The default character set for <span class="function"><a href="function.htmlspecialchars.html" class="function">htmlspecialchars()</a></span>
and <span class="function"><a href="function.htmlentities.html" class="function">htmlentities()</a></span> is now <em>UTF-8</em>,
instead of <em>ISO-8859-1</em>. Note that changing your output
charset via the <a href="ini.core.html#ini.default-charset" class="link">default_charset</a>
configuration setting does not affect htmlspecialchars/htmlentities unless
you are passing "" (an empty string) as the encoding parameter to your
<span class="function"><a href="function.htmlspecialchars.html" class="function">htmlspecialchars()</a></span>/ <span class="function"><a href="function.htmlentities.html" class="function">htmlentities()</a></span> calls.
Generally we do not recommend doing this because you should be able to
change your output charset without affecting the runtime charset used by
these functions. The safest approach is to explicitly set the charset on
each call to <span class="function"><a href="function.htmlspecialchars.html" class="function">htmlspecialchars()</a></span> and
<span class="function"><a href="function.htmlentities.html" class="function">htmlentities()</a></span>.

<a href="book.snmp.html" class="link">SNMP</a> now has an OOP API.

<span class="simpara">
Functions now return <strong><code>FALSE</code></strong> on every error condition including SNMP-related
(no such instance, end of MIB, etc). Thus, in particular, breaks previous behavior
of get/walk functions returning an empty string on SNMP-related errors.

Multi OID get/getnext/set queries are now supported.

<span class="simpara">
Dropped UCD-SNMP compatibility code, consider upgrading to net-snmp v5.3+, Net-SNMP v5.4+ is
required for Windows version.

In sake of adding support for IPv6 DNS name resolution of
remote SNMP agent (peer) is done by extension now, not by Net-SNMP library anymore.
