 How to Use PdoSessionHandler to Store Sessions in the Database
 ==============================================================
 
+.. caution::
+
+    There was a backwards-compatability break in Symfony 2.6: the database

 The default Symfony session storage writes the session information to
 file(s). Most medium to large websites use a database to store the session
 values instead of files, because databases are easier to use and scale in a
