+[section Tuning classes for fast lexical conversions]
+Because of `boost::lexical_cast` optimizations for `boost::iterator_range<character_type*>`, it is possibile to make very fast lexical conversions for non zero terminated strings, substrings and user-defined classes.
+
+Consider the following example:
+``
+    class example_class {
+        char non_zero_terminated_data[10];
+        std::size_t data_length;
+
+    public:
+        example_class();
+        void fill_data();
+
+        const char* data() const {
+            return non_zero_terminated_data;
+        }
+
+        std::size_t size() const {
+            return data_length;
+        }
+    };
+
+    inline std::ostream& operator << (std::ostream& ostr, const example_class& rhs) {
+        return ostr << boost::make_iterator_range(rhs.data(), rhs.data() + rhs.size());
+    }
+``
+
+This is a good generic solution for most use cases.
+But we can make it even faster for some performance critical applications. During conversion, we loose speed at:
+
+ * `std::ostream` construction     (it makes some heap allocations)
+ * `operator <<`                   (it copyies one by one all the symbols to an instance of `std::ostream`)
+ * `std::ostream` destruction      (it makes some heap deallocations)
+
+We can avoid all of this, by specifieng an overload for `boost::lexical_cast`:
+``
+namespace boost {
+    template <class OutT>
+    OutT lexical_cast(const example_class& rhs) {
+        return boost::lexical_cast<OutT>(
+            boost::make_iterator_range(rhs.data(), rhs.data() + rhs.size())
+        );
+    }
+}
+``
+Now `boost::lexical_cast<some_type>(example_class_instance)` conversions won't copy data and construct heavy STL stream objects. See [link boost_lexical_cast.performance Performance] section for info on `boost::iterator_range` conversion performance.

 [section Changes]

-* [*boost 1.54.0 :]
-
-    * Fix some issues with `boost::int128_type` and `boost::uint128_type` conversions. Notify user at compile time 
-      if the `std::numeric_limits` are not specialized for 128bit types and `boost::lexical_cast` can not make conversions.
-
-* [*boost 1.54.0 :]
-
-    * Added code to convert `boost::int128_type` and `boost::uint128_type` types (requires GCC 4.7 or higher).
-    * Conversions to pointers will now fail to compile, instead of throwing at runtime.
-    * Restored ability to get pointers to `lexical_cast` function (was broken in 1.53.0).
-
 * [*boost 1.53.0 :]

    * Much better input and output streams detection for user defined types.
