 Version 1.6.0
 
-  * Support for mapping std::vector<char> to the BLOB (or equivalent)
-    types. For more information, refer to chapters 11 (for MySQL), 12
-    (for SQLite) and 13 (for PostgreSQL) in the ODB manual.
+  * Support for value wrappers. An ODB value wrapper is a class template
+    that wraps a value type. Common examples of wrappers are smart pointers,
+    holders, and "optional value" containers such as boost::optional. A
+    wrapper can be transparent or it can handle the NULL semantics. To
+    allow the easy conversion of value types that do not support the NULL
+    semantics into the ones that do, the odb::nullable class template has
+    been added. ODB also now includes built-in support for std::auto_ptr
+    and std::tr1::shared_ptr smart pointers as value wrappers as well as
+    for boost::shared_ptr and QSharedPointer via the Boost and Qt profiles.
+    For more information, refer to Section 7.3, "NULL Value Semantics" in
+    the ODB manual.
+
+  * Support for the boost::optional container in the Boost profile. A data
+    member of the boost::optional type is mapped to a column that can have
+    a NULL value. For more information, refer to Section 15.3 "Optional
+    Library" in the ODB manual.
+
+  * Support for mapping std::vector<char> to the BLOB (or equivalent) types.
+    For more information, refer to chapters 11 (for MySQL), 12 (for SQLite)
+    and 13 (for PostgreSQL) in the ODB manual.
