
+	    core dump could also be generated.</p>
+          <p>
+	    Own Id: OTP-15599 Aux Id: ERIERL-298 </p>
+        </item>
+        <item>
+          <p>
+	    Fix <c>enif_consume_timeslice</c> to be a no-op on dirty
+	    scheduler and not crash debug compiled emulator.</p>
+          <p>
+	    Own Id: OTP-15604</p>
+        </item>
+        <item>
+          <p>
+	    Fixed macro redefinition warnings.</p>

+        </item>
+        <item>
+          <p>
+	    <c>to_erl</c> fixed to not garble terminal input beyond
+	    7-bit ASCII.</p>

+        </item>
+        <item>
+          <p>
+	    Fixed a bug in all <c>ets:select*</c> and
+	    <c>ets:match*</c> functions that could in some rare cases
+	    lead to very poor performance.</p>

+    <section><title>Improvements and New Features</title>
+      <list>
+        <item>
+          <p>
+	    Add <c>erlang:system_flag(system_logger, Pid)</c> and
+	    <c>erlang:system_info(system_logger)</c>. This
+	    system_flag can be used to set the process that will
+	    receive the logging messages generated by ERTS.</p>

+        <item>
+	    <p><c>integer_to_list/2</c> and
+	    <c>integer_to_binary/2</c> are now implemented in C,
+	    improving their performance.</p>
+          <p>
+	    Own Id: OTP-15503 Aux Id: PR-2052 </p>
+        </item>
+        <item>
+          <p>
+	    Improved <c>term_to_binary</c> to do more fair reduction
+	    count and yielding when encoding large byte lists
+	    (strings).</p>
+          <p>
+	    Own Id: OTP-15514 Aux Id: ERL-774 </p>
+        </item>
+        <item>
+          <p>
+	    Made internal port drivers more robust against
+	    <c>erlang:port_control</c> with invalid arguments and
+	    added documentation warnings about such abuse.</p>
+          <p>
+	    Own Id: OTP-15555 Aux Id: ERIERL-231 </p>
+        </item>
+        <item>
+          <p>
+	    Fix bug on NetBSD where the <c>exit_status</c> from a
+	    port program would never be sent.</p>
+          <p>
+	    Own Id: OTP-15558 Aux Id: ERL-725 </p>
+        </item>
+        <item>
+	    <p>There is a new function <c>persistent:term(Key,
+	    Default)</c> to allow specifying a default when looking
+	    up a persistent term.</p>
+          <p>
+	    Own Id: OTP-15576 Aux Id: ERL-843 </p>
+        </item>
+        <item>
+	    <p>A transitory emulator option '<c>+ztma true</c>' has
+	    been added to allow running existing BEAM code that
+	    relies on "tuple calls" (dispatch on parameterized
+	    modules) which has been compiled under OTP 20 or earlier.
+	    This option will be removed in OTP 22, so such modules
+	    should eventually be recompiled with the
+	    <c>+tuple_calls</c> option.</p>
