Latest SP for Solution Manager

Hi,

I have SAP Solution Manager 4.0 SR3 DVD. I am not able to find what SP Stack it is on and what should be the latest I should download now.

When I check in System Status of solman server it shows ...

SAP BASIS on Patch Level 0012 &

SAP ABAP on Patch Level 0012.

and in Java side i see : sap.com/SAP-JEECOR 7.00 SP12

If my SP Stack is SP12 then what is the latest I should upgrade to.

I am not able to find SR3 on Solman Stack Schedule.
