+	    <p>Fix binary and iolist overflow problems. Typically
+	    problems arose in length calculation where the result

+	    Using the old erlang shell (i.e. erl instead on werl) on
+	    windows and doing several init:restart's would eventually
+	    hang the VM. That is no longer the case.</p>

+	    The documentation for <c>init:get_args/0</c> has been
+	    removed. <c>init:get_args/0</c> itself was deprecated in
+	    R9C and removed in R12B. (Thanks to Eric Pailleau.)</p>

+	    Allow user to specify the IP address epmd binds to</p>
+          <p>
+	    The IP address(es) epmd binds to can now be specified by
+	    the user, either via epmd's new "-address" option or (if
+	    that's not used) by setting the environment variable
+	    ERL_EPMD_ADDRESS. Multiple addresses may be specified
+	    using a comma-separated list. If the loopback address is
+	    not in this list, it will be added implicitly, so that
+	    the daemon can be queried by an interactive epmd
+	    process.(Thanks to Holger Wei�)</p>

+	    epmd: include host address in local access check</p>
+          <p>
+	    In FreeBSD jails, the source and destination address of
+	    connections to localhost are changed to be the IP address
+	    of the jail. Consider connections from the host's IP
+	    address to itself (e.g., the source and destination
+	    address match) to be local for the access control checks.

+	    Fix list returned by net_kernel:epmd_module</p>
+          <p>
+	    Function epmd_module of net_kernel returns a list instead
+	    of an atom, when the epmd_module-flag is used. (Thanks to
+	    Markus Knofe)</p>

+	    Fix epmd's dbg_perror() output</p>
+          <p>
+	    The dbg_perror() function now hands the current errno
+	    value over to dbg_gen_printf(). This fixes the problem
+	    that errno had been reset to zero by the time it was used
+	    (to print the corresponding error message) in the
+	    dbg_gen_printf() function. (Thanks to Holger Wei�)</p>

+	    heart: remove garbage appended to heart command</p>
+          <p>
+	    heart:get_cmd/0 is documented to return an empty string
+	    if the command is cleared. get_cmd/0 returns 2 extra
+	    bytes: 1 byte for the trailing null, 1 byte from the op
+	    (the op is an unsigned char and 2 bytes are allocated for
+	    it in the returned buffer). (Thanks to Michael Santos)</p>

+	    file: fix hang reading compressed files</p>
+          <p>
+	    The gzio driver goes into an infinite loop when reading
+	    past the end of a compressed file. Reported-By: Alex
+	    Morarash (Thanks to Michael Santos)</p>

+	    Fix format specifiers in erl_exit messages</p>
+          <p>
+	    Fix an error message by using an unsigned integer
+	    specifier as seen in a tweet by @metabrew: #erlang VM
+	    crashed with "no next heap size found: -2090496108,
+	    offset 0", suddenly allocated all available RAM</p>
+          <p>

+	    Teach run_erl RUN_ERL_DISABLE_FLOWCNTRL for disabling
+	    flow control</p>
+          <p>
+	    Flow control can cause unwanted behaviour of the beam
+	    process, if accidentally hit Ctrl-S (instead of Ctrl-D to
+	    detach) the entire beam may be blocked.</p>
+          <p>
+	    Fix this problem by making it possible to turn off flow
+	    control by setting the environment variable
+	    RUN_ERL_DISABLE_FLOWCNTRL. (Thanks to Jonas Faklkevik)</p>

+	    <p>The following bugs due to missing memory barriers have
+	    been fixed:</p> <list> <item><p> ETS tables using the
+	    <c>write_concurrency</c> option could potentially get
+	    into an internally inconsistent state. </p></item>
+	    <item><p> ETS tables using the <c>ordered_set</c> option
+	    could potentially get into an internally inconsistent
+	    state. </p></item> <item><p> A number of memory barriers
+	    have been added when building with the
+	    <c>libatomic_ops</c> API (i.e. when passing
+	    <c>--with-libatomic_ops=PATH</c> to <c>configure</c>) and
+	    the tilera atomics API (i.e. when building for the tilera
+	    chip). Note that these bugs were due to erroneous usage
+	    of the APIs, and not in the implementations of the APIs.
+	    When using these APIs the following bugs where
+	    present:</p> <list> <item><p> The BIF
+	    <c>erlang:ports/0</c> could return an erroneous result.
+	    </p></item> <item><p> A thread blocking other threads
+	    during code loading, or setup of tracing could
+	    potentially read invalid data. </p></item> <item><p>
+	    Fixation of ETS tables could potentially get into an
+	    internally inconsistent state. </p></item> </list>

+	    A process being garbage collected by another process
+	    could be scheduled on another scheduler. This prevented
+	    this scheduler from doing any useful work until the
+	    garbage collection was done. This either occurred due to
+	    a explicit call to the <c>garbage_collect/1</c> BIF, or
+	    due to a garbage collection part of code loading. A
+	    process being garbage collected like this will now not be
+	    scheduled until the garbage collection has completed.</p>

+	    Due to standard library DLL mismatches between versions
+	    of OpenSSL and Erlang/OTP, OpenSSL is now linked
+	    statically to the crypto driver on Windows. This fixes
+	    problems starting crypto when running Erlang as a service
+	    on all Windows versions.</p>
