<item>
<p>The old legacy <c>erl_interface</c> library (functions
with prefix <c>erl_</c>) is deprecated as of OTP 22, and
will be removed in OTP 23. This does not apply to the
<c>ei</c> library. Reasonably new <c>gcc</c> compilers
will issue deprecation warnings. In order to disable
these warnings, define the macro
<c>EI_NO_DEPR_WARN</c>.</p>

Make <c>ei_connect</c> and friends also accept state
<c>ok_simultaneous</c> during handshake, which means the

Fixed bug in <c>ei_receive_msg</c>,
<c>ei_xreceive_msg</c>, <c>ei_receive_msg_tmo</c> and
<c>ei_xreceive_msg_tmo</c>. The <c>x->index</c> was

safe.</p>

<p>
Remove generation of atoms in old latin1 external format
in the distribution between erlang nodes,
<c>erl_interface</c>, and <c>jinterface</c>. The new utf8
format for atoms was introduced in OTP R16. An OTP 20
node can therefore not connect to nodes older than R16.</p>
<p>
Atoms that can be encoded using latin1 are still encoded
by <c>term_to_binary()</c> using latin1 encoding. Note
that all atoms will by default be encoded using utf8 in a
future Erlang/OTP release. For more information see the
documentation of <seealso
marker="erts:erlang#term_to_binary/2"><c>erlang:term_to_binary/2</c></seealso>.</p>

Handle terms (pids,ports and refs) from nodes with a
'creation' value larger than 3. This is a preparation of
the distribution protocol to allow OTP 19 nodes to
correctly communicate with future nodes (20 or higher).
The 'creation' value differentiates different
incarnations of the same node (name).</p>

Do not accept Nan and Infinity values</p>

Erlang does not accept these values, so we return an
error in the C interface rather than letting them through
to the Erlang VM, which rejects the message with a

ei: integer overflow in string/atom encoding</p>
<p>
ei_encode_atom() and ei_encode_string() use strlen() to
get the length of the buffer. As strlen() returns an
unsigned long long and both ei functions take a signed
integer, the length fields may overflow.</p>

Check so that the results of strlen can be held in a
signed integer. (Thanks to Michael Santos)</p>

Fix using sizeof() for array given as function argument</p>
<p>
When using the sizeof() operator for an array given as
function argument it returns the size of the pointer. In
this case, the affected function hex(char digest[16],
char buff[33]) will just print 4 or 8 byte instead of the
full length of 16 bytes, on 32bit and 64bit systems
respectively. (Thanks to Cristian greco)</p>

<p>compact IEEE 754 double encoding in external binary
format for ei</p> <list><item><p>Implement the compact
IEEE 754 double encoding in external binary format for
ei. Encoding for ei now always produces the NEW_FLOAT_EXT
format. Decoding and term printing handle both the old
ERL_FLOAT_EXT encoding and the new NEW_FLOAT_EXT
encoding. </p></item> <item><p>Legacy erl_interface code
also handles the new encoding, but still produces the
ERL_FLOAT_EXT encoding by default.</p></item>
<item><p>Also enable the DFLAG_NEW_FLOATS distribution
flag.</p></item> <item><p>ei_get_type() will return
ERL_FLOAT_EXT regardless if the external format is
encoded with ERL_FLOAT_EXT or NEW_FLOAT_EXT for
doubles.</p></item> <item><p>Reduce the number of copies
of the code for encoding and decoding doubles throughout
ei and erl_interface by instead calling the ei encoding
and decoding functions wherever possible.</p></item>
<item><p>Restore commented-out float tests in
ei_decode_SUITE and ei_encode_SUITE in
lib/erl_interface/test. Modify them to make them match
the style of other tests in the same suites.</p></item>
</list> <p>These changes are based on an ei float patch
from Serge Aleynikov originally submitted against R12B-2
in July 2008 and reworked by Steve Vinoski May 2010.</p>

Document debug support.</p>
<p>
Debug trace output for connection activity could be
enabled setting the trace level as an integer to the
EI_TRACELEVEL environment variable. This option could
also be read and set from a running program using
ei_get_tracelevel(void) and ei_set_tracelevel(int).</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.
