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> <p>(Thanks to Winston Smith for the AVR32-Linux cross configuration and testing)</p> <p> *** POTENTIAL INCOMPATIBILITY ***</p> <p> Own Id: OTP-8323</p> </item> <item> <p> The crypto module now supports Blowfish in ECB, CBC and OFB modes. (Thanks to Paul Oliver.)</p> <p> Own Id: OTP-8331</p> </item> <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> <p> Own Id: OTP-8343</p> </item> </list> </section> </section> <section><title>Crypto 1.6.3</title> <section><title>Fixed Bugs and Malfunctions</title> <list> <item> <p> Suppressed false valgrind errors caused by libcrypto using uninitialized data as entropy.</p> <p> Own Id: OTP-8200</p> </item> </list> </section> <section><title>Improvements and New Features</title> <list> <item> <p> The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.</p> <p> Own Id: OTP-8201</p> </item> <item> <p> When the crypto application failed to load the OpenSSL/LibEAY shared object, error indication was sparse.
