What is the latest OS for the Cisco ASA 5505

Cisco ASA 5505 and I need to upgrade to latest IOS.  I upgraded it to 8.4(6) as several documents say is the interim step for anything later.  But I cannot find docs that reference the 5505 going further.  I see a lot of 5506-x references.  I see that htere is also a 8.4(7) as the latest in the 8.x series, but seem to remember putting 5505's at 9.1 and 9.2 in years past, but am not sure.  Can anyone tell me the latest version of IOS to put a 3 year old ASA 5505 at?

8.4(6) is the best option to proceed with for ASA 5505 otherwise you will get upgrade issues if you proceed with other versions of IOS.Can you specify or elaborate your ASA configuration i mean what all things you need to configure on ASA such as failover,VPN ,Cisco VPN AnyConnect ,Failover (Statefull or Stateless)  etc etc.

Thanks.  This 5505 will be mostly used as a router on the perimeter of the network to divide a DMZ, once it is updated.  No VPN, No failover.  It will have public IPS on it, but will not be doing NAT or protecting the internal network.
