+	    <p>From this release, the previously experimental
+	    halfword emulator is now official. It can be enabled by
+	    giving the <c>--enable-halfword-emulator</c> option to
+	    the <c>configure</c> script.</p>
+	    <p>The halfword emulator is a 64-bit application, but
+	    uses halfwords (32-bit words) for all data in Erlang
+	    processes, therefore using less memory and being faster
+	    than the standard 64-bit emulator. The total size of all
+	    BEAM code and all process data for all processes is
+	    limited to 4Gb, but ETS tables and off-heap binaries are
+	    only limited by the amount of available memory.</p>

+	    32-bit atomic memory operations have been introduced
+	    internally in the run time system, and are now used where
+	    appropriate. There were previously only atomic memory
+	    operations of word size available. The 32-bit atomic
+	    memory operations slightly reduce memory consumption, and
+	    slightly improve performance on 64-bit runtime systems.</p>

+	    Write accesses to ETS tables have been optimized by
+	    reducing the amount of atomic memory operations needed

+	    Strange C coding in the VM made the -D_FORTIFY_SOURCE
+	    option to gcc-4.5 react badly. The code is now cleaned up
+	    so that it's accepted by gcc-4.5.</p>

+	    The memory footprint for loaded code has been somewhat
+	    reduced (especially in the 64-bit BEAM machine).</p>

+	    The maximum number of allowed arguments for an Erlang
+	    function has been lowered from 256 to 255, so that the
+	    number of arguments can now fit in a byte.</p>
