Version 11.5.2

11.5.2 contains all fixes from 11.5.1 HF8 except one (ASM)

 

496849-4 We fixed a vulnerability in the ASM/DPI/FPS signature update mechanism

 

If it makes sense to install it, up to you. What could make the difference for some:

 

sol5903: BIG-IP software support policy

 

11.5.2 is the first release with long time support, since 10.1.0.

 

But its only one side of the coin.

 

In my opinion, you only need 5 years for static environments and less complex bigip systems.

 

If you are running more modules on the f5 and especially security modules, you dont need it, because you will do more often a release upgrade. Why? Because of new features in a new release and because of bugs, which will be fixed in a later release and not in the same.
