-      <list>
-        <item>
-	    <p>Changed the default behaviour of <c>.erlang</c>
-	    loading: <c>.erlang</c> is no longer loaded from the
-	    current directory. <c>c:erlangrc(PathList)</c> can be
-	    used to search and load an <c>.erlang</c> file from user
-	    specified directories.</p> <p><c>escript</c>,
-	    <c>erlc</c>, <c>dialyzer</c> and <c>typer</c> no longer
-	    load an <c>.erlang</c> at all.</p>
-          <p>
-	    *** POTENTIAL INCOMPATIBILITY ***</p>
-          <p>
-	    Own Id: OTP-14439</p>
-        </item>
-        <item>
-	    <p>Support for "tuple calls" have been removed from the
-	    run-time system. Tuple calls was an undocumented and
-	    unsupported feature which allowed the module argument for
-	    an apply operation to be a tuple: <c>Var = dict:new(),
-	    Var:size()</c>. This "feature" frequently caused
-	    confusion, especially when such call failed. The
-	    stacktrace would point out functions that don't exist in
-	    the source code.</p>
-	    <p>For legacy code that need to use parameterized modules
-	    or tuple calls for some other reason, there is a new
-	    compiler option called <c>tuple_calls</c>. When this
-	    option is given, the compiler will generate extra code
-	    that emulates the old behavior for calls where the module
-	    is a variable.</p>

-	    *** POTENTIAL INCOMPATIBILITY ***</p>

-	    Own Id: OTP-14497</p>

-        <item>
-	    <p>In code such as <c>example({ok, Val}) -&gt; {ok,
-	    Val}.</c> a tuple would be built. The compiler will now
-	    automatically rewrite the code to
-	    <c>example({ok,Val}=Tuple) -&gt; Tuple.</c> which will
-	    reduce code size, execution time, and remove GC
-	    pressure.</p>

-        <item>
-	    <p>The optimization of <c>case</c> expression where only
-	    one of the case arms can execute successfully has been
-	    improved.</p>
-          <p>
-	    Own Id: OTP-14525</p>
-        </item>
-        <item>
-	    <p>Some uses of binary matching has been slightly
-	    improved, eliminating unnecessary register shuffling.</p>
-          <p>
-	    Own Id: OTP-14594 Aux Id: ERL-444 </p>
-        </item>
-        <item>
-	    <p>There is a new <c>{compile_info,Info}</c> option for
-	    the compiler that allows BEAM-based languages such as
-	    Elixir and LFE to add their own compiler versions.</p>
-          <p>
-	    Own Id: OTP-14615 Aux Id: PR-1558 </p>
-        </item>
-        <item>
-	    <p>Loaded BEAM code in a 64-bit system requires less
-	    memory because of better packing of operands for
-	    instructions.</p>
-	    <p>These memory savings were achieved by major
-	    improvements to the <c>beam_makeops</c> scripts used when
-	    building the run time system and BEAM compiler. There is
-	    also new for documentation for <c>beam_makeops</c> that
-	    describes how new BEAM instructions and loader
-	    transformations can be implemented. The documentation is
-	    found in here in a source directory or git repository:
-	    erts/emulator/internal_doc/beam_makeops.md. An online
-	    version can be found here:
-	    https://github.com/erlang/otp/blob/master/erts/emulator/internal_doc/beam_makeops.md</p>

-        <item>
-	    <p>Size calculations for binary constructions has been
-	    somewhat optimized, producing smaller code.</p>
-          <p>
-	    Own Id: OTP-14654</p>
-        </item>
-        <item>
-	    <p>When the value returned from a '<c>catch</c>'
-	    expression is ignored, no stacktrace will be built if an
-	    exception is caught. That will save time and produce less
-	    garbage. There are also some minor optimizations of
-	    '<c>try</c>/<c>catch</c>' both in the compiler and
-	    run-time system.</p>
-          <p>
-	    Own Id: OTP-14683</p>
-        </item>
-        <item>
-	    <p>There is a new syntax in '<c>try/catch</c>' for
-	    retrieving the stacktrace without calling
-	    '<c>erlang:get_stacktrace/0</c>'. See the reference
-	    manual for a description of the new syntax. The
-	    '<c>erlang:get_stacktrace/0</c>' BIF is now
-	    deprecated.</p>

-        <item>
-	    <p>The following is an internal change in the compiler,
-	    that is not noticeable for normal use of the compiler:
-	    The module <c>v3_life</c> has been removed. Its
-	    functionality has been simplified and integrated into
-	    <c>v3_codegen</c>.</p>
-          <p>
-	    Own Id: OTP-14712</p>
-        </item>
-        <item>
-	    <p>The optimization of binary matching that delays
-	    creation of sub binaries (see the Efficiency Guide) could
-	    be thwarted by the argument order and could be necessary
-	    to change the argument order. The compiler has now become
-	    smarter and can handle any argument order.</p>
-          <p>
-	    Own Id: OTP-14774</p>
-        </item>
-        <item>
-	    <p>When the compiler was faced with complex case
-	    expressions it would unnecessarily allocate stack
-	    elements and shuffle data between x and y registers.
-	    Improved code generation to only allocate a stack frame
-	    when strictly necessary.</p>
-          <p>
-	    Own Id: OTP-14808 Aux Id: ERL-514 </p>
-        </item>
-        <item>
-	    <p>There is a new option '<c>makedep_side_effect</c>' for
-	    the compiler and <c>-MMD</c> for '<c>erlc</c>' that
-	    generates dependencies and continues to compile as
-	    normal.</p>
-          <p>
-	    Own Id: OTP-14830</p>
-        </item>
-        <item>
-	    <p>When compiling modules with huge functions, the
-	    compiler would generate a lot of atoms for its internal,
-	    sometimes so many that the atom table would overflow. The
-	    compiler has been rewritten to generate far less internal
-	    atoms to avoid filling the atom table.</p>
-          <p>
-	    Own Id: OTP-14968 Aux Id: ERL-563 </p>
-        </item>
-        <item>
-	    <p>External funs with literal values for module, name,
-	    and arity (e.g. <c>erlang:abs/1</c>) are now treated as
-	    literals. That means more efficient code that produces
-	    less garbage on the heap.</p>
-          <p>
-	    Own Id: OTP-15003</p>
-        </item>
-        <item>
-	    <p>Two new guards BIFs operating on maps have been added:
-	    <c>map_get/2</c> and <c>is_map_key/2</c>. They do the
-	    same as <c>maps:get/2</c> and <c>maps:is_key/2</c>,
-	    respectively, except that they are allowed to be used in
-	    guards.</p>
-          <p>
-	    Own Id: OTP-15037 Aux Id: PR-1784, PR-1802 </p>
-        </item>
-        <item>
-	    <p>A call or apply of a literal external fun will be
-	    replaced with a direct call.</p>
-          <p>
-	    Own Id: OTP-15044 Aux Id: ERL-614 </p>
-        </item>
-        <item>
-	    <p>Part of EEP-44 has been implemented.</p>
-	    <p>There is a new predefined macro called
-	    <c>OTP_RELEASE</c> which is an integer indicating the OTP
-	    release number (its value is <c>21</c> in this
-	    release).</p>
-	    <p>There are new preprocessor directives
-	    <c>-if(Condition).</c> and <c>-elif(Condition).</c>. The
-	    <c>if/elif</c> supports the builtin function
-	    <c>defined(Symbol)</c>.</p>
