	    <p>When specifying the value for an OCTET STRING in a
	    specification, the ASN.1 standard clearly states that the
	    value must be either a bstring or an hstring, but NOT a
	    cstring. The ASN.1 compiler will now generate a
	    compilation error if the value of an OCTET STRING is
	    given as a character string.</p>
	    <p>That is, the following example is now illegal:</p>
	    <p><c>string OCTET STRING ::= "Now illegal"</c></p>

	    <p>The OCTET STRING and BIT STRING types now have a more
	    natural mapping to Erlang types (binary and bitstring,
	    respectively), which is more efficient and will avoid
	    useless conversions between lists and
	    binaries/bitstrings.</p>
	    <p>This is an incompatible change. To revert to the old
	    mapping to support existing applications, use the
	    <c>legacy_erlang_types</c> option.</p>
	    <p>Impact: There is a potential for better performance,
	    as it is now possible to avoid conversions between lists
	    and binaries both in the generated ASN.1 encode/decode
	    code and in the application itself.</p>

	    <p>The options for the ASN.1 compiler has been

	    <c>optimize</c>, <c>nif</c>, and <c>driver</c> are no
	    longer needed. The old options will still work, but will
	    issue a warning.</p>
	    <p>Another change is that generated <c>encode/2</c>
	    function will always return a binary (some backends used

	    file if you need to remove the output file.)</p>
	    <p>The '<c>BIT STRING</c>' type will now be decoded as

	    pass the nif option to erlc or asn1rt:compile when

	    support was more or less non-existing as well as broken.
	    Please, note that the cross compilation support should

	    href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">DESTDIR</url>.
	    The old broken <c>INSTALL_PREFIX</c> has also been fixed.

	    <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 ERTS 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.

            A new option <c>{n2n,TypeName}</c> can be used to
	    enable generation of conversion functions from name to number 
	    and vice versa for selected ENUMERATION types. 
	    The option can be repeated many times in order to specify several 
	    types in the same file.<br/>
	    If the <c>TypeName</c> specified does not exists or is not an 
	    ENUMERATION type, the compilation will be terminated with an 
	    error code.<br/>
	    Below follows an example on how to use the option from the command line with <c>erlc</c>:<br/>
	    <c>erlc -bper+"{n2n,'CauseMisc'}" +"{n2n,'CausePcl'}" MyModyle.asn</c>
