To use an existing SQL Server

To use an existing SQL Server....

I have a question on database version that are compatible for BE 2012. What and all version of SQL database that will support BE 2012?

"Click Use an existing instance of SQL Server 2005 (SP4a or later) orSQLServer 2008onthe network to store the database on."

Only these two versions (2005 and 2008)?  or 2012 and 2014 as well?
