-	    Fix issuing with spaces and quoting in the arguments when
-	    using erlang:open_port spawn_executable on windows. The
-	    behavior now mimics how unix works. This change implies a
-	    backwards incompatibility for how spawn_executable works
-	    on windows.</p>

-	    Fix global call trace when hipe compiled code call beam
-	    compiled functions. Tracing of beam functions should now

-	    Correct cache alignment for ETS <c>write_concurrency</c>
-	    locks to improve performance by reduced false sharing.

-          <p>
-	    All possibly blocking operations in the fd/spawn and
-	    terminal driver have been converted to non-blocking
-	    operations. Before this fix it was possible for the VM to
-	    be blocked for a long time if the entity consuming
-	    stdout/stderr did not consume it fast enough.</p>

-          <p>
-	    Add missing overhead for offheap binaries created from
-	    external format. This fix can improve the garbage
-	    collection of large binaries originating from
-	    <c>binary_to_term</c> or messages from remote nodes.</p>

-	    Ensure hashing of zero is consistent</p>
-	    <p> Erlang treats positive and negative zero as
-	    equal:</p> 
-          <p>
-	    <c>true = 0.0 =:= 0.0/-1</c></p>
-	    <p>However, Erlangs hash functions: hash, phash and
-	    phash2 did not reflect this behaviour. The hash values
-	    produced by the different hash functions would not be
-	    identical for positive and negative zero.</p> <p>This
-	    change ensures that hash value of positive zero is always
-	    produced regardless of the signedness of the zero float,
-	    i.e.,</p>
-          <p>
-	    <c>true = erlang:phash2(0.0) =:=
-	    erlang:phash2(0.0/-1)</c></p>

-	    Ensure NIF term creation disallows illegal floating point
-	    values and too long atoms. Such values will cause a NIF
-	    to throw badarg exception when it returns.</p>

-	    Fix hipe bug when matching a "writable" binary. The bug
-	    has been seen to sometimes cause a failed binary matching
-	    of a correct utf8 character, but other symptoms are also

-	    <p>The time functionality of Erlang has been extended.
-	    This both includes a <seealso
-	    marker="time_correction#The_New_Time_API">new
-	    API</seealso> for time, as well as <seealso
-	    marker="time_correction#Time_Warp_Modes">time warp
-	    modes</seealso> which alters the behavior of the system
-	    when system time changes. <em>You are strongly encouraged
-	    to use the new API</em> instead of the old API based on
-	    <seealso
-	    marker="erlang#now/0"><c>erlang:now/0</c></seealso>.
-	    <c>erlang:now/0</c> has been deprecated since it is and
-	    forever will be a scalability bottleneck. For more
-	    information see the <seealso
-	    marker="time_correction">Time and Time
-	    Correction</seealso> chapter of the ERTS User's
-	    Guide.</p>
-	    <p>Besides the API changes and time warp modes a lot of
-	    scalability and performance improvements regarding time
-	    management has been made internally in the runtime
-	    system. Examples of such improvements are scheduler
-	    specific timer wheels, scheduler specific BIF timer
-	    management, parallel retrieval of monotonic time and
-	    system time on systems with primitives that are not
-	    buggy.</p>

-	    Improved usage of <c>gcc</c>'s builtins for atomic memory
-	    access. These are used when no other implementation of

-	    compiling for ARM when <c>libatomic_ops</c> is not
-	    available.</p>
-          <p>
-	    The largest improvement will be seen when compiling with
-	    a <c>gcc</c> with support for the <c>__atomic_*</c>
-	    builtins (using a <c>gcc</c> of at least version 4.7),
-	    but also when only the legacy <c>__sync_*</c> builtins
-	    are available (using a <c>gcc</c> of at least version
-	    4.1) an improvement can be seen.</p>

-	    Use persistent hashmaps for large Maps <p>Maps will use a

-	    pairs in a Map becomes sufficiently large. The change
-	    will occur when a Map reaches 33 pairs in size but this
-	    limit might change in the future.</p></p>
-	    <p>The most significant impact for the user by this
-	    change is speed, and to a lesser degree memory
-	    consumption and introspection of Maps. Memory consumption
-	    size is probalistic but lesser than <c>gb_trees</c> or
-	    <c>dict</c> for instance. Any other impacts will be
-	    transparent for the user except for the following
-	    changes.</p>
-	    <p>Semantics of Maps have changed in two incompatible
-	    ways compared to the experimental implementation in OTP

-	    Scalability improvement for <seealso
-	    marker="erlang#make_ref/0">erlang:make_ref/0</seealso>,
-	    and other functionality that create references. Each
-	    scheduler now manage its own set of references. By this
-	    no communication at all is needed when creating
-	    references.</p>
-          <p>
-	    Previous implementation generated a strictly
-	    monotonically increasing sequence of references
-	    corresponding to creation time on the runtime system
-	    instance. This is <em>not</em> the case with current
-	    implementation. You can only expect reference to be
-	    unique. The Erlang/OTP documentation has never mentioned
-	    anything else but the uniqueness property, so this change
-	    <em>is</em> fully compatible. The only reason we've
-	    marked this as a potential incompatibility is since an
-	    early draft for an Erlang specification mentions strict
-	    monotonicity as a property.</p>
-          <p>
-	    If you need to create data with a strict monotonicity
-	    property use <seealso
-	    marker="erlang#unique_integer/1">erlang:unique_integer([monotonic])</seealso>.
-	    Do <em>not</em> use the deprecated <seealso

-	    Optimization of timers internally in the VM. This include
-	    process timers (<c>receive ... after</c>), port timers
-	    (<c>driver_set_timer()</c>) as well as BIF timers
-	    (<c>erlang:send_after()</c>/<c>erlang:start_timer()</c>).</p>
-          <p>
-	    Each scheduler thread now has its own lock-free timer
-	    service instead of one locked central service. This
-	    dramatically improves performance of timer management on
-	    systems with a large amount of schedulers and timers.</p>
-          <p>
-	    The timer service internal data structure has also been
-	    optimized to be able to handle more timers than before.
-	    That is, each timer service is by its self able to handle
-	    more timers without dramatic performance loss than the
-	    old centralized timer service.</p>
-          <p>
-	    The API of BIF timers has also been extended. Timeout
-	    values are for example no longer limited to 32-bit
-	    integers. For more information see the documentation of
-	    <seealso

-	    Previously, the emulator would generate a whole string
-	    with values and call the error_logger passing
-	    <c>"~s~n"</c>. This changes it to a format string
-	    containing <c>~p</c> with the respective values as
