C160 OS version

[KTD1]

Hi everyone.  Found out that my C160s can't upgrade beyond version 8.5.7-043.....  Does anyone know why?  Is there a technical reason for this - all of my appliances are running very lean, and can easily handle the load on them, thus there is no plan to upgrade appliances until these go EOS which is July of 2017.

Are there any security issues being tied to this older version - any major new features that i'm missing?

thank you.

End of Hardware support is 2017, End of SW Maint release was July 19, 2015.

I think the x60s are still 32 bit, and the new OS's are 64 bit.
