-	    <p>For many releases, it has been legal to override a BIF
-	    with a local function having the same name. However,
-	    calling a local function with the same name as guard BIF
-	    as filter in a list comprehension was not allowed.</p>

-	    <p> A new (default) pseudo-random number generator
-	    algorithm Xoroshiro116+ has been implemented in the
-	    <c>rand</c> module. </p><p> The old algorithm
-	    implementations had a number of flaws so they are all
-	    deprecated, but corrected versions of two of them have
-	    been added. See the documentation. </p>

-	    and external funs, as long as they can be created in the

-	    The <c>gen_statem</c> callback <c>Module:init/1</c> has

-          <p>
-	    Improved unicode support for strings. Added normalization
-	    functions in the <c>unicode</c> module. Extended the
-	    <c>string</c> module API with new functions with improved
-	    unicode handling and that works on grapheme clusters. The
-	    new functions operates on the <c>unicode:chardata()</c>
-	    type, thus they also accept <c>UTF-8 binaries</c> as
-	    input. </p>
-          <p>
-	    The old string API have been marked as obsolete. The
-	    return values have been changed for some error cases.</p>

-	    <p>There are two new guard BIFs '<c>floor/1</c>' and
-	    '<c>ceil/1</c>'. They both return integers. In the
-	    '<c>math</c>' module, there are two new BIFs with the
-	    same names that return floating point values.</p>

-	    <p>The EXIT signals received from processes using
-	    <c>proc_lib</c> now looks like EXIT signals from
-	    processes that were spawned using <c>spawn_link</c>. In
-	    particular, that means that the stack trace is now
-	    included in the EXIT signal so that it can see where the
-	    process crashed.</p>

-	    <p><c>sets:add_element/2</c> is faster when adding an
-	    element that is already present, and
-	    <c>sets:del_element/2</c> is faster when the element to

-	    <c>code:modified_modules/0</c> returns all currently
-	    loaded modules that have changed on disk.
-	    <c>code:module_status/1</c> returns the status for a

-	    <p>Each assert macro in <c>assert.hrl</c> now has a

-	    Optimized ETS operations by changing table identifier
-	    type from integer to reference. The reference enables a
-	    more direct mapping to the table with less potential lock
-	    contention and makes especially creation and deletion of
-	    tables scale much better.</p>
-          <p>
-	    The change of the opaque type for the ETS table
-	    identifiers may cause failure in code that make faulty
-	    assumptions about this opaque type.</p>

-	    <p>The shell functions <c>c/1</c> and <c>c/2</c> have
-	    been extended so that if the argument is a module name
-	    instead of a file name, it automatically locates the
-	    .beam file and the corresponding source file, and then
-	    recompiles the module using the same compiler options
-	    (plus any options passed to c/2). If compilation fails,
-	    the old beam file is preserved. Also adds <c>c(Mod, Opts,
-	    Filter)</c>, where the Filter argument allows you to
-	    remove old compiler options before the new options are
-	    added.</p> <p>New utility functions <c>file_find/2/3</c>
-	    and <c>find_source/1/2/3</c> have been added to

-	    names in a portable way.</p>
-	    <p><c>erl_tar</c> now has support for reading tar
-	    archives in the formats currently in common use, such as
-	    v7, STAR, USTAR, PAX, and GNU tar's extensions to the
-	    STAR/USTAR format. When writing tar archives,
-	    <c>erl_tar</c> can now write them in the <c>PAX</c>
-	    format if necessary (for example, to support very long
-	    filenames or filenames with Unicode characters). If
-	    possible, <c>erl_tar</c> will still write tar archives in
-	    the USTAR for maximum portability.</p>

-          <p>
-	    Upgraded the OTP internal PCRE library from version 8.33
-	    to version 8.40. This library is used for implementation
-	    of the <seealso marker="stdlib:re"><c>re</c></seealso>
-	    regular expressions module.</p>
-          <p>
-	    Besides various bug fixes, the new version allows for
-	    better stack protection. In order to utilize this
-	    feature, the stack size of normal scheduler threads is
-	    now by default set to 128 kilo words on all platforms.
-	    The stack size of normal scheduler threads can be set
-	    upon system start by passing the <seealso
-	    marker="erts:erl#sched_thread_stack_size"><c>+sss</c></seealso>
-	    command line argument to the <seealso
-	    marker="erts:erl"><c>erl</c></seealso> command.</p>
-          <p>
-	    See <url
-	    href="http://pcre.org/original/changelog.txt"><c>http://pcre.org/original/changelog.txt</c></url>
-	    for information about changes made to PCRE between the

-	    <p>The format of debug information that is stored in BEAM
-	    files (when <c>debug_info</c> is used) has been changed.
-	    The purpose of the change is to better support other
-	    BEAM-based languages such as Elixir or LFE.</p>
-	    <p>All tools included in OTP (dialyzer, debugger, cover,
-	    and so on) will handle both the new format and the
-	    previous format. Tools that retrieve the debug
-	    information using <c>beam_lib:chunk(Beam,
-	    [abstract_code])</c> will continue to work with both the
-	    new and old format. Tools that call
-	    <c>beam_lib:chunk(Beam, ["Abst"])</c> will not work with
-	    the new format.</p>
-	    <p>For more information, see the description of
-	    <c>debug_info</c> in the documentation for
-	    <c>beam_lib</c> and the description of the
-	    <c>{debug_info,{Backend,Data}}</c> option in the

-	    <p> The new function
-	    <c>error_logger:get_format_depth/0</c> can be used to
