+	    <p> Dets tables are no longer fixed while traversing with
+	    a bound key (when only the objects with the right key are
+	    matched). This optimization affects the functions
+	    <c>match/2</c>, <c>match_object/2</c>, <c>select/2</c>,
+	    <c>match_delete/2</c>, and <c>select_delete/2</c>. </p>

+	    <p> The linter now warns for opaque types that are not
+	    exported, as well as for under-specified opaque types.

+        <item>
+	    <p> The type <c>file:name()</c> has been substituted for
+	    the type <c>file:filename()</c> in the following
+	    functions in the <c>filename</c> module:
+	    <c>absname/2</c>, <c>absname_join/2</c>, <c>join/1,2</c>,
+	    and <c>split/1</c>. </p>

+          <p>
+	    If a child process fails in its start function, then the
+	    error reason was earlier only reported as an error report
+	    from the error_handler, and supervisor:start_link would
+	    only return <c>{error,shutdown}</c>. This has been
+	    changed so the supervisor will now return
+	    <c>{error,{shutdown,Reason}}</c>, where <c>Reason</c>
+	    identifies the failing child and its error reason.
+	    (Thanks to Tomas Pihl)</p>

+	    <p>Where necessary a comment stating encoding has been
+	    added to Erlang files. The comment is meant to be removed
+	    in Erlang/OTP R17B when UTF-8 becomes the default
+	    encoding. </p>

+	    <p> The contracts and types of the modules

+	    Fix bug in queue:out/1, queue:out_r/1 that makes it
+	    O(N^2) in worst case. Thanks to Aleksandr Erofeev.</p>

+	    <p> There are new functions in the <c>epp</c> module
+	    which read the character encoding from files. See
+	    <c>epp(3)</c> for more information. </p>

+        </item>
+        <item>
+	    <p> The functions in <c>io_lib</c> have been adjusted for
+	    Unicode. The existing functions <c>write_string()</c> and
+	    so on now take Unicode strings, while the old behavior
+	    has been taken over by new functions
+	    <c>write_latin1_string()</c> and so on. There are also
+	    new functions to write Unicode strings as Latin-1
+	    strings, mainly targetted towards the Erlang pretty
+	    printer (<c>erl_pp</c>). </p>
+          <p>

+        </item>
+        <item>
+	    <p> The new functions <c>proc_lib:format/2</c> and
+	    <c>erl_parse:abstract/2</c> accept an encoding as second
+	    argument. </p>

+	    Increased potential concurrency in ETS for
+	    <c>write_concurrency</c> option. The number of internal
+	    table locks has increased from 16 to 64. This makes it
+	    four times less likely that two concurrent processes
+	    writing to the same table would collide and thereby
+	    serialized. The cost is an increased constant memory
+	    footprint for tables using write_concurrency. The memory
+	    consumption per inserted record is not affected. The
+	    increased footprint can be particularly large if
+	    <c>write_concurrency</c> is combined with
+	    <c>read_concurrency</c>.</p>
