+Version 1.2.0

+  * New namespace, odb::core, contains using-declarations for the core ODB
+    constructs, such as the database, transaction, etc. The primary use of
+    this namespace is in the using-directives:
+
+    using namespace odb::core;
+
+    The above form should be preferred over the old variant:
+
+    using namespace odb;
+
+    The new approach brings all the essential ODB names into the current
+    namespace without any of the auxiliary objects such as traits, etc.,
+    which minimizes the likelihood of conflicts with other libraries.
+    Note that you can still use the odb namespace when qualifying
+    individual names, for example, odb::database.
