<p>
Added extended_errors option to ODBC</p>
<p>
When enabled, this option alters the return code of ODBC
operations that produce errors to include the ODBC error
code as well as the native error code, in addition to the
ODBC reason field which is returned by default. Thanks to
Bernard Duggan.</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>
An ODBC process should exit normally if its client exits
with 'shutdown'</p>
<p>
There is nothing strange about the client shutting down,
so the ODBC process should exit normally to avoid
generating a crash report for a non-problem. (Thanks to
Magnus Henoch)</p>

<p>Erlang/OTP can now be built using parallel make if you
limit the number of jobs, for instance using '<c>make
-j6</c>' or '<c>make -j10</c>'. '<c>make -j</c>' does not
work at the moment because of some missing
dependencies.</p>

<section><title>Improvements and New Features</title>
<list>
<item>
<p>
Ipv6 is now supported on Windows as well as on UNIX for
internal socket communication. (ODBC uses sockets instead
of the "Erlang port pipes" as some ODBC-drivers are known
to mess with stdin/stdout.) </p>
<p>
Loopback address constants are used when connecting the
c-side to the erlang-side over local socket API avoiding
getaddrinfo problems, and the {ip, loopback} option is
added as a listen option on the erlang-side. Also cleaned
up the TIME_STAMP contribution.</p>

<p>
ODBC now handles the types SQL_WCHAR and SQL_WVARCHAR.
Thanks to Juhani R�nkimies. ODBC also has a new
connection option to return all strings as binaries and
also expect strings to be binaries in the param_query
function. These changes provides some unicode support.</p>

<p>Cross compilation improvements and other build system
improvements.</p>
<p>Most notable:</p> <list><item> Lots of cross
compilation improvements. The old cross compilation
support was more or less non-existing as well as broken.
Please, note that the cross compilation support should
still be considered as experimental. Also note that old
cross compilation configurations cannot be used without
modifications. For more information on cross compiling
Erlang/OTP see the <c>$ERL_TOP/INSTALL-CROSS.md</c> file.
</item><item> Support for staged install using <url
href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">DESTDIR</url>.
The old broken <c>INSTALL_PREFIX</c> has also been fixed.
For more information see the <c>$ERL_TOP/INSTALL.md</c>
file. </item><item> Documentation of the <c>release</c>
target of the top <c>Makefile</c>. For more information
see the <c>$ERL_TOP/INSTALL.md</c> file. </item><item>
<c>make install</c> now by default creates relative
symbolic links instead of absolute ones. For more
information see the <c>$ERL_TOP/INSTALL.md</c> file.
</item><item> <c>$ERL_TOP/configure --help=recursive</c>
now works and prints help for all applications with
<c>configure</c> scripts. </item><item> Doing <c>make
install</c>, or <c>make release</c> directly after
<c>make all</c> no longer triggers miscellaneous
rebuilds. </item><item> Existing bootstrap system is now
used when doing <c>make install</c>, or <c>make
release</c> without a preceding <c>make all</c>.
</item><item> The <c>crypto</c> and <c>ssl</c>
applications use the same runtime library path when
dynamically linking against <c>libssl.so</c> and
<c>libcrypto.so</c>. The runtime library search path has
also been extended. </item><item> The <c>configure</c>
scripts of <c>erl_interface</c> and <c>odbc</c> now
search for thread libraries and thread library quirks the
same way as <c>erts</c> do. </item><item> The
<c>configure</c> script of the <c>odbc</c> application
now also looks for odbc libraries in <c>lib64</c> and
<c>lib/64</c> directories when building on a 64-bit
system. </item><item> The <c>config.h.in</c> file in the
<c>erl_interface</c> application is now automatically
generated in instead of statically updated which reduces
the risk of <c>configure</c> tests without any effect.
</item></list>
<p>(Thanks to Henrik Riomar for suggestions and
testing)</p>

configuration and testing)</p>

<item>
<p>The documentation is now possible to build in an open
source environment after a number of bugs are fixed and
some features are added in the documentation build
process. </p>
<p>- The arity calculation is updated.</p>
<p>- The module prefix used in the function names for
bif's are removed in the generated links so the links
will look like
"http://www.erlang.org/doc/man/erlang.html#append_element-2"
instead of
"http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".</p>
<p>- Enhanced the menu positioning in the html
documentation when a new page is loaded.</p>
<p>- A number of corrections in the generation of man
pages (thanks to Sergei Golovan)</p>
<p>- The legal notice is taken from the xml book file so
OTP's build process can be used for non OTP
applications.</p>

The odbc application now has to be explicitly started and
stopped e.i. it will not automatically be started as a
temporary application as it did before. Although a
practical feature when testing things in the shell, it is
not desirable that people take advantage of this and not
start the odbc application in a correct way in their
products. Added functions to the odbc API that calls
application:start/stop.</p>
