Stable IOS version for dot1x on Cisco Catalyst 4500 L3 Sup 6-E

[Capricorn]

Hi!

I am upgrading my IOS on Cisco Catalyst 4500 L3 Sup 6-E to cat4500e-ipbasek9-mz.151-2.SG8.bin and ROM: 12.2(44r)SG11. I can see on Cisco docs that the recommended Rom is 12.2(44r)SG9.

Just want to confirm if its ok to use the above IOS and Rom and they are stable? 

Thanks

Ok I can simple ask the Stable release for Cisco 4500.
