database encryption supported in Exchange 2013?

hi,

according to this:  http://technet.microsoft.com/en-us/library/aa998022(v=exchg.80).aspx

MS doesn't support storing Exchange databases on  EFS volumes.

Is the recommendation the same for Exchange 2013?

Is there any support for encrypting databases in an Exchange 2013 environment other than in transit traffic?

Thanks,
