-
-    <p>The C++ built-in <code>dynamic_cast</code> can be used for downcasts and

-    works on references, can be used on pointers through the ugly expression
-    &amp;<code>dynamic_cast&lt;T&amp;&gt;(*p)</code>, which causes undefined
-    behavior if <code>p</code> is <code>0</code>. The <code>polymorphic_cast</code>

-
-    <p>A <code>polymorphic_downcast</code> should be used for

-</pre> where <code>x</code> is the source pointer.  This approach
-    ensures that not only is a non-zero pointer returned, but also
-    that it is correct in the presence of multiple inheritance.
-    Attempts to crosscast using <code>polymorphic_downcast</code> will

+	and writing floating-point numbers. For numerics that have a corresponding specialization of
+	<code>std::numeric_limits</code>, the current version now chooses a precision to match.
+	<li>The previous version of <code>lexical_cast</code> did not support conversion to or from any
+	wide-character-based types. For compilers with full language and library support for wide characters,
+	<code>lexical_cast</code> now supports conversions from <code>wchar_t</code>, <code>wchar_t *</code>,
+	and <code>std::wstring</code> and to <code>wchar_t</code> and <code>std::wstring</code>.
+	<li>The previous version of <code>lexical_cast</code> assumed that the conventional stream extractor
+	operators were sufficient for reading values. However, string I/O is asymmetric, with the result
+	that spaces play the role of I/O separators rather than string content. The current version fixes
+	this error for <code>std::string</code> and, where supported, <code>std::wstring</code>:
+	<code>lexical_cast&lt;std::string&gt;("Hello, World")</code> succeeds instead of failing with
+	a <code>bad_lexical_cast</code> exception.
+	<li>The previous version of <code>lexical_cast</code> allowed unsafe and meaningless conversions to
+	pointers. The current version now throws a <code>bad_lexical_cast</code> for conversions to pointers:
+	<code>lexical_cast&lt;char *&gt;("Goodbye, World")</code> now throws an exception instead of
+	causing undefined behavior.
