+	    Fix erl_prim_loader errors in handling of primary
+	    archive. The following errors have been corrected:</p>
+          <p>
+	    <list> <item> If primary archive was named "xxx", then a
+	    file in the same directory named "xxxyyy" would be
+	    interpreted as a file named "yyy" inside the archive.
+	    </item> <item> erl_prim_loader did not correctly create
+	    and normalize absolute paths for primary archive and
+	    files inside it, so unless given with exact same path
+	    files inside the archive would not be found. E.g. if
+	    escript was started as /full/path/to/xxx then
+	    "./xxx/file" would not be found since erl_prim_loader
+	    would try to match /full/path/to/xxx with
+	    /full/path/to/./xxx. Same problem with ../. </item>
+	    <item> Depending on how the primary archive was built,
+	    erl_prim_loader:list_dir/1 would sometimes return an
+	    empty string inside the file list. This was a virtual
+	    element representing the top directory of the archive.
+	    This has been removed. </item> </list></p>

+	    The 64-bit windows installer did not look in the right
+	    directories for 64-bit version of Microsoft Visual C++
+	    2010 Redistibutable Package and hence took the wrong
+	    decision about having to install the redistributable
+	    package if the 32-bit version was installed but not the
+	    64-bit and vice versa. This bug has now been fixed
+	    Furthermore the sub-installer for the redistributable
+	    package is now run in silent mode if the erlang installer
+	    is.</p>

+	    Doc fix: link from erlang:now/0 to os:timestamp/0</p>
+          <p>
+	    Sometimes os:timestamp/0 is more appropriate than
+	    erlang:now/0. The documentation for the former has a link
+	    to the latter; this patch adds a link in the other
+	    direction to make os:timestamp/0 more visible. Thanks to
+	    Magnus Henoch</p>

+	    Commit 1eef765 introduced regression (conditional
+	    _always_ evaluates to true) in which
+	    erlang:localtime_to_universaltime/2 stopped working on
+	    systems configured with timezone without DST (i.e. UTC)
+	    on *BSD platforms: 1>

+	    true). ** exception error: bad argument Thanks to Piotr

+	    Relocate bodies of DTrace probes to the statically-linked
+	    VM.</p>
+          <p>
+	    Due to various operating systems (in both the DTrace and
+	    SystemTap worlds) not fully supporting DTrace probes (or
+	    SystemTap-compatibility mode probes) in shared libraries,
+	    we relocate those probes to the statically-linked virtual
+	    machine. This could be seen as pollution of the pristine
+	    VM by a (yet) experimental feature. However:</p>
+          <p>
+	    1. This code can be eliminated completely by the C
+	    preprocessor. 2. Leaving the probes in the dyntrace NIF
+	    shared library simply does not work correctly on too many
+	    platforms. *Many* thanks to Macneil Shonle at Basho for
+	    assisting when my RSI-injured fingers gave out. (note:
+	    Solaris 10 and FreeBSD 9.0-RELEASE can take a long time
+	    to compile)</p>

+	    Supplying a filename longer than the operating system

+	    If Perl was configured to interpret files as being

+	    Fix the erlc -MP flag</p>
+          <p>
+	    Because of a copy-and-paste error in erlc.c, the -MP flag
+	    had the same effect as -MG. As a workaround, you had to
+	    pass +makedep_phony to enable the MP option. This patch
+	    makes -MP work as intended.</p>

+	    Allow mixed IPv4 and IPv6 addresses to sctp_bindx</p>
+          <p>
+	    Also allow mixed address families to bind, since the
+	    first address on a multihomed sctp socket must be bound
+	    with bind, while the rest are to be bound using
+	    sctp_bindx. At least Linux supports adding address of
+	    mixing families. Make inet_set_faddress function
+	    available also when HAVE_SCTP is not defined, since we
+	    use it to find an address for bind to be able to mix ipv4
+	    and ipv6 addresses. Thanks to Tomas Abrahamsson</p>

+	    Fix support for leap seconds-aware timezones</p>
+          <p>
+	    erlang:universaltime_to_localtime is leap seconds-aware
+	    (since 2008), however erlang:localtime_to_universaltime
+	    is not, which gives surprising results on systems
+	    configured with leap seconds-aware timezones: 1>
+	    erlang:universaltime_to_localtime({{2012,1,1},{0,0,0}}).
+	    {{2012,1,1},{0,0,0}} 2>
+	    erlang:localtime_to_universaltime({{2012,1,1},{0,0,0}}).
+	    {{2012,1,1},{0,0,24}} and completely breaks
+	    calendar:local_time_to_universal_time_dst: 3>
+	    calendar:local_time_to_universal_time_dst({{2011,1,1},{0,0,0}}).

+	    erlsrv: gracefully stop emulator on Windows shutdown</p>
+          <p>
+	    Windows will send the SERVICE_CONTROL_SHUTDOWN event to
+	    the service control handler when shutting down the
+	    system. Instead of ignoring the event, erlsrv will now
+	    invoke the stop action. Likewise, the Erlang emulator
+	    (and it's po drivers) must not quit upon reception of the
+	    CTRL_SHUTDOWN_EVENT event in th console control handler.
