+	    Fix performance bug in pre-allocators that could cause
+	    them to permanently fall back on normal more expensive
+	    memory allocation. Pre-allocators are used for quick
+	    allocation of short lived meta data used by messages and
+	    other scheduled tasks. Bug exists since OTP_R15B02.</p>

+	    Fixed bug in operator <c>bxor</c> causing erroneuos
+	    result when one operand is a big <em>negative</em>
+	    integer with the lowest <c>N*W</c> bits as zero and the
+	    other operand not larger than <c>N*W</c> bits. <c>N</c>
+	    is an integer of 1 or larger and <c>W</c> is 32 or 64
+	    depending on word size.</p>

+	    A timer internal bit-field used for storing scheduler id
+	    was too small. As a result, VM internal timer data
+	    structures could become inconsistent when using 1024
+	    schedulers on the system. Note that systems with less
+	    than 1024 schedulers are not effected by this bug.</p>
+          <p>
+	    This bug was introduced in ERTS version 7.0 (OTP 18.0).</p>

+	    Fixed bug in <c>binary_to_term</c> and
+	    <c>binary_to_atom</c> that could cause VM crash.
+	    Typically happens when the last character of an UTF8
+	    string is in the range 128 to 255, but truncated to only
+	    one byte. Bug exists in <c>binary_to_term</c> since ERTS
+	    version 5.10.2 (OTP_R16B01) and <c>binary_to_atom</c>
+	    since ERTS version 9.0 (OTP-20.0).</p>

+	    Calls to <c>erl_drv_send_term()</c> or

+	    initial attack, which may require thousands of server
+	    requests, during the handshake phase of the targeted
+	    session within the window of the configured handshake
+	    timeout. This attack may be conducted against any TLS
+	    session using RSA signatures, but only if cipher suites
+	    using RSA key exchange are also enabled on the server.
+	    The limited window of opportunity, limitations in
+	    bandwidth, and latency make this attack significantly
+	    more difficult to execute. </p> <p> RSA key exchange is
+	    enabled by default although least prioritized if server
+	    order is honored. For such a cipher suite to be chosen it
+	    must also be supported by the client and probably the

-    <title>Operator "--"</title>
-     <p>The "<c>--</c>" operator has a complexity
-     proportional to the product of the length of its operands.
-     This means that the operator is very slow if both of its operands
-     are long lists:</p>
-
-        <p><em>DO NOT</em></p>
-        <code type="none"><!CDATA
-        HugeList1 -- HugeList2></code>
-
-     <p>Instead use the <seealso marker="stdlib:ordsets">ordsets</seealso>
-     module in STDLIB:</p>
-
-        <p><em>DO</em></p>
-        <code type="none">
-        HugeSet1 = ordsets:from_list(HugeList1),
-        HugeSet2 = ordsets:from_list(HugeList2),
-        ordsets:subtract(HugeSet1, HugeSet2)</code>
-
-     <p>Obviously, that code does not work if the original order
-     of the list is important. If the order of the list must be
-     preserved, do as follows:</p>
-
-        <p><em>DO</em></p>
-        <code type="none"><!CDATA
-        Set = gb_sets:from_list(HugeList2),
-        E || E <- HugeList1, not gb_sets:is_element(E, Set)></code>
-
-     <note><p>This code behaves differently from "<c>--</c>"
-     if the lists contain duplicate elements (one occurrence
-     of an element in HugeList2 removes <em>all</em>
-     occurrences in HugeList1.)</p>
-     <p>Also, this code compares lists elements using the
-     "<c>==</c>" operator, while "<c>--</c>" uses the "<c>=:=</c>" operator.
-     If that difference is important, <c>sets</c> can be used instead of
-     <c>gb_sets</c>, but <c>sets:from_list/1</c> is much
-     slower than <c>gb_sets:from_list/1</c> for long lists.</p></note>
-
-     <p>Using the "<c>--</c>" operator to delete an element
-     from a list is not a performance problem:</p>
-
-        <p><em>OK</em></p>
-        <code type="none">
-        HugeList1 -- Element</code>
